Chat
The Chat page provides a browser-based chat interface for interactively talking to any model or Actor endpoint available in your workspace. It is the fastest way to test a new deployment, evaluate model quality, or debug Actor behavior without writing any code.
The Chat page is not a production interface — it uses your workspace session authentication rather than an API key, and requests are attributed to your user account. It is intended for exploration and testing. For production use, call the API directly or integrate via an SDK.
Sending messages
Type your message in the text input at the bottom of the chat panel and press Enter or click the send button. Responses stream in real-time. You can continue the conversation — the full message history is sent with each request, up to the model's context window limit.
Switching models
The model selector appears above the chat input. It lists all models and Actor endpoints deployed in any namespace you have access to. Switching models starts a new conversation — previous messages are cleared when you change the model.
