OpenAI may widen access to an Ultrafast API mode after DevDay

TestingCatalog reports that OpenAI is preparing a Fast, Standard and Ultrafast selector for the Responses API Playground and may widen Ultrafast access after DevDay. The outlet says the mode has so far been limited to selected partners. The available evidence does not establish a public launch date, eligible models, pricing or whether the interface will reach every API account, so the change remains an expected rollout rather than a confirmed release.
