Coding Agent 524 Timeout: Base URL, Streaming, and max_tokens Fix
Use streaming when supported, bound output with max_tokens or max_output_tokens, split large repository tasks, and inspect Usage Logs before retrying.

Configuration summary
Steps
- Confirm the request uses https://api.metisrouter.com/v1 or the documented direct provider endpoint.
- Copy the exact model ID from /models or /docs/models.
- Set a bounded max_tokens, max_completion_tokens, or max_output_tokens value when the task can grow.
- Send a short test request and check Usage Logs for the request id, latency, usage, and charged amount.
Symptoms
Long coding-agent requests time out during repository analysis, tool loops, or large patch generation.
- The tool may show an authentication, model, streaming, timeout, or provider error.
- Usage Logs help separate requests blocked by MetisRouter from requests that reached an upstream provider.
Why it happens
Most setup failures come from mismatched base URLs, display names used as model IDs, missing output limits, unsupported endpoint types, or insufficient balance.
- Use API model IDs, not prettified display names.
- Match text, image, video, audio, and embedding requests to their documented endpoints.
- Keep request IDs for support and retries.
How to verify
After applying the fix, run one short request and confirm the platform recorded the model, endpoint, token or asset usage, latency, and cost.

FAQ
Should I retry immediately?
Retry only after checking whether Usage Logs already show a successful upstream request or a billable result.
Which model ID should I use?
Use the exact API model ID from /models or /docs/models. Display titles are not guaranteed to work as request model IDs.
