Changelog Entry
Description
This PR introduces new environment variables that allow separate model selection for task handling vs. tool-calling. Previously, the task model was also responsible for tool-calling, but with this change you can now:
Use a lightweight/cheap model for simple tasks (e.g., title or tag generation).
Configure a more capable model specifically for tool selection and invocation.
This separation gives more flexibility in balancing cost and performance.
Added
Created new environment variables TOOL_CALLING_MODEL and TOOL_CALLING_MODEL_EXTERNAL
Added UI elements in Admin Interface panel to select tool calling models
Changed
In the chat_completion_tools_handler, task_model_id checks for a TOOL_CALLING_MODEL/TOOL_CALLING_MODEL_EXTERNAL. If undefined, uses TASK_MODEL/TASK_MODEL_EXTERNAL
Deprecated
None
Removed
None
Fixed
Saves tokens on task queries while optimizing tool-calling performance
