Ultrafast
An inference tier introduced by OpenAI for GPT-6 Astra, designed to significantly increase token generation throughput while preserving the model's full capabilities. It targets latency-sensitive real-time interaction and high-concurrency application scenarios.
Timeline (last 90 days)
Ultrafast is an AI tool mentioned in a tweet, and users commented that it is extremely fast and makes them unwilling to go back to the old way of using things.
Amp has entered a partnership with OpenAI, integrating multiple OpenAI models including GPT-6 Astra, Ultrafast, and GPT-Live-1, and supports connecting account systems through Sign in with ChatGPT.
Ultrafast is a new premium speed tier where models can be up to 8 times faster, at the cost of 6 times the price.
OpenAI has launched a premium speed tier called Ultrafast, which achieves up to 8x faster token generation in Codex and up to 6x faster speeds via the API.
The officially advertised 7x+ speedup primarily refers to TPS (tokens per second), i.e., throughput improvement in the generation phase, and does not necessarily mean an equivalent reduction in TTFT.
An official demo showcasing Ultrafast with a racing game dynamically generating sprite images demonstrates that Ultrafast requests complete output first while regular generation tasks are still running
Information such as Ultrafast's pricing, whether the 7x speedup holds across all task types and context lengths, and independent benchmark evidence supporting the claim of uncompromised intelligence has not yet been made public
For latency-sensitive scenarios (game development, real-time content creation, interactive applications), Ultrafast's instant generation capability has clear application potential
OpenAI has not disclosed the specific technical approach behind Ultrafast.
In API scenarios, Ultrafast's token generation speed is more than 7 times that of the Standard Tier.
