We've made some improvements that improve usage on the long tail for power users of Astra when logged in with your ChatGPT account.
No change in quality and a pure win that on the long tail can result in up to 3-4X less usage being drawn from the subscription.
To calibrate you all on which reasoning effort to use for Astra, know that GPT-6 Astra on low performs better than GPT-5.6 Sol on high.
If you were using high reasoning efforts with Sol and were happy, I suggest you move down to low or medium for Astra.
GPT-6 Astra is now available to all Pro, Enterprise, and Business Premium users in ChatGPT Work and Codex. It's also live in the API.
It might take a few days to roll out to our Plus and Business users. Thank you for your patience.
