OpenAI launches GPT-6.1 Sol Ultrafast mode at $12/$60 per million tokens, with EU data residency
Overview
OpenAI says it is rolling out Ultrafast mode for GPT-6.1 Sol across the API, Codex, and ChatGPT Work, describing near-Astra intelligence at up to 8x the speed of Sol Standard.
On the API, Ultrafast is priced at $12 per million input tokens and $60 per million output tokens. OpenAI also says Ultrafast is available in all supported regions, including US and EU data residency, and that EU data residency has been added for GPT-6.1 Sol Fast and GPT-6 Luna Fast.
In Codex and ChatGPT Work, access is limited to Pro 500, eligible usage-based Enterprise, and credit-based Edu plans, and Enterprise admins must enable it. Third parties have since added support: OpenRouter says Sol Ultrafast is live on its platform, and Vercel says it added Ultrafast on AI Gateway, where developers set service_tier to ultrafast per request, including over WebSocket.
