OpenAI Launches Ultrafast Mode for GPT-6.1 Sol with Up to 8x Speed

On October 9, OpenAI's official developer account announced an "Ultrafast" mode for GPT-6.1 Sol, available immediately on the API, Codex, and ChatGPT Work. The company claims the mode is up to roughly 700% faster than Sol Standard (i.e., up to about 8x), with intelligence close to Astra; Polymarket's news feed also relayed the news as "up to 700% faster."

Confirmed

Launch timing and scope: available the same day on the API, Codex, and ChatGPT Work.
Pricing: $12 per million input tokens and $60 per million output tokens on the API.
Availability: in Codex and ChatGPT Work, it is limited to Pro 500, eligible usage-based Enterprise plans, and credit-based Edu plans, with new EU data residency support.

Unconfirmed

User @patiencecave alleged that this "GPT-6.1 Sol Ultrafast launch" is actually an in-joke/meme rather than a real product release. OpenAI has not responded to the claim, and the nature of the announcement remains disputed — treat specific details as pending official confirmation.

Why it matters

If genuine, Ultrafast would dramatically boost speed while keeping intelligence near Astra levels, directly affecting model selection and cost estimates for high-throughput development scenarios; the $12/M input and $60/M output pricing is also a key parameter for developers evaluating value. Given the "meme" allegations, readers should wait for further confirmation from official channels before citing it.
