OpenAI announced on September 5 that it has accelerated the launch of GPT-6 Astra. This model is available to all Pro and Enterprise users, as well as Business Premium seats, within ChatGPT Work and Codex. Deployment to Plus and Business Standard seats may take several days.
Thibault Scherrer of OpenAI announced that to commemorate the early rollout, "full banked reset" rights will be distributed to all ChatGPT Plus, Pro, and Business users. These reset rights allow users to restore their usage quotas at any time after they have been exhausted. This distribution was implemented as compensation for the launch occurring earlier than originally scheduled.
