Rate limits

Optional rate limits on Self-Managed instances for stability

You can configure rate limits on your W&B Self-Managed instance to maintain stability and prevent one user or workload from negatively impacting others. These limits are optional. If you do not set them, the instance does not enforce the limits described below.

Default limits and notification

The following default limits help maintain platform stability:

Limit	Default	Scope
Filestream requests per second	500	Project
Filestream size	120 MB per second	Project
Filestream requests per run per second	2	Run
Run creation requests per second	80	Project

When a limit is exceeded, the W&B SDK returns HTTP 429. You may see a message such as the following in your SDK logs:

HTTP 429: rate limit exceeded

These defaults are recommended for typical production workloads. If your workloads consistently exceed these limits, you can configure these limits (or leave them unset) according to your instance size and shared usage. For configuration details, refer to Deploy W&B with Kubernetes Operator or contact W&B support.
