Hugging Face Community Evals

If the user wants to publish results into the community evals workflow, stop after generating the evaluation run and hand off that publishing step to ~/code/community-evals.

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
• hand off to the hugging-face-jobs skill 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, hand off to hugging-face-jobs with the same script + args.

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 switch to the hugging-face-jobs skill and pass it one of these scripts plus the chosen arguments.

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, hand off to hugging-face-jobs
• 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

Examples

See:

• examples/USAGE_EXAMPLES.md for local command patterns
• scripts/inspect_eval_uv.py
• scripts/inspect_vllm_uv.py
• scripts/lighteval_vllm_uv.py

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
