FAQPage Schema
How do I benchmark LLMs across multiple academic tasks?

Benchmarking LLMs involves running 60+ academic tasks like MMLU and HumanEval through the lm-eval framework to collect standardized metrics for model comparison. This harness uses backends like transformers or vllm to load and execute models.

Can I use vllm to run LLM evaluations?

Yes, LLM evaluations support vllm as a backend to load and execute models. The harness works with HuggingFace and API-based interfaces alongside vllm, providing backend flexibility for diverse deployment scenarios during benchmarking.

What is the best way to track LLM training progress with standardized metrics?

The best way to track LLM training progress is benchmarking models across 60+ academic tasks to collect standardized metrics. This approach applies to progress tracking and reporting in research or production benchmarks for reproducible results.

Does the LLM evaluation harness support GSM8K and TruthfulQA?

Yes, the LLM evaluation harness supports GSM8K and TruthfulQA alongside MMLU, HumanEval, HellaSwag, and ARC. It provides wide task coverage with standardized prompts and metrics for rigorous language model benchmarking.

Do I need lm-eval to benchmark HuggingFace models?

Yes, you need the lm-eval framework to benchmark HuggingFace models. The harness requires lm-eval to execute 60+ academic tasks and relies on common backends like transformers and vllm to load models for evaluation.
