OLMES

Allen Institute for AI

Ai2's evaluation system behind the OLMo and Tülu releases, built on lm-evaluation-harness with deeper task configuration, instance-level prediction logging and external results storage for faithful reproduction of published numbers. It packages the OLMES standard for evaluating base and instruction-tuned models.

No PyPI package (olmes and oe-eval both 404); install is from source. Last push 2026-03-24, quiet for about five months but not archived, well inside the maintenance window; worth re-checking at the next refresh. Verified 2026-09-01 via the allenai/olmes repository, its license endpoint and its README.

Apache-2.0 and fully public: the LICENSE body is the stock Apache-2.0 text with no appended terms, and the README documents source-only install (`pip install -e .`) and local evaluation of HF models, with no pricing, paid tier, enterprise edition or license key anywhere in it.

Adoption

1 medium confidence
1.0

394 GitHub stars, which bands at level 1 on the stars scale (<1K). No download channel exists — no PyPI package (olmes and oe-eval both 404 this session), install is from source — and external usage beyond Ai2's own model releases is limited, so stars are the honest instrument. The provenance (the eval standard behind OLMo and Tülu) is capability and openness signal, not adoption.

Capability

3 medium confidence
3.0

Reproducibility-hardened derivative of lm-evaluation-harness with unusually deep task configuration and instance-level logging, but a far narrower task and backend surface than the broad platforms — dozens of curated suites against lighteval's 1000+ tasks and wider backend spread — so one below lighteval, beside bigcodebench.
