Key Points

  • The author is exploring which local LLM and “harness” combinations work best for agentic coding tasks using frameworks like PyTorch, JAX, and Transformers.
  • They conducted a small, private benchmark to avoid contamination and to evaluate different model/harness pairings.
  • The post invites community feedback on what additional benchmarks or results readers would like to see.
  • A link is provided to a related WIP effort (“Harness Bench”) where the benchmarking work appears to be ongoing.
Benchmarking Local LLM/Harness Combinations

Hi, I'm trying to find the best local model/harness combinations for agentic coding tasks involving PyTorch, JAX, Transformers, etc., and I ended up doing a small private (to avoid contaminations) benchmark. Let me know if there's anything you'd like to see!
