We’re introducing Pro 500, a new $500/month plan with the highest included usage of the Pro plans and access to Astra Ultrafast in ChatGPT Work and Codex. Select Ultrafast in the model picker to use a faster service tier for GPT-6 Astra. It uses your included allowance first, then your credit balance after that allowance is used.
Among Pro plans, Ultrafast is available only with Pro 500. Buying credits on Pro 100 or Pro 200 does not unlock it. Pro 500 subscriptions are available through ChatGPT on the web at launch.
