Sam Altman was also surprised that no one built ChatGPT before OpenAI: "we had the model for ChatGPT in the API for ~10 months before we made ChatGPT .. I sort of thought someone (else) was gonna just build it" (reminder: there are *many* similarly unbuilt products right now)

I remember that people definitely built chatbot interfaces on gpt-3 when it first came out

It costs too much for business to run. Although cutting edge. Its not cost effective.

The GPT-3 API is expensive. ChatGPT is free. Why would anyone but OpenAI build it?

Offering it for free at scale is challenging. Assuming 2c per avg request, 1M users/day sending avg 10 requests/day is $200K/day. That's quite the pre-seed round you need to get that going

The success of ChatGPT is achieved only because it was free to the public, it makes no sense to anyone to burn millions.

Their policies specifically prohibited it. They changed the policy right around the time it was about to be released

General-purpose chatbots were explicitly banned for most of the time GPT-3 has been available.

Apparently it cost $3M per day to run ChatGPT. Try to pitch that to any VCs lol

Sam Altman on the Paul Graham advice that saved Open AI: “Always make an API” Four years into OpenAI, Sam Altman and the team realized that they would have to build a really big company to fund the development of their increasingly capital-intensive foundation models. “We had this model called GPT-3,” Sam recalls. “I was turning up the urgency on the company to try and figure out a product, and we just couldn’t. It was cool, but it wasn’t good enough to make something that worked.” Then Sam remembered a piece of advice from Y Combinator founder Paul Graham that stuck with him: “You should always make an API. No matter what, you should make an API. Good stuff will happen.” Out of ideas for a product, the OpenAI team decided to make GPT-3 available as an API. “Maybe somebody will figure out something to do with it,” Sam thought. A few copywriting applications like Jasper and Copy AI did take off using the GPT-3 API, but OpenAI also noticed interesting behavior that eventually became a sleeper hit: “Some people — not a lot — would just chat with that thing all day,” Sam explains. “It wasn’t very good but there was clear user signal that people wanted to talk to the models. And given that that was the only thing besides copywriting that had real traction, we said, ‘Maybe this is just he product we should build.’” On November 30, 2022, ChatGPT was released to the public as a “research preview” using a model from the GPT-3.5 series. It reached over a million users in five days. Source: Khosla Ventures (Sep 2025)
