Changelog Entry

Description

Added a new setting to enable title generation by CoT models.
Added fallback logic for title generation by CoT models (when the setting is off).

Added

Title generation fallback behavior when using a CoT model
Interface setting "Title generation model uses chain of thought"

Changed

Refactored max_tokens/max_completion_tokens while adding the new behavior
Truncate titles to 50 characters immediately before title update
Refactored title fallback logic
Moved reasoning tags names to a constant

Deprecated

None

Removed

None

Fixed

Fixed titles being updated with CoT e.g. <think>...

Security

None

Breaking Changes

None

Additional Information

Currently, running chain-of-thought (CoT) models will generate unhelpful titles in the sidebar unless a different model is selected for title generation in the interface settings. For example:

This PR lets CoT models generate helpful titles by 1) adding a default behavior to fall back to the original assistant message if a CoT is detected and 2) through a new setting, letting a CoT model fully generate a message before extracting just the generated title.

New interface setting "Title generation model uses chain of thought"
