## Known failure modes

- Input text too long: may exceed model token limits, resulting in truncation or error
- Invalid max_length value: non-integer or negative value may cause a bad request error
- Empty or missing text field: returns an error or empty summary
- Network/inference timeout: Cloudflare Workers AI may timeout on very large inputs
