# March

## Gemini 2.5 Pro Experimental model

*March 27th, 2025*

We've added Google's Gemini 2.5 Pro Experimental model to Humanloop!

Gemini 2.5 Pro Experimental ranks #1 on [LMArena](https://lmarena.ai/?leaderboard) and features enhanced reasoning capabilities with a 1 million token context window.
It excels in complex tasks like mathematics, science, and coding by reasoning through its thoughts before responding.

## Improved Log search

*March 7th, 2025*

We've improved search on Logs to make it easier to find specific Logs based on their content.
You can select the search target in a dropdown beside the search box to search by inputs, output, messages, or metadata.

Select "All" in the search target dropdown beside the search box to search across all fields (emulating the previous behavior of our search bar).

## Log from Vercel AI SDK via OpenTelemetry

*March 7th, 2025*

![](/docs/_fern-files/humanloop.com/26305118b02f92fbaf810a72b38c714ccfa6df1b21135de50bce4bb0960ff378/humanloop.docs.buildwithfern.com/docs/2025-08-13T04:13:40.157Z/assets/images/changelogs/vercel-logotype-light.png)

We've added support for importing OpenTelemetry traces from the Vercel AI SDK. This allows you to see the steps taken by any AI system in Humanloop.

To try it, you need to enable the `experimental_telemetry` flag for each Vercel AI SDK call and configure the OpenTelemetry SDK to instrument your code.

Follow our [guide to the Vercel AI SDK](/docs/v5/integrations/vercel-ai-sdk) to learn more.

## New filters in Logs tab

*March 6th, 2025*

We've made filtering in Logs tab more intuitive and powerful with a revamped UI.

You can now filter logs by *metadata key-value pairs*, *evaluator judgments*, and more, making it easier to find exactly what you need.

![Screenshot showing the new filters in the Logs tab](/docs/_fern-img/d032ea06509ebe6ac0e7c375df5cabd01153494e800f2cd61b40276f7e8126ee.webp)

To check it out, navigate to the Logs tab and click on the **Filter** button to quickly find the logs you need.
