Fully Apache-2.0. The README header carries a 'Data License CC By NC 4.0' badge, but both badges link to the sibling tatsu-lab/alpaca_farm repository rather than to anything in this one, so the NC term is not a license this product makes you accept.

  README installs the evaluator with `pip install alpaca-eval` or straight from the git repo and runs it against the reader's own model outputs, printing a leaderboard locally; the annotator configs and reference outputs ship in the package. The only external cost named is the reader's own OpenAI credits, roughly $10 a run. No paid tier, hosted edition or license key appears in it.
