Deep Dive into G-Eval: How LLMs Evaluate Themselves

• eeasss 11mo ago
  Are there any llms in particular that work best with g-evals?

    LLM Benchmark leaderboard for common evals sounds like a fun idea to me.
  • zlatkov 11mo ago
    I haven’t come across any research showing that a specific LLM consistently outperforms others for this. It generally works best with strong reasoning models that produce consistent outputs.

  Interesting overview, though I still wonder how stable G-Eval really is across different model families. Auto-CoT helps with consistency, but I’ve seen drift even between API versions of the same model.
  • zlatkov 11mo ago
    That's true. Even small API or model version updates can shift evaluation behavior. G-Eval helps reduce that variance, but it doesn’t eliminate it completely. I think long-term stability will probably require some combination of fixed reference models and calibration datasets.

  We’ve tried geval but it hasn’t been super useful in practice. If we run the same input on the same model and same geval 10 times we get significantly different results, so you can’t really arrive at any conclusions based on the results.
