Huggingface Community Evals

Overview

This skill is for running evaluations against models on the Hugging Face Hub on local hardware.

It covers:

• inspect-ai with local inference
• lighteval with local inference
• choosing between vllm, Hugging Face Transformers, and accelerate
• smoke tests, task selection, and backend fallback strategy

It does not cover:

• Hugging Face Jobs orchestration
• model-card or model-index edits
• README table extraction
• Artificial Analysis imports
• .eval_results generation or publishing
• PR creation or community-evals automation

If the user wants to run the same eval remotely on Hugging Face Jobs, submit the same script via hf jobs uv run (CLI) or the hf_jobs() MCP tool if configured, for remote GPU execution.

If the user wants to publish results into the community evals workflow, stop after generating the evaluation run and hand that publishing step off to the project's own community-evals workflow.

All paths below are relative to the directory containing this SKILL.md.

When To Use Which Script

Prerequisites

• Prefer uv run for local execution.
• Set HF_TOKEN for gated/private models.
• For local GPU runs, verify GPU access before starting:

uv --version
printenv HF_TOKEN >/dev/null
nvidia-smi

If nvidia-smi is unavailable, either:

• use scripts/inspect_eval_uv.py for lighter provider-backed evaluation, or
• submit it to Hugging Face Jobs (hf jobs uv run or hf_jobs()) if the user wants remote compute.

Core Workflow

1. Choose the evaluation framework.
   • Use inspect-ai when you want explicit task control and inspect-native flows.
   • Use lighteval when the benchmark is naturally expressed as a lighteval task string, especially leaderboard-style tasks.
2. Choose the inference backend.
   • Prefer vllm for throughput on supported architectures.
   • Use Hugging Face Transformers (--backend hf) or accelerate as compatibility fallbacks.
3. Start with a smoke test.
   • inspect-ai: add --limit 10 or similar.
   • lighteval: add --max-samples 10.
4. Scale up only after the smoke test passes.
5. If the user wants remote execution, submit the same script + args to Hugging Face Jobs (hf jobs uv run or hf_jobs()).

Quick Start

Option A: inspect-ai with local inference providers path

Best when the model is already supported by Hugging Face Inference Providers and you want the lowest local setup overhead.

uv run scripts/inspect_eval_uv.py \
  --model meta-llama/Llama-3.2-1B \
  --task mmlu \
  --limit 20

Use this path when:

• you want a quick local smoke test
• you do not need direct GPU control
• the task already exists in inspect-evals

Option B: inspect-ai on Local GPU

Best when you need to load the Hub model directly, use vllm, or fall back to Transformers for unsupported architectures.

Local GPU:

uv run scripts/inspect_vllm_uv.py \
  --model meta-llama/Llama-3.2-1B \
  --task gsm8k \
  --limit 20

Transformers fallback:

uv run scripts/inspect_vllm_uv.py \
  --model microsoft/phi-2 \
  --task mmlu \
  --backend hf \
  --trust-remote-code \
  --limit 20

Option C: lighteval on Local GPU

Best when the task is naturally expressed as a lighteval task string, especially Open LLM Leaderboard style benchmarks.

Local GPU:

uv run scripts/lighteval_vllm_uv.py \
  --model meta-llama/Llama-3.2-3B-Instruct \
  --tasks "leaderboard|mmlu|5,leaderboard|gsm8k|5" \
  --max-samples 20 \
  --use-chat-template

accelerate fallback:

uv run scripts/lighteval_vllm_uv.py \
  --model microsoft/phi-2 \
  --tasks "leaderboard|mmlu|5" \
  --backend accelerate \
  --trust-remote-code \
  --max-samples 20

Remote Execution Boundary

This skill intentionally stops at local execution and backend selection.

If the user wants to:

• run these scripts on Hugging Face Jobs
• pick remote hardware
• pass secrets to remote jobs
• schedule recurring runs
• inspect / cancel / monitor jobs

then submit one of these scripts plus the chosen arguments to Hugging Face Jobs (hf jobs uv run or hf_jobs()).

Task Selection

inspect-ai examples:

• mmlu
• gsm8k
• hellaswag
• arc_challenge
• truthfulqa
• winogrande
• humaneval

lighteval task strings use suite|task|num_fewshot:

• leaderboard|mmlu|5
• leaderboard|gsm8k|5
• leaderboard|arc_challenge|25
• lighteval|hellaswag|0

Multiple lighteval tasks can be comma-separated in --tasks.

Backend Selection

• Prefer inspect_vllm_uv.py --backend vllm for fast GPU inference on supported architectures.
• Use inspect_vllm_uv.py --backend hf when vllm does not support the model.
• Prefer lighteval_vllm_uv.py --backend vllm for throughput on supported models.
• Use lighteval_vllm_uv.py --backend accelerate as the compatibility fallback.
• Use inspect_eval_uv.py when Inference Providers already cover the model and you do not need direct GPU control.

Hardware Guidance

For smoke tests, prefer cheaper local runs plus --limit or --max-samples.

Troubleshooting

• CUDA or vLLM OOM:
  • reduce --batch-size
  • reduce --gpu-memory-utilization
  • switch to a smaller model for the smoke test
  • if necessary, submit the run to Hugging Face Jobs instead
• Model unsupported by vllm:
  • switch to --backend hf for inspect-ai
  • switch to --backend accelerate for lighteval
• Gated/private repo access fails:
  • verify HF_TOKEN
• Custom model code required:
  • add --trust-remote-code
