ChatGPT: AI lands in everyone's browser
In one sentence OpenAI launches ChatGPT, a free conversational interface in research preview, built on a GPT-3.5-series model trained with RLHF. It crosses one million users in five days.
OpenAI puts a website online, chat.openai.com, where anyone can talk to an AI. It's free, it speaks any major language, and it answers like a person.
The model underneath comes from the GPT-3.5 series, fine-tuned for conversation and instruction-following. It's not the first conversational AI, but it's the first one normal people try and tell their friends about.
On December 5 Sam Altman announces it has crossed one million users. From those days on, every conversation about AI changes tone: it stops being "research" and becomes "I use it too".
