# Examples

Real model output, verbatim from benchmark runs, the same task answered by the same model
with no skill (`## Without Ponytail`) and with ponytail (`## With Ponytail`), so you can
compare side by side. Model: Claude Haiku 4.5, temperature 1, source `benchmarks/output.json`.

These are not hand-written. Reproduce them yourself:
`npx promptfoo@latest eval -c benchmarks/promptfooconfig.yaml`. Method, all three models, and
median-of-10 numbers: [../benchmarks/](../benchmarks/).
