Azure gpt-4o-mini deployments accept at most 16384 completion tokens and 400 on anything larger: max_tokens is too large: 32000. This model supports at most 16384 completion tokens, whereas you provided 32000. The 32000 is OmniRoute's own doing: adjustMaxTokens raises any smaller max_tokens to DEFAULT_MIN_TOKENS (32000) whenever tools are present, to avoid truncated tool arguments. That floor has no upper bound, so an agentic client asking for far less still trips the model ceiling on its first turn. Add scoped maxOutputCap rules in paramSupport.ts for both Azure wire paths. PROVIDER_MAX_TOKENS is the wrong lever here - it is provider-wide, and the same Azure resource also serves GPT-5 deployments with a much higher ceiling. Regression guard: tests/unit/azure-max-output-clamp.test.ts, which also pins that the clamp does not leak to gpt-5.1 or to gpt-4o-mini on other providers.
