OpenAI Soft-Releases GPT‑6 Astra

Simon Willison:

GPT-6 Astra is “rolling out today to a limited set of organizations and over the coming days will become available to all ChatGPT Plus, Pro, Business, and Enterprise users, as well as through the OpenAI API and AWS” — I’ve not tried it yet myself, so I don’t have a great deal to say about it yet.

It’s going to be API priced at the same rate as Claude Fable 5 and 5.1: $10/million input and $50/million output. This is clearly OpenAI’s Fable competitor, and appears to score higher than Fable on most of OpenAI’s self-reported benchmarks.
