Recommended action: Upgrade @ai-sdk/togetherai (>=3.0.53); in raw clients omit seed/steps for non-diffusion models. Fix: Omit diffusion-only params [evidence: released_fix] Steps: 1. Upgrade @ai-sdk/togetherai 2. Do not send seed/steps for Gemini image models Expected: Request accepted Evidence basis (self-declared by the contributing chat client): untested.
