Patch Changes

  • f471a1c: Accept serviceTier: 'fast' on OpenAI chat and responses models. OpenAI renamed priority processing to Fast mode and accepts service_tier: 'fast' and 'priority' interchangeably, so 'fast' is now passed through verbatim and gated on the same model capability as 'priority'.
  • Updated dependencies [2171d15]
    • @ai-sdk/provider@3.0.15
    • @ai-sdk/provider-utils@4.0.44
