The company says the mode reaches up to 8x the speed of Sol Standard. API pricing is $12 per million input tokens and $60 per million output tokens, which OpenAI describes as 1.2x the cost of Astra. In Codex and ChatGPT Work, the announcement lists Pro 500, eligible usage-based Enterprise, and credit-based Edu plans; Enterprise admins must enable access. OpenAI says the mode is available in supported regions, including US and EU data residency support. These are company-reported claims; the announcement does not provide independent latency measurements or workload-level cost comparisons.
