OpenRouter Auto Router Now Shows Which Model Handles Each Prompt

Key Info

OpenRouter's Auto Router (openrouter/auto) now records completion.model on every call, so you can see exactly which model was selected for each prompt. A retry can duplicate a billable call if the first request succeeded but the task failed before returning, so production code should use idempotency keys.

Highlights

• Auto Router returns completion.model per run, making model selection transparent.
• Works well with Render Workflows: each prompt becomes a queued, retried task run.
• Retries may repeat a billable call if the original request succeeded but the workflow failed before returning.
• Add idempotency for production side effects to avoid duplicate charges or actions.
