Current Status: Major Outage
Last checked: 17m ago
What We're Seeing Right Now
No recent issues reported. If you're experiencing problems with Modal, report below to help the community.
What is this error?
When Modal inference times out, the model took too long to load, initialize, or generate a response. Large models can have cold start times of 30-120 seconds, and inference itself can timeout under load.

- Cold start — model loading into GPU memory
- Model is too large for allocated resources
- Input is too large or complex
- Infrastructure overloaded
- Modal inference endpoint is degraded
✓ How to Fix It
- Increase timeout values in your client
- Use a smaller model variant if available
- Keep the endpoint warm with periodic requests
- Check if auto-scaling is configured
- Reduce input size
- Check this page for infrastructure issues

Frequently Asked Questions
Why is Modal inference timing out?
Large models have cold starts (30-120s). If timeouts persist, the model may need more resources or Modal may be overloaded.
How do I reduce Modal cold start time?
Keep endpoints warm, use smaller models, or use Modal's dedicated/reserved infrastructure.
