 Investbrain offers an AI powered chat assistant that is grounded on *your* investments. This enables you to use AI as a thought partner when making investment decisions. 
 
-When self-hosting, you can enable the chat assistant by configuring your OpenAI Secret Key and Organization ID in your [.env](https://github.com/investbrainapp/investbrain/blob/main/.env.example) file. Navigate to OpenAI to [create your keys](https://platform.openai.com/api-keys).
+Most of the major labs are currently supported (OpenAI, Anthropic, Gemini, xAI, etc). You'll need to obtain API keys from your selected provider and configure that in your [.env](https://github.com/investbrainapp/investbrain/blob/main/.env.example) file using the appropriate keys. 
 
-If you are self-hosting your own large language models ("LLMs") that expose an OpenAI compatible API (e.g. [Ollama](https://ollama.com/blog/openai-compatibility)), you can update the `OPENAI_BASE_URI` configuration to your self-hosted instance. Ensure you also update the `OPENAI_MODEL` to an available model.
