Chai AI

“The number one problem for users in AI is this. All the AI is being generated by middle-aged men in Silicon Valley, right? That's all the content. You're interacting with this AI. You're speaking to it for 90 minutes on average. It's being trained by a middle-…”

“I think in even 20, I think late twenty-twenty-two, was it late twenty-twenty-two or maybe early twenty-twenty-three, Chai was like the number one AI app in the app store. So we would have something like a 100,000 daily active users.”

“Users grew by a factor of three last year. Revenue over doubled.”

“I was the only person who'd invested. I'd invested maybe two million pounds in the business, and, you know, from that we were able to build this thing, get to say a 100,000 daily active users”

“They launched it. I think they launched it at least nine months after us.”

“Right now we're spending 40,000 dollars a day on user acquisition. That's still only half of what, like, Character AI or Talkie may be spending.”

“The thing I'm just trying to share here is there's one surprising thing about humans is their preferences are pretty correlated. What you find funny and entertaining, I find funny and entertaining, and he finds funny and entertaining. There might be degrees of…”

“With Chai, let's say a typical user session is 90 minutes, which is like, you know, is very, very long. For comparison, let's say the average session length on TikTok is 70 minutes. So people are spending a lot of time, and in that time they're able to send, s…”

“We've paid out over a 100,000 dollars to model creators”

“The realization that developers and software engineers aren't interested in building this sort of AI, but the consumers are. Right. And rather than me trying to guess every day, like what's the right bot to submit to the platform? Why don't we just create the …”

“We saw that it didn't really make a difference. Like, if they were submitting models at a certain rate, if you pay them a bunch of money, they didn't change the rate.”

“And it was something like only 10 or 15% of users even clicked the button to like, they wanted to engage the audio, and they would only use it for 10 or 15% of the time.”

“How do you get the user an experience that is both smart and funny? Well, just 50% of the requests, you can serve them the smart model, 50% of the requests, you serve them the funny model... The eighty-twenty solution, if you just do that, you get a pretty pow…”

“The thing that AI is 10 X better at is a sort of a conversation Right? That's not intrinsically informative, but is more about an opportunity. You can say whatever you want. You're not going to get judged. If it's three AM, you don't have to wait for your frie…”

“Every day we're able to, I mean, we evaluate between 20 and 50 models, LLMs, every single day, right? So even though we've got, only got a team of, say, five AI researchers, they're able to iterate a huge quantity of LLMs, right? So our team ships, let's just …”

“And so we were able to get that 30 day feedback loop all the way down to something like three hours.”

“You can try and do, like, a routing thing where you say, for a user, given user requests, we're going to try and predict which of these end models that users enjoy the most. That turns out to be pretty expensive and not a huge source of, like, edge or improvem…”

“Chai has never done streaming. Because if you stream, you're unable to do rejection sampling.”

“There must exist a platform where a small team can produce an AI for a unique purpose and they can iterate and build the best thing for that.”

“We think it takes about 5000 completions to get an accurate signal.”
