  1. 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 or the API, then create a knowledge base, and lastly updating your 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.
