+## Evaluation models
+{% data variables.product.prodname_copilot %} offers access to evaluation models—including top-performing open source and open-weight models—to provide the most advanced coding suggestions available.
+
+> [!NOTE]
+> Testing of evaluation models has revealed that some may perform worse than other models on security-related or other categories of prompts. Customers are encouraged to validate code, including code security, using a range of models and thorough human review before incorporating suggestions into production.
+
+Evaluation models may be added, updated, or removed without notice. Availability and rate limits may differ from generally available models.
