In a video, Altman says Astra can build 10 assistants in one afternoon and advises users to keep giving it harder problems in software, science and complex simulations.

A user posts that their Astra Codex 20x plan went from 70% usage to zero in 16 minutes and asks OpenAI staff whether it is a joke.
