Known issues

  1. Colab notebooks aren’t supported by our Python auto-tracer

Tracing Rate Limits

We support up to 5MB on individual requests.

Our filters and aggregates are supported up to 5 levels of nesting.

We have a default rate limit of 1000 requests per minute.

Enterprise-plan users can set higher rate limits.

Our online evaluators can be scoped by event_type and event_name.

We can support more granular filters for evaluators if needed.

Latest Package Versions tested

As of 09/18/2024

The below tables list the latest version of a provider’s package that we have tested our tracers against. It’s often the case that future versions after these are also supported. As long as the providers haven’t changed the contract on the specific inference functions that are being auto-traced, the tracer will continue to work.
