❯ OpenAI prices GPT-6 Astra at $50 per million output tokens, matching Claude Fable 5.1 exactly

price parityOpenAI set standard API pricing for GPT-6 Astra at $10 per million input tokens and $50 per million output — 2.5x GPT-5.6 Sol’s current promotional rate and identical to Anthropic’s Claude Fable 5.1, released three days earlier. Low-latency fast mode doubles both to $20 and $100; Batch and Flex run at 50% of standard.

training scaleOpenAI says Astra was built on the largest training run in company history, using more than 100,000 GPUs at its Stargate site in Texas, according to Axios, and that GPT-5.6 Sol helped supervise that training. It is the first time OpenAI has put a GPU count on a single run publicly, and it explains why the price stepped up 2.5x.

rollout orderWho gets it, and when, is equally telling: first only organizations in the Daybreak Access program plus restricted cybersecurity customers, then Plus, Pro, Business and Enterprise over the following days, with the API and AWS after that. Altman posted three times to reassure waiting users, and ChatGPT Work and Codex subscribers get usage credits for each day without Astra. The only cloud partner named in the official messaging is AWS.

a price bandTwo labs landing on the same number is not coincidence — the frontier price band is now fixed. For applications billing by token, switching vendors saves nothing, so comparison falls back to tokens consumed per task. The actual per-task invoice teams measure over the coming weeks will replace leaderboards as the real basis for selection.

▪ SIGNALTwo flagships priced identically means frontier models now sell as a commodity — the difference only shows up on the bill.
