+2. **Configure Custom Knowledge Bases for your Assistant**: Configure a custom knowledge base for your assistant in three steps by first uploading a file [through the dashboard](https://dashboard.vapi.ai/files) or  [the API](https://api.vapi.ai/api#/Files/FileController_create), then [create a knowledge base](https://docs.vapi.ai/knowledgebase#step-2-create-a-knowledge-base), and lastly [updating your assistant](https://docs.vapi.ai/knowledgebase#step-3-create-an-assistant) with the knowledge base id. You can also assign a knowledge base to models like `GroqModel`, `VapiModel`, `GoogleModel`, and others using the new `knowledgeBaseId` property.
