📄 Description

Changelog Entry

Description

Implemented feature request #20668 by ankush13r. Added toggleable, turn persistent models per Arena chat. At the beginning of an Arena chat, one model is chosen for the duration of that chat. This can be disabled in Admin Panel -> Settings -> Evaluations. This allows models to be evaluated in Arena across multiple turns.

Added

  • Arena model cached for Arena chats.
  • Toggle per chat/per turn Arena model in Admin Panel -> Settings -> Evaluations.

Changed

  • Arena chat has a persistent model for chat by default, instead of models changing per turn.

Additional Information

  • This PR is not written by any AI agent.

  • Code Review has been performed, and functionality has been recorded:

  • The functionality of this feature was tested by recording five prompts with per-chat caching enabled and disabled. As both of these tests passed, I can verify this feature as working

Before (Or with per-chat caching disabled):
