-- An account with a third-party generative AI provider that preferably supports function calling. If your AI provider does not support function calling, you can configure [AI Assistant settings](../../solutions/observability/observability-ai-assistant.md#obs-ai-settings) to simulate function calling, but this might affect performance.

-  - The free tier offered by third-party generative AI provider may not be sufficient for the proper functioning of the AI assistant. In most cases, a paid subscription to one of the supported providers is required.

-    Refer to the [documentation](kibana://reference/connectors-kibana/gen-ai-connectors.md) for your provider to learn about supported and default models.

-  - In {{ecloud}} or {{ece}}, if you have Machine Learning autoscaling enabled, Machine Learning nodes will be started when using the knowledge base and AI Assistant. Therefore using these features will incur additional costs.
