# Large language model performance matrix for Observability
This page summarizes internal test results comparing large language models (LLMs) across Observability [AI chat](https://www.elastic.co/docs/explore-analyze/ai-features/ai-chat-experiences) use cases. These ratings only apply if you're using [AI Assistant](https://www.elastic.co/docs/solutions/observability/ai/observability-ai-assistant). For Agent Builder, refer to [recommended models](/docs/explore-analyze/ai-features/agent-builder/models#recommended-models).
<warning applies-to="Elastic Cloud Serverless: Generally available, Elastic Stack: Generally available since 9.4">
  The Elastic AI Assistant for Observability and Search is deprecated. The [Elastic AI Agent](https://www.elastic.co/docs/explore-analyze/ai-features/elastic-agent-builder) is now the default chat experience in Observability. To switch back to the AI Assistant, go to **GenAI settings**.

**Rating legend**
For each category, the evaluation framework produces a score between 0–100 based on the criteria defined. This score is then converted to a rating using the following legend:

| Score    | Rating                                                                         |
|----------|--------------------------------------------------------------------------------|
| 84%–100% | **Excellent**: Highly accurate and reliable for the use case.                  |
| 75%–83%  | **Great**: Strong performance with minor limitations.                          |
| 45%–74%  | **Good**: Possibly adequate for many use cases but with noticeable tradeoffs.  |
| 0%–44%   | **Poor**: Significant issues; not recommended for production for the use case. |

Recommended models are those rated **Excellent** or **Great** for the particular use case.

## Evaluate your own model

You can run the Observability AI evaluation framework against any model, and use it to benchmark a custom or self-hosted model against the use cases in the matrix. Refer to the [evaluation framework README](https://github.com/elastic/kibana/blob/main/x-pack/solutions/observability/plugins/observability_ai_assistant_app/scripts/evaluation/README.md) for setup and usage details.
For consistency, all ratings in this matrix were generated using `Gemini 2.5 Pro` as the judge model (specified through the `--evaluateWith` flag). Use the same judge when evaluating your own model to ensure comparable results.
