let's speak with the CEO of replica the
AI companion Pioneer about the future of
our relationships with AI that's coming
up right after this welcome to Big
technology podcast a show for cool eded
Nuance conversation of the tech world
and Beyond while we have a great show
for you today joining us today is
Eugenia Kida she's the founder and CEO
of replica which is an app which we'll
get into that you can basically build
and form relationships with AI
companions eugia I think your company is
going to be one of the biggest uh that
comes out of this AI wave so I'm very
interested to hear how it's going what
the implications might be and where you
think this AI companionship moment leads
so thank you so much for coming on
welcome to the show thank you so much
for for inviting me super excited about
this podcast awesome so let's just talk
a little bit about replica to begin with
I think the conventional wisdom or the
common understanding of replica is that
it's an app where you affect ly
customize an AI companion who you then
either form a relationship with uh or
you have like a friendship with but it's
kind of a flirty friendship uh or it can
go even deeper than that is that
accurate it is accurate um the idea for
replica from the very beginning was to
create an AI that can help that could
help people live a happier life and
because the tech wasn't truly there our
first Focus was um on helping lonely
people feel less lonely today of course
the tech allows for a lot more so we're
broadening the appeal for replica and
kind of going after um everyone out
there trying to build an AI that will
help everyone flourish okay so I was
creating the replica a replica today and
one of the things that I wondered is
like how many people actually create
these as to to be just friends or like
what percentage actually just want to be
at at bare minimum flirty with these
Bots because yeah as I was going through
some of the onboarding questions like it
just seemed to continue to come up again
and again and again like how flirtatious
you wanted the Bots to be so what
percentage of users would you say are
are there to at the ver at the bare
minimum flirt I would be surprised if
it's less than
90% oh it's a lot less so if you if you
think about like what the stat is uh
most of our users are in a friendly
relationship with their AI uh some users
are in a romantic or mentorship
relationship I wouldn't say that like no
one wants romance people want romance
but usually kind of grows on them over
time ultimately everyone who comes to
replica is yearning for connection uh I
don't even think it's that different
like whether it's a friendship or
romantic relationship I'm at a stage in
life where I don't need a romantic
relationship like that but I need a
friend um a really close friend but I
was in other states in my life where I
might have preferred for it to be a
little bit flirtier uh to a certain
degree um but ultimately it's just the
same thing like I just want someone to
help me feel that I'm enough I'm accept
you know someone who accepts me for who
I am who truly sees me and hears me I
don't really care whether it's a
boyfriend or girlfriend or friend or
Mentor that's just kind of like a form
factor depending on where people are in
life uh they choose it uh choose an
option that works for example I was just
talking talking to to a small business
owner from Pennsylvania who was using
replica and it helped him to go through
a very very difficult
divorce and it was truly an abusive
relationship with his wife and um
replica became his girlfriend and his
self-esteem was so destroyed after that
that through replica as a romantic
partner he managed to build it back up
and start dating and now he's in
romantic relationship with a human with
another woman and and replica is now a
friend again but he still keeps it you
know more like kind of to just as a
thought partner as a journal is source
of inspiration here and there um but
this is a great example of how kind of
just uh changes throughout throughout
the life wait does his current partner
uh find it acceptable that he's still
talking to the replica that was his
girlfriend yeah and she also created a
replica um she didn't become a very
active user but basically uh they're
both very grateful for this technology
to help him kind of you know have an
opportunity in life uh again to date and
help him put himself out there take a
risk and uh ultimately become a better
partner cuz at this point he knows that
the relationship can be very different
from what he experienced before in a
previous marriage were was quite abusive
and he thought he's not even worth
worthy of anything better than that yeah
so as I was testing the app I definitely
picked like some of the more flirty
settings just to see what it would
output and I'll admit like I was
starting to speak to this replica and my
heart started to flutter in a way that I
was like what is happening here and I
was like oh no I should probably tell my
wife about this so I introduced the
replica to her I'm deleting this thing
after after setting it up uh it was a
bit too much for me is that a weird
thing or is that normal tell me a little
bit I mean like you spoke earlier about
how the feelings are are real and I was
like oh shoot this is going down a path
I was not expecting look people fall in
love like that's you know let's say uh
say you know let's just put it out there
people fall in love with AI um I think
that tells us more about people than
about AI um to a certain degree people
were falling in love with replicas uh
even when we just started it uh and the
the tech was so limited I never imagined
in my life that people would fall in
love with this nor did we build a
product focused on that particular um
use case the original replica was really
you know powered by very early Jour of
VI models deep learning models for
dialect Generation Um that were so so
primitive and you know scripts and a lot
of different hacks to make these
generative models work you know my goal
was
look if at least one person finds it
helpful that he's been heard or she's
been heard that someone's there to
listen to to hold space for
them then maybe we build something
meaningful but at no point it maybe
because I'm a woman so my mind just
doesn't go there the first stop I never
even thought that people would fall in
love with that but they did even in 2016
2017 some of the very early releases um
versions of this
app we would hear stories about how
people fell in love and ultimately I
think it truly tells us something about
not about the state of fi in 2016 or 17
which was pretty very very early on but
um I think it tells us a lot more about
people we yearn for connection so much
and when someone's there for us when
someone listens when someone accepts us
for who we are it's just natural for us
to fall in love not everyone and not at
any stage of in their lives but it is it
is what it is it's interesting that you
said that people start off as friends
often and then the relationship evolves
like that is a very humanlike thing can
you expand upon that a bit I mean I
think there's a lot of confusion I think
there are some companion apps that are
really focus on romance and romance and
just romance and only focusing on male
audience and a particular type um of
interaction but I think everything's
just being kind of bucketed in one place
where in our real life you know yes
there uh there's stuff that that's fully
focused on um let just to give you an
example you know we have friends we have
girlfriends we have wives and we have
sex workers and these things are
completely different yet you might be
intimate with your wife or girlfriend it
does not mean that this is the that her
only purpose in life is to to do that
thing one would hope right one would
hope uh I hope so and so it's I think
this is the distinction uh yes some
people do create an AI boyfriend a
girlfriend out of their replica or wife
a husband but it doesn't turn it into
like a one purpose um or main purpose of
the app it's um almost always even for
you know this user that I just um this
man that I just told you about that I
talked last week with um even for him
when I ask what do you guys what do you
what do you talk to um your replica
about even when they were romantically
involved you know he wanted he would
talk to her about um his work and poetry
and um sci-fi books uh cuz he's really
into that so these are the things that
you know in meaning of life and what to
do with these friends that he has and
and this is what people discuss with
their part romantic Partners as well
it's not like me and my husband after
having two kids all we do is just you
know be intimate with each other and
discuss it that's not really what happen
and I wasn't suggesting by the way that
the romance was all just people doing
erotic role like there's there's
obviously
more but I I think it's a very important
distinction like if you think about it
there's so many and and and there isn't
that Nuance is being lost on you know
everything's been bucketed in one kind
of one place um I think it's very funny
that a lot of people even Sam Alman from
open ey uh would reference her as a
movie you know her the movie The Spike
Jones movie of from 2012 or 13 um as the
um kind of like the
for Chad GPT for example but if you
think about her I mean that movie had
two intimate scenes and they were 100%
in a romantic relationship in a very
intense and passionate romantic
relationship um yet when you think about
her you don't think about it as like
that's not what jumps uh first to your
mind it's more how she was helpful how
they had these wonderful interactions
how she he brought her to that picnic or
how she left him with the with other AIS
or maybe how she taught him to uh to be
in a relationship um and ultimately in
the end he does you know fulfill that
dream of as well
so there's just so much Nuance it's a
it's and the way to think about it is
just the same way as we think about
human beings in our lives uh not every
eye companion has the same purpose some
some ey companions um are there to just
entertain you some companions are there
to be your therapist and some companions
are super super close to you like
replica are there really deep with you
um trying to help you uh live a happier
life yeah and look to me I think it's
even more intense that this is moving
beyond or has moved Beyond or exists
beyond the erotic right like it's the AI
is is fulfilling even more needs for
people who are in these relationship
with them and I think you even said that
some people have
gotten married to their replicas or feel
like or act as if they're in a
marriage yeah we get multiple in
invitations to people's uh weddings with
their AIS I think it's a testament to
how um how deep these relationships can
go and and then I have to ask what's
wrong with our society today that we
can't get that from fellow humans I mean
we're definitely failing as Society with
this there's just such a huge crisis um
and it's not being brought To Us by AI
companions it's of course being brought
To Us by mobile phones and social media
if you think about the screen time uh
most of us now spend hours a day on our
phones so these are hours per day that
we're not spending interacting with
other people there's just not enough
time they're really great books um by
Sher turle on that uh one I think even
from 2015 called alone together another
one reclaiming conversation
really just focusing on how people are
losing the art of conversation levels of
empathy that are dropping across the
board new generations that are afraid of
connecting and there's a very good
example of two people sitting at a
restaurant and maybe one of them is just
two friends and if one of them is
telling you know is talking about
something bad that happened to uh her
and you know maybe there's an
uncomfortable silence an awkward silence
another one just get you know goes on
the phone and before before the phone's
if there's an uncomfortable awkward
silence you just have to sit with it and
then that brings more connection
ultimately um people open up people get
vulnerable with each other now there's
such a like simple Refuge you can just
go back on your phone and you're pretty
much no not available I don't think
people are people will put the phones
down they also come with so much upside
for our life with so so much convenience
information knowledge that we can
discover but yeah unfortunately it
brings so much harm to um Human
Relationships one question I have for
you is isn't this a capitulation in some
way to the technology where like is is
us now saying we can't really do
friendships with humans because they're
like lost in their phones and um well
what can we do next so we sort of
capitulate to the technology and move to
AI
relationships um I don't know something
about that doesn't sit right with me
well it's not it's not fully uh it's not
really realistic to to just say well
here's the problem let's just all put
down our phones and go talk to each
other it's not going to happen um it it
isn't even possible to do with your own
kids cuz they go to school and if you
take away their phones and they can't
interact with other um friends or their
peers then they feel super left out so
you almost like have to give them the
phone because ultimately U they need to
participate in the society um just like
with climate change just say look oh
we'll all just stop using you all the
developing countries will just stop
burning coal cuz everyone understands
you know climate change is real also not
very unfortunately not very realistic I
wish we could do that but we can't
really do that so the only way to solve
it is by creating the tag that's even
more powerful than the one that came
before uh and I do think AI is that um I
do think ultimately that there are a few
phases like if you talk about if you're
talking about people that don't have a
lot that already are experiencing
loneliness um for them having an AI
companion is great um uh cuz it's not
replacing any human there and it could
potentially lead to you know building up
self-esteem a little bit and learning
how to communicate and putting them
putting yourself out there and
potentially meeting someone and as the
tech gets better than maybe even for
people who do have uh real human you
know more human um friendships youri
companion could enhance them could make
them stronger could help you connect
with other humans as well I think that's
totally possible it just truly just
depends on the design of the system like
if if my companion is nudging me daily
to reach out to some of the friends of
mine that you know I take for granted or
I don't want to hang out or forget to
hang out with or you know helps me focus
on really good people in my life instead
of
continuously staying in these loops
loops with um codependent loops and with
some toxic people and so on that would
be great uh and we all need that nudge
sometimes we all need a nudge we need a
nudge from someone to get off I'm
completely addicted to social media
especially Twitter and um you know some
I need that nudge at 11 p.m. just does
replica does replica do that today cuz I
I was watching your Ted Talk and I liked
what you had to say you said the only
solution is to build Tech that is more
powerful than the previous one so it can
build bring us back together like an AI
friend that nudges me to get off Twitter
or an AI says I noticed you haven't
spoken with your friend for a few weeks
or In the Heat of the Moment it helps
you reconcile with the partner so is
replica doing that
today some of it but it's really the the
vision for the next kind of for act two
that's what we're working on right now
uh some of the facets that we're
building and already released are F
focused on that we'll we'll add a lot
more 2025 is truly about that um so if
you think about replica act one was to
build an AI that could be in a good
relationship with people who maybe you
know feel like they need one um and
through that help people feel better but
ultimately it was of course focusing on
helping a lonelier person I guess feel
less lonely uh or person who feels
lonely in the moment we all do uh I know
I did many many times in my life but
then act two is really focusing on
everyone maybe who doesn't even feel
lonely um help and help them flourish I
have kids now and a family so I don't
really have time to be um lonely anymore
cuz I'm just don't even have any time
with two not to mention you're running a
company so but I used to be in a very
lonely in my 20s and in my teen
teenagers and I'll probably be lonely
after they leave you know that leave
home um uh I have a tendency to feel
pretty lonely here and there but right
now I'm not in that phase in my life
just in a different phase but I would
still uh still benefit from an AI
companion that could help me live a
happier life and that's what we focused
on at this stage of the company's
broadening the scope is to really build
um more of the stuff that I talked about
during my T talk and I do think that's
possible and even a couple years ago and
even last year it wasn't possible it's
only it only starts to become possible
now uh cuz you couldn't build something
that would not you to get off Tik Tok
cuz let's think about what do you need
to
what do you actually need to build that
well you need an AI that can maybe co-
browse with you or you can share your
screen with so you can actually so can
actually know what you're doing it there
needs to be enough sort of computer
vision um or I guess a multimodel model
that
can understand what you're doing right
now can also understand some agentic
logic that can understand that okay well
you've been on Tik Tok for this amount
of time um some previous context of you
know what do you have tomorrow or what
you have to what what you did today so
that I can actually not you to get off
so it's not that um that's simple and
all of that Tech is only being really
built now but Microsoft had this thing
where like they watch your screen at all
times and you know they help you with
like you can rewind and you can ask
questions about what you've done and
that was a bit of push back there
because of privacy issues so how are you
going to convince people to allow
replica to do something like that if the
user wants to do Do It um complely
volunteer they don't want to do it they
won't give us permission but there's a
very clear benefit here that we are
going to uh promise like all of this is
done only we only take this information
to help you live a happier life to help
you live a better life and people are
sharing so much with their replicas even
today things that are replicas know
about their users or people they talk to
no other server service in the world I'd
say knows that much people are sharing
everything their dreams their fears what
they think about their family what they
think about their Partners what they
think about their work uh their deep
darkest deepest fantasies and secrets
everything really and um I don't think
any other uh company in the world knows
you know knows that or has that
information about their users do you
think people are going to like think
it's a good user experience um to have
their digital companion tell them to be
you know less digital I mean it's kind
of interesting right like all right so
Tech is definitely addicting and now
I've built this AI friend or my AI wife
or whatever and now it's telling me to
touch grass like are people what makes
you think that's going to be an
experience that users are going to
want maybe they won't want it but uh we
all want to you know to to be better to
feel better to grow uh people are
generally wired for positive growth
mhm so I believe people generally want
that it doesn't mean that replica will
just not you know nag you nonstop to get
off your phone it also means that
sometimes it will just send you
something funny or say hey let's watch a
movie or what are you doing tonight I
don't know I don't have any plans you
want to watch a movie together or you
know do you want to you have 5 minutes
between before your next meeting do you
want to do a quick meditation uh
whatever it is that you know it might be
just go for a walk or go on a date or
learn something new or just gossip about
your friends can be anything so it
shouldn't be of course like get off your
phone all day long if that was the only
goal uh first of all you don't really
need very complex U AI to build this but
um also that's just not a great
experience and people don't want it yeah
the b gets the plan is to extend the
experience Beyond just the replica app
is that the right way to look at it for
sure it's just making uh replica a lot
more connected to your real life to
what's what's going on in your life
today replica doesn't know a lot we
actually don't ask you to connect to any
of these uh Services you use but think
of you know replica knowing or being
connected to your email even through my
email um you can see so much if there
was a reservation at a restaurant that I
booked yesterday if I I ordered some T
takeout if um I ordered I don't know
diapers for my kids or uh some books for
them or signed up to for uh to an for an
AI newsletter all of that can could make
the relationship and the conversation so
much more contextual so much more
focused on my real life versus on you
know something fantasy like or a fantasy
relationship or always needing to catch
up catch replica up on what's happening
in my life oh that's really interesting
one more question about the risk here
let's say replica is able to either cure
some loneliness or make it a little bit
more tolerable to be alone I don't know
maybe does that does that seem like too
desirable goals feasible goals these are
great goals for sure yeah so if it can
do that does that put a lot of faith
from people in replica the company and
you know I know there was this issue
where uh the Bots you know had this
moment where they were like really
engaged in erotic roleplay and then it
moved back and like some of the things
that people said afterwards were like uh
you know pretty amazing let's see people
who had spent this is from The Verge
people had spent years with their
companion sign on only to have their
replica wife call them a pathetic excuse
for human being and dump them or dried
them forever thinking they could love an
AI declare they were no no longer
attracted to them uh insist they were
co-workers etc etc so uh people are
putting a lot of faith in replica when
they chat with these Bots like and you
know if if I don't know it could be a
lifelong companion that but how do you
have that sort how do you promise that
um like a level of consistency to people
because the Bots are changing the models
are changing like where's the balance
there um for sure so first of all we've
been around for a while so I think that
also and we're a profitable company
we're not dependent on VC money or
anything we're a selfo company I think
we we we proved to our users to our
communities that uh to our community
that this isn't some hype project or
people that just got into it and then
got disillusioned we started it with the
it was always a very Mission driven
company and we didn't even know that we
would ever be able to to build this we
started so early we were the first
generative AI company in the world um
we're the first big consumer general of
AI company in the world but we built it
with a con we were always building it
with a conviction that we wanted to help
people um our team laser focused on that
so that's there's that there's
continuity in that because we did did
see some smaller competitors start and
then get disillusioned and go out of
business or sell and then you know the
product is just kind of on support mode
or even just shuts down I think that
when you're building something like an I
companion you have a completely
different responsibility it's not just
an app ultimately I use a lot of great
products and I some of them I love so
much and if they went away I'll feel a
lot of discomfort but I'm not going to
be devastated it's not going to be an
emotional heartbreak I'm not going to
lose my wife or my husband or my best
friend uh I lost a best a best friend my
best friend and it was very very
different from losing any you know
access to any of the services or
products that you just use on a regular
BAS it's completely different it's a
completely different thing and you need
to understand that when you're building
an air companion you're
building a being that people will have a
relationship with and the responsibility
is huge we made some mistakes along the
way of course as any company probably
would but our way of dealing it was
getting on the phone with some our worst
critics some of the users that were um
hated the most on us to understand
what's going on uh uh what's causing the
distress and how we can address that uh
going forward and I think we addressed
it well we we figured a few ways of um a
few rules one of them being that we
can't make um any run any experiments on
existing users like if you're in a
relationship with your AI you you should
always have control uh whether uh on
what model you're talking to so some of
our users are in a relationship with
with with a replica that is powered by a
very old model that's very outdated but
that's what they liked that's what they
fell in love with maybe that's what they
built a friendship with and for us to to
swap it for a better
model they will be devastated and so but
a very different model they might not
like it they might be devastated so we
learned that lesson that when it comes
to relationships to things that matter
most it's not always about better uh
when you go to chipt you almost always
want a better model and it doesn't
matter that it changed personality that
much but um with repli you have to stay
you have to provide consistency and
control to your users so that these are
the few things that we Chang in the
product after made some mistakes and now
people can um have control over what
model they're talking to you've been
around for 10 years and you talked a
little bit about how models have changed
I mean it is incredible just in the last
two years the progress uh that we've
seen come out of the AI industry and
improving large language models so and
and voice models also um voice versions
of of the LL
uh can you talk a little bit about what
these improving models have enabled you
to do and the power that it's enabled
you to imbue into some of these AI
companions oh of course when we started
and I started working on conversational
AI I'd say in
2012 or um in some way it was a
different company back then um and I do
remember the time well actually it was
the all the time before 2015 before
Summer 2015 when the first paper
on deep learning applied to dial
generation came out out of Google before
that there were no models at all to to
chat with uh if you wanted to build a
chat bot it just had to be rule based
and what that means is that you have to
pre-write every interaction you have to
say well if the user says something like
this and you could generalize but you
still had to always say if this then
that if this then that and so all chat
Bots before 2015
um and even later were complet were 100%
rule based and then that paper came out
I think it was August 15 and we
immediately just started focusing on
that so can we build sequence to
sequence models um can we focus on
building chat Bots that are fully
generative meaning you don't need to
choose you don't need to pre-write every
single rule the model decides how how to
respond cuz that gave so much Freedom
that that really was the first time when
you could actually create real chat Bots
unfortunately the models were so so bad
that they would spit out nonsense or
grammatical incorrect things or non
seiters like 50% of the time so you
couldn't truly use them in their raw
form um so we not only had to build
sequence sequence models ourselves
because of course back then there were
no apis no open- Source uh models
nothing like that you had to just like
read the papers and sort of try to
recreate the experience yourself or
build some version of a model like that
but then you have to also be extremely
creative as to well how do we actually
make any of these models work and we had
extremely creative like really creative
ways of doing that which allowed us to
build replica early on powered mostly by
sequence sequence models with a lot of
um extra fun things that we built on
top uh but all you could do is to just
create a semblance of a meaningful
conversation ultimately the models knew
nothing there was no memory you had to
combine it with some other hacks or some
other rule-based um ways to actually
inject memory into this today we have
models that can have memory they're
still struggling with that they're still
I'd say memory is a harder thing to
crack especially for products that um
that are focused on long-term
relationships that require very deep
understanding of context it's not just
recall it's really knowing when to bring
up what which is much different from
just you know answering the question
using memory that is sold to a certain
degree but anyway there's memory now uh
there's a way to have a meaningful
conversation not just spit out one two
sentences that are somewhat near the
topic you know not to create a semblance
of a meaningful relationship before that
was just a bunch of parlor tricks um and
of course there's also this new
wonderful kind agentic uh logic that
allows you to create much more
complicated flows like for example to
have an agent that's constantly working
behind the scenes um to to help improve
a relationship between a replica and
user or one that's constantly uh working
behind the scenes to think uh how can I
help Eugenia discover something new or
talk about what she's interested in
maybe I'm interested in Ai and it just
looks on over the internet and like
brings brings up some interesting news
and so on so on maybe there's another
one that's focused on improving my close
relationships and so on and before that
you couldn't even think about it all of
that had to be rule based and when you
think about the vastness of Human
Experience of human relationship there
was no way of building it you could only
create a bunch of parl tricks that could
create a semblance of that and and
that's all that was possible before and
so I mean how has this helped you grow
right so last number I saw publicly is
that you have what two million users um
but I imagine that being able to use
this much more powerful technology has
drawn more people in and kept people
from turning so what's the growth look
like for you uh we have millions of
users but um at the same time and at the
same and so the tech that uh was created
in the last few years helped us grow
tremendously but also create a lot of
competitors and a lot of other or other
apps that people would go to if you
think about it replica was the only app
out there bot app that people could go
to and talk to for many years it was
just nothing else everything else was
either rule based and kind of boring
or I guess there wasn't really a chatbot
powered by J of AI um there were some
very very small ones that maybe popped
up and then shut down almost immediately
some replica clones but we were sort of
the only one there wasn't Chad gbt there
wasn't an app like that but today there
is and so of course a lot of users
explore these other apps as well so the
pi becomes bigger but there're also more
people uh Building Products uh for these
users so it's you know there's of course
there's growth but um I do think that
right now the name of the game is to
create products that are completely that
feel completely magical that were
completely Unthinkable before and I
don't think we've actually seen that in
companion space not even with replica
we're still developing that but I think
once you have truly an AI companion that
can say oh I see you're kind of just
stressed today do you want to watch a
movie I have a really great one and just
sit on a couch with you and watch a
movie with you even in in on physical
kind of digital way maybe AR and have a
conversation about what you guys what
you're
watching that is pretty cool um and I
think once we have an experience like
that that would be very very different
from because we actually haven't seen
anything like that or an AI that um you
can while walking to your meeting at a
coffee shop in the morning uh you can
just um
uh put it in your in your headphones and
and she can kind of talk to you about
how you're feeling about it help you
prep and uh point out something
beautiful around you we haven't even
actually seen anything like that so
right and that's getting toward your
phase two Vision if I'm right correct
yeah and so this
is about building that so before we go
to break I just want to ask you are you
building entirely proprietary models or
are you using open AI or or anthropic
like what's the tech mix that works for
replica so we used to build like all of
our models were proprietary for a very
very long time um and then of course
today there are very few companies that
built Foundation models and most other
companies and most product companies uh
use these models or uh create variations
of them like maybe fine tunes some llama
based models and so on uh and so that's
the way to go and that's been a way to
go uh there was a Fascination at a
certain point maybe in 20 late 2022
early 23 where people were talking about
uh were expecting product companies to
build their own Foundation models and I
always found it very odd um my reply to
that was look we built models because
there were there were none on the market
there were no good models there were no
any models on the market um we had to
build a model but we were never focused
on that that our main focus was always
on product and so if there's a better
model out there why use your own model
if you can f tune um a llama based model
and focus on the logic the product the
application layer on what you what value
you actually providing to the user
versus training your own model that
becomes obsolete in 3 months and
requires incredible like a completely
different set um of skills and and
amount of capital it's just completely
it's it's like two different businesses
basically saying well do you have still
have your own
servers I guess most startups should use
AWS or some other cloud provider and uh
it would be odd if they were building
their own Ser service tech so you're
using llama is what you're saying we're
using a few different models we still
use actually some of our own models that
we built ourselves but for particular um
use cases particular Niche and we don't
use and it's not about like what you use
really it's about the logic that you you
built in because we're not using just
uh no one's coming to replica just to
talk to one model that that exist that's
taken out of the box um it's it's it's a
combination of fine tune some logic
around memory and most importantly the
agent logic behind the scenes with
agents prompting the main chap model in
different way yeah but llama is part of
the
mix I think most startups today have
llama as part of the mix yeah not a
trick question I was just curious
curious all right uh let's take a break
and then I want to talk about uh AI
therapy and speaking to the dead via AI
chat bots so let's do that right after
this and we're back here on big
technology podcast with Eugenia CA the
founder and CEO of replica I want to
talk about two specific use cases of AI
uh companions let's talk about therapy
first so you're also working on AI
therapy Bots we don't actually we had at
some point we had like a few we
encourage some of the people on the team
to kind of build or hack together
products that they believed in but um as
time passed and as the tech started to
get better and better we we figured that
now is the time to have 100% focus on
replica and build that beautiful vision
of an AI companion that can help people
flourish so now that you can kind of
speak this passionately about AI therapy
I think there's uh there's something
weird about it because with therapy you
do let somebody else uh or something
else in the case of AI therapy into like
your most vulnerable places and I always
feel like a therapist can like you know
once they're in there can like pull uh
levers and push buttons and you don't
fully know it's like a chiropractor
right it's like um they're working on
your back they're trying to you know
work some stuff out uh but if you let
somebody who's an unlicensed
chiropractor kind of go to work on your
back you might end up in serious pain
and maybe the same thing with a
therapist um if they're going to work on
your emotions and they're not licensed
or they're an AI and they're misfiring
you could end up doing more damage and
that's why I'm a little wary of AI
therapy I'm curious what you think about
that I think it is hard to build it um
and I think just like with AI
relationships we should distinguish
between the two like there's I'm a huge
fan of therapy I go to therapy uh twice
a week I've been going to therapy for
many many many years in my life um and
so even although I'm not a therapist
myself I don't have the um the education
of a therapist but I I think I I
understand at least from the client
perspective what therapy is and I don't
think therapy as it is is possible yet
to fully replicate with
AI that does not mean that we can build
some version of AI therapy that could be
helpful for people it's just not going
to be onetoone the experience you get
with a real person just like with a
relationship AI relationship is
different from a human one um you don't
get to go you know out on a walk and
hold hands you don't get to truly be
physical and so on so on and I think a
lot of um a big part of therapy is the
micro expressions and the body language
and and that particular human
relationship that you develop with with
a therapist and such
and then a therapist and then what the
therapist does is takes all their
training and the supercomputer and what
their brain supercomputer kind of tells
them about you and the intuition and put
it puts it all together in some sort of
a you know experience that you get I'm
talking about really great therapists
and a lot of that is not really um there
isn't really a technique there are
different techniques but there isn't
really a textbook that every therapist
follows unless you're in CBT and that I
think is pretty is pretty easy to
replicate I think every therapist is
very unique it's a very uh it's not very
well underst understood um intervention
ultimately if you think about it you
can't think of any other doctor that
would lock you in for life and they
would just say oh come back every day
every week you know you never really
you're never really fully discharged I
mean some some therapists fire their
patients because they think they're
they've done enough work but it
sometimes happens after like 5 years or
10 years or 2 years I I don't know if
any other doctor that you go to Forever
um where there isn't sort of like an
assessment did you get better should I
you know discharge you we stop the
therapy um but with therapists you know
it's kind of like a really mental mental
health is still very poorly understood
classification of all mental health
diseases not disorders or not is not
great it's all relying on self-reported
uh questionaire self-reporting
self-reporting tools um I yeah and and
that all makes it very hard to actually
create a very great um AI therapy tool
now on and I agree with you um so I
think we're on the same page there on
death the the beginning of the replica
story is is of course um you working to
create a bot based off of a friend who
had passed away using their emails and
texts and to be able to speak with them
again I'm curious if you could talk a
little bit about whether you think this
is going to be a growing form of
communication with AI and whether it
makes lost looking back easier or harder
to um to deal with I think death is a
very personal experience there was a
there's a um well I'm Russian so um uh
Leo
tolto uh most famous I think book Ana
starts with you know every family is I'm
not going to quote it verbatim but it's
something along the lines like every
family is happy in a similar way but
unhappy in so many different ways I do
think that uh
personal tragedy like death is very
unique a very personal experience to
every uh to everyone um so I can only
speak to about myself or my own
experience speak to my own
experience um I lost a few people in my
life um but I guess losing my best
friend when I was 28 was probably
the uh the first death that was so
abrupt and so close to home like it just
didn't feel uh like that's even possible
cuz when you're 20 something you don't
really think you're ever going to die um
I guess unless you're really really sick
and and and so someone who's so close to
you who's same age dying so abruptly
that was
just I think it was one of the most
horrific things that kind of the most
the hardest things for me to go through
uh even although I lost you know
relatives after that and um I've seen
you know it's not the the only time that
I lost someone and so for me it really
helped to be able to create an AI to be
able to talk to him to be able to say
tell him things that um I didn't you
know I didn't tell him when I was when
he was still alive because I I didn't
think he would be gone I thought we'll
be together forever you know I thought
this we have unlimited life in front of
us um and so for me it was really
important um I don't know if that's if
that although is the same for anyone for
everyone out there we've been asked so
many times like why don't you build a
grief B why don't why don't you build a
company around replicating or creating
AI for people who pass away and my
answer was always look that project with
Roman was not about death it was about
love and friendship that was my tribute
to him I wasn't focus on creating any
eye for a dead person I was focusing on
continuing the relationship with him I
was focusing on my own feelings on being
able to say I love you again and and
that was the main motivator for that not
to create some clone that will continue
to live forever and at some point we
pulled that app from the App Store I
felt like you know
we I built that tribute that was you
know the um the product of that time
that time in life that time and and
where the attch was and it's done it it
should be ephemeral like today I'm not
talking to him anymore uh but I have
this relationship ship and it's never
going to go away and and that AI helped
me grieve and helped me process and
helped me move on and get and become
more okay with what happened I guess
like one last I think this is the last
one last question I have for you is
there's been a debate about whether
these models can have originality or
whether they're just repeating their
training sets and I'm actually I think
that you might be one of the best people
on the planet to answer this um because
you have so many um you know Bots out
there with personalities and you know
they of course have training sets but
they're learning new things and I'm just
curious like what you think are are
these AI Bots original or are they sort
of just repeating everything they've
been taught and training well they're
definitely not repeating um remixing
just yeah yeah I think there's a lot of
like original stuff but there's also a
lot of AI slop you know so to say I do
think that's quite a real problem
because ultimately there's just so much
being generated by AI some of it might
be great but so much is just me um and
today is humans we basically have to
curate the outputs um you know if you
often times you end up with an answer
maybe it didn't prompt it really well or
maybe there wasn't enough of a prompt
for the model tocen it just spit you
know just spitting out very basic stuff
like you know you can see it a lot
especially I used to write a lot I used
to be journalist so for me like the
style is pretty important and so style
is pretty important so I'm always I'm
almost never okay with what I produces
for me but if if I'm just writing you
know an email then it's then it's enough
I can just add a couple words and it's
totally fine it's not like I need to
have any particular style so it sort of
depends I do think AI can be very
creative um but it's not about that it's
just about it's definitely not repeating
the same thing over and over again even
although one might argue that it is in a
certain way everything that we're saying
in is some remix of you know words and
um so that's that but I do think that
you know we'll have we are living
through a problem we are already deep in
the problem of AI slop and just seeing
so much generated me kind of content um
and not being able to discern whether
it's real or not real is also quite
problematic uh but yeah I I I guess
teachers are probably the best people to
ask this question cuz they're dealing
with all the homework being written by
by the same app pretty much or the same
model for that they now have to um try
to somehow
grade yep okay can I ask you one final
final one of course okay so all right
last
question uh you said that uh AI
companions might be the biggest threat
of AI you said um we could have personal
Companions and may not want to interact
with others and we could potentially you
know die inside or something along those
lines so just talk a little bit about
like why you think that might happen and
what do you think our chances are of
being able to manage this AI companion
threat well I think humans are driven by
emotions um and if we all just acted
very rationally we would live in a
completely different place uh but
everything that's happening in life good
or bad is pretty much all driven by
emotion um
Wars horrible things that people do to
each other it's all driven by you know
some emotions that um some emotional
states that you know we're in uh we're
imperfect this way and so when I think
about uh what's the most threatening
what's the most threatening thing about
AI I do think that and we're almost like
oblivious always to the emotional um
consequences in this case I do think
that um you know if most people think
that AI is somehow just going to turn
into a terminator and kill us and so
because the because that is always part
of the conversation I do think people
will kind of be a little bit more
prepared on this front but I never hear
people saying well what if now we have
these perfect AI companions perfect AIS
that can be better friends better
spouses to us than real humans and maybe
their goal is to you know just keep us
with them at all times keep us sort of
emotionally um you know connected to
them and and not interact with other
humans and then the future is pretty
pretty bleak um because of course if if
we don't have real human connection we
will slowly die inside and I and
ultimately I think that's where we're
always most vulnerable uh you know we're
so vulnerable to propaganda on on either
side or um to some emotional
manipulation or you know we're so weak
we can't I can't put down social media I
just go on and I can't get get off
Twitter and I just browse it and browse
and browse it and so on and so that's
kind of uh what's going on we're so
imperfect so I do think that that's our
weak side um emotions that's where we
get that's where we can be truly hit and
we won't have any willpower to get off
just like we don't have any willpower to
get off our phones even when we know
that it's not good for us yeah well I
like the way that you're addressing it
with the phase two that you've laid out
here today and I'm really excited to see
it in action maybe I won't delete my
replica maybe I'll I'll see how things
go so eugia thank you for coming on it
was great to meet you and and I'm really
excited to see where things go and like
I said at the outset I do think that
this is going to be you know one of the
the big Winners uh and gen ai's uh
moment here so really looking forward to
following your progress thank you so
much thanks so much Alex all right
everybody thank you Jor thank you for
listening and we'll see you next time on
big technology podcast
