OpenAI has begun rolling GPT-6 Astra to ChatGPT Plus subscribers on the $20-a-month plan, after first opening the flagship model to Pro, Business Premium, and Enterprise accounts. Early Plus access is landing in ChatGPT Work rather than the everyday Chat picker, and it is included in existing paid allowances rather than sold as a separate SKU.

GPT-6 Astra reaches $20 Plus

OpenAI is rolling its flagship model to ChatGPT Plus. Early Plus access is landing in Work and Codex, not in everyday Chat, and it counts against existing plan limits.

Columns are scaled 1:2. OpenAI estimates Plus Astra at about half Sol’s local-message rate; extra credits are sold after the cap.

What Plus gets

GPT-6 Astra is included on the $20 plan in ChatGPT Work and Codex, with no separate model fee. Some users say it stays on long tool-call workflows more cleanly than Sol.

What Plus does not get

GPT-6 Pro in standard Chat is for Pro, Business, and Enterprise. Plus still sees GPT-5.6 Sol there, and Astra’s tighter 5–45 message window can burn down on a few long tasks.

Plan line

Plus gets Astra the agent, not Astra the everyday Chat model.

Work and Codex share the plan allowance. GPT-6 Pro in Chat remains on $100/$200 Pro and higher business tiers. Free and Go are not in the Astra rollout. API access is sold separately as gpt-6-astra at $10 / $50 per million tokens.
