@ai-sdk/openai@4.0.78
@ai-sdk/openai v4.0.78 introduces support for reasoningEffortUpdate: 'none' for GPT-6 Sol and Luna, alongside validation for supported reasoning efforts.
Why this signal matters
In release @ai-sdk/openai@4.0.78 (commit 94d5d6d), support was added for setting reasoningEffortUpdate to 'none' for GPT-6 Sol and Luna models in both request-level options and positioned system messages. The update also includes validation logic that checks effort updates against the model's supported values: unsupported request-level updates trigger a warning and are omitted, while unsupported historical updates are rejected.
