Trace every step of your requests 🕵️‍♂️📡

Trace every step of your requests 🕵️‍♂️📡

We’re thrilled to share with you the latest update to Openlayer: comprehensive tracing capabilities and enhanced request streaming with function calling support.

Now, you can trace every step of a request to gain detailed insights in Openlayer. This granular view helps you to debug and optimize performance.

Additionally, we’ve expanded our request streaming capabilities to include support for function calling. This means that requests you stream to Openlayer are no longer a black box, giving you improved control and flexibility.
