Limits
| Limit | Value | Notes |
|---|---|---|
| Maximum request body | 32 MB | Hosting platform limit. Base64 adds about 33% to file size. |
| Recommended image file size | ≤ 4 MB | Faster uploads and responses; accuracy isn't improved by very large images |
| Request timeout | 300 seconds | Requests taking longer are terminated by the platform (504) |
| Client timeout (recommended) | 60 seconds |
Latency. Requests to a warm service typically complete in about a second or less. The first request after a new server instance starts can take noticeably longer while models load. Instances process predictions one at a time, so bursts of traffic may queue, and very large bursts can see 429/503 from the platform. Use the retry policy in Errors & retries.
Data handling. Images are stored for processing. Sylvester does not use your images or predictions for any purpose other than fulfilling your request or model improvements. See the Privacy policy for details.
