FAQPage Schema
How do I benchmark LLMs across multiple tasks like GSM8K and HumanEval?

To benchmark LLMs, you can use a unified evaluation harness to evaluate models across 60+ tasks like GSM8K and HumanEval with standardized prompts and metrics. Configure models and data flows via YAML and command-line options to achieve reproducible results.

Can I use vLLM to run LLM benchmarks instead of HuggingFace?

Yes, you can use vLLM to run LLM benchmarks. The evaluation harness supports multiple backends, including HuggingFace, vLLM, and API-based interfaces, enabling flexible deployment and scalable benchmarking for your models.

What is the best way to compare model quality and track training progress?

The best way to compare model quality and track training progress is using a unified framework that benchmarks LLMs with standardized metrics. This approach enables reproducible comparisons and progress tracking across experiments using a common prompt format.

How do I configure tasks and models for reproducible LLM evaluation?

You configure tasks and models for LLM evaluation via YAML files and command-line options. This configuration method defines data flows and model parameters to achieve reproducible, shareable benchmarking results across different experiments.

Does the lm-evaluation-harness framework support API-based models?

Yes, the lm-evaluation-harness framework supports API-based models. It evaluates LLMs across 60+ benchmarks using multiple backends, including API-based interfaces, allowing you to benchmark remote models alongside local ones.
