 ### Added
 - `UiPathChat` (normalized) now implements `_identifying_params` (returning `model_name` + `_default_params`) to match the `BaseChatOpenAI` convention, giving traced/cached runs a proper identity key instead of the empty default from `BaseChatModel`.
 
+### Changed
+- `UiPathChat._llm_type` now returns `"uipath-chat"` (was `"UiPath-Normalized"`) to align with the lowercase-hyphenated convention used by `openai-chat`, `azure-openai-chat`, etc.

 ### Changed
 - Bumped dependency floors to the latest installed versions: `langchain-openai>=1.1.16`.
