LLM Evaluation Metrics on Hugging Face 2026

If you pick open-source models, Hugging Face leaderboards are your first stop. The transformers library (163,208 stars) and the Open LLM Leaderboard ecosystem define how models get compared in 2026.

The key metrics

• MMLU: multi-task language understanding, 57 subjects. The standard general-knowledge test.
• HumanEval / MBPP: code generation pass@1. DeepSeek-Coder and Qwen3-Coder lead here.
• GSM8K / MATH: arithmetic and math reasoning.
• BBH (Big-Bench Hard): challenging reasoning tasks.
• MT-Bench / Arena Elo: chat quality judged by humans or strong models.
• RAGAS (11k+ stars): retrieval-augmented generation specific metrics - faithfulness, answer relevancy, context precision.

How to read a leaderboard responsibly

1. Check which exact model checkpoint was evaluated (base vs instruct vs chat versions differ a lot)
2. Look at the evaluation library version - scores are not comparable across versions
3. Prefer models evaluated with the same harness (lm-evaluation-harness, 5k+ stars)
4. Sample size matters: 5-shot vs 0-shot changes scores by several points

Real examples (mid-2026 open models)

• DeepSeek-V3 (104,067 stars) scores in the top tier of MMLU among open models
• Qwen2.5 series (27,455 stars) dominates multilingual and code benchmarks in its size class
• Small models: Qwen2.5-Coder 7B beats many 13B models on HumanEval

FAQ

Can I trust leaderboard scores? Yes, as a ranking signal - but re-run your own evals on your data before choosing. Where do I find community evals? Hugging Face model cards include evaluation results from the community.
