OpenAI reportedly wiring "Ultrafast" service tier into everything ahead of DevDay
VraserX · x · 2026-09-26
An unverified leak suggests OpenAI is integrating an "Ultrafast" service tier across its stack before DevDay:
- The Agents API can now be set to ultrafast
- A playground flag apiplaygroundultrafast has appeared
- Requests carry an OpenAI-Service-Tier: ultrafast header
- Docs still reference gpt-5.6-sol
Commenters note the best part, if it ships this way, is that all three subscription tiers reportedly get the new features instead of them being locked behind a new $500 tier.
