​
HTTP status

400 invalid_request_error

​
Typical cause

The request sets tool_choice: "required" but the selected model doesn’t reliably guarantee a tool call in the response. Auriko rejects this combination to prevent silent failures in agentic pipelines.

​
Resolution

Use tool_choice: "auto" instead. Models still call tools when prompted appropriately. Alternatively, remove any provider constraint to allow routing to a capable provider.
