DevDay and GPT-4 Turbo
OpenAI presented a model with a 128-thousand-token context at a third of the price, and let users assemble their own assistants without code.
Why it matters
A language model turned into a platform: not a product but an environment others build in.

Eleven days later the board removed Altman and the announced plans hung for a week. The move from model to platform proved decisive for the next two years.
