Overview

con-cord/Mod2-no-ref is a 4.3 billion parameter medical LLM-as-a-Judge model, built upon the Gemma-3-4B base architecture. This particular version, no-ref, is uniquely designed to evaluate generated medical answers without the need for expert reference answers. It leverages frameworks like Transformers, PEFT/LoRA, and TRL for its fine-tuning process.

Key Capabilities

  • Medical Response Evaluation: Specialized in assessing the quality and accuracy of AI-generated medical text.
  • Reference-Free Assessment: Operates effectively by evaluating against predefined clinical criteria, eliminating the dependency on ground truth answers.
  • Gemma-3-4B Base: Benefits from the foundational capabilities of the Gemma-3-4B model.

Good For

  • Automated quality control of medical large language models.
  • Scenarios where expert reference answers are unavailable or difficult to obtain.
  • Evaluating adherence to clinical guidelines in AI-generated medical content.
