FourWeekMBA reported on October 31, 2026, that OpenAI’s API pricing page listed gpt-6-astra-law at $10 per million input tokens, $50 per million output tokens, and $1 per million cached input tokens. The report also quoted promotional pricing through at least December 31, 2026. Those are dated reported rates, not a complete price schedule for every type of API use.
The rates reported for Astra for Law
The three amounts FourWeekMBA reported were denominated in U.S. dollars per million tokens. The report did not identify the legal configuration’s context-length tier or give a cache-write rate. It also said the reported promotional pricing would last at least through December 31, 2026.
For a budgeting estimate, input, output, cached input and cache writes are separate billing categories. A rate for one does not supply the others, and context length can change a model’s listed rates.
How GPT-6 Astra’s listed rates differ by context
OpenAI’s API pricing page lists separate short- and long-context rates for GPT-6 Astra. At the short-context tier, the listed prices per million tokens are $10 for input, $1 for cached input, $12.50 for cache writes and $50 for output. At the long-context tier, they are $20, $2, $25 and $75, respectively. OpenAI’s API pricing
That tier distinction matters when interpreting the Astra for Law report: FourWeekMBA’s three reported amounts do not identify which context tier they apply to, and they do not include a cache-write amount. The report therefore does not provide all the rates needed to estimate a workload that uses those categories or the long-context tier.
What OpenAI announced about the configuration and API access
OpenAI describes Astra for Law as GPT-6 Astra combined with a legal search index and instructions for legal analysis and writing. It announced the configuration on September 17, 2026, saying selected law firms would initially access it through Trusted Access in ChatGPT and Codex, with API access coming soon.
