📄 Description

Description

Introduces an optional Greeting Message field for custom models. This allows model creators to define a predefined opening message (e.g., "How can I help you with your legal documents today?") that appears automatically when a user starts a new chat with that specific model.

This improves "cold-start" UX by providing immediate context or instructions without requiring initial user input.

Added

  • Backend: Added an optional greeting field to the ModelMeta schema to store the message in the model's metadata.
  • Frontend: Added a "Greeting Message" textarea in the Workspace → Models editor, positioned under the System Prompt field.
  • Chat Logic: Implemented auto-injection of the greeting message when a new, empty chat is initialized with a configured model.

Changed

  • Message Handling: Updated chat initialization logic to correctly identify "new chats" even when a greeting message is present (refactored messages.length === 0 checks).
  • Parent ID Logic: Adjusted the message threading to ensure the first user message correctly initializes the chat on the backend by sending a null parent ID, even if a greeting is visually present in the frontend history.

Fixed

  • Fixed an issue where switching models in an empty chat would leave stale greeting messages from the previous model selection.

Changelog Entry

Added

  • Optional "Greeting Message" support for custom models in Workspace settings.

Changed

  • Refactored new-chat detection logic to support pre-populated assistant greetings.

Fixed

  • Corrected parent_id initialization for the first user message when starting a chat via a model greeting.

Additional Information

  • This change ensures that if a field is left empty, the behavior remains identical to the current "user-starts-first" flow.
  • Verified that switching between models with and without greetings updates the UI state correctly without polluting the chat history until the first user message is sent.

Screenshots or Videos

(Note: Be sure to attach a screenshot of the new field in the Model Editor and the greeting appearing in the Chat UI here!)
