OpenAI launched GPT-6.1 Sol Ultrafast across API, Codex, and ChatGPT Work, priced at $12 input/$60 output per million tokens.

Telegram messages attributing the information to OpenAI’s developer communications report the October 8 rollout of Ultrafast mode (超快模式) for GPT-6.1 Sol. The identified access points are the API, Codex, and ChatGPT Work.

The reported pricing is $12 per million input tokens and $60 per million output tokens. These are separate input and output usage rates; the supplied message does not provide cached-input pricing, batch discounts, or subscription entitlements.

Another supplied message attributes to OpenAI developers a claim of up to eight times the speed of Sol Standard, with intelligence described as approaching Astra. No benchmark methodology, absolute token-generation rate, workload conditions, or independent comparison is supplied, so the performance description remains a vendor claim.
