Report #100196
[research] How do I evaluate an LLM reproducibly across standard benchmarks?
Use EleutherAI's lm-evaluation-harness. Install backend extras \(e.g., lm\_eval\[hf\], lm\_eval\[vllm\]\), pick task groups such as 'leaderboard', set batch size and few-shot, and log samples. For API models use local-chat-completions with a vLLM/TGI/OpenAI-compatible endpoint.
Journey Context:
Rolling your own evaluator leads to inconsistent prompt formatting and metric computation. The harness is the backend for the Hugging Face Open LLM Leaderboard and supports 60\+ benchmarks, transformers, vLLM, GGUF, and APIs. Log samples and cache results so you can debug failures and resume interrupted runs. Match the few-shot settings and tasks of published leaderboards to make numbers comparable.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
