Once you've chosen a benchmark, run it with `lighteval eval`. Below are examples for common setups.

### Examples

1. Evaluate a model via Hugging Face Inference Providers.

```bash
lighteval eval "hf-inference-providers/openai/gpt-oss-20b" gpqa:diamond
```

2. Run multiple evals at the same time.

```bash
lighteval eval "hf-inference-providers/openai/gpt-oss-20b" gpqa:diamond,aime25
```

3. Compare providers for the same model.

```bash
lighteval eval \
    hf-inference-providers/openai/gpt-oss-20b:fireworks-ai \
    hf-inference-providers/openai/gpt-oss-20b:together \
    hf-inference-providers/openai/gpt-oss-20b:nebius \
    gpqa:diamond
```

You can also compare every providers serving one model in one line:

```bash
    hf-inference-providers/openai/gpt-oss-20b:all \
    "lighteval|gpqa:diamond|0"
```

4. Evaluate a vLLM or SGLang model.

```bash
lighteval eval vllm/HuggingFaceTB/SmolLM-135M-Instruct gpqa:diamond
```

5. See the impact of few-shot on your model.

```bash
lighteval eval hf-inference-providers/openai/gpt-oss-20b "gsm8k|0,gsm8k|5"
```

6. Optimize custom server connections.

```bash
lighteval eval hf-inference-providers/openai/gpt-oss-20b gsm8k \
    --max-connections 50 \
    --timeout 30 \
    --retry-on-error 1 \
    --max-retries 1 \
    --max-samples 10
```

7. Use multiple epochs for more reliable results.

```bash
lighteval eval hf-inference-providers/openai/gpt-oss-20b aime25 --epochs 16 --epochs-reducer "pass_at_4"
```

8. Push to the Hub to share results.

```bash
lighteval eval hf-inference-providers/openai/gpt-oss-20b hle \
    --bundle-dir gpt-oss-bundle \
    --repo-id OpenEvals/evals \
    --max-samples 100
```

9. Change model behaviour

You can use any argument defined in inspect-ai's API.

```bash
lighteval eval hf-inference-providers/openai/gpt-oss-20b aime25 --temperature 0.1
```

10. Use model-args to use any inference provider specific argument.

```bash
lighteval eval google/gemini-2.5-pro aime25 --model-args location=us-east5
```

```bash
lighteval eval openai/gpt-4o gpqa:diamond --model-args service_tier=flex,client_timeout=1200
```


LightEval prints a per-model results table:

```
Completed all tasks in 'lighteval-logs' successfully

|                 Model                 |gpqa|gpqa:diamond|

run "inspect view --log-dir lighteval-logs" to view the results
