The website only reads a baked catalog and the committed data/models.json snapshot. Pages do not call upstream APIs. This page records the licensed sources used to build that snapshot. Some figures were name-matched and reordered; we have not invented prices, official names, or scores.
Model metadata and provider prices. License: MIT. Material: models.dev.
Official public pricing API at tryallapi.com/api/pricing, converted with the official pricing-page formula. This is a third-party gateway, not an official model-vendor endpoint.
Benchmark scores and model metadata from benchmark_data.zip. License: CC-BY 4.0. Creator: Epoch AI. Material: epoch.ai/benchmarks/use-this-data.
Modifications: we name-match models, drop files that reprint Artificial Analysis or (except WebDev Arena) LMArena sources, and point WebDev Arena attribution at Epoch because we consume Epoch’s CC-BY reprint rather than scraping LMArena.
Official leaderboard CSVs from the LiveBench GitHub Pages repository. License: Apache-2.0. The datasheet states there are no copyrights on the data. Site: livebench.ai.
Modifications: we average official task columns by category and use only the post-change Coding era (code_generation).
Parameter counts and licenses for public open-weight model cards, judged per model. We do not invent a license when a card is silent. Material: huggingface.co.
When the Hub card license is verified as CC-BY 4.0, we may read lmarena-ai/leaderboard-dataset. License: CC-BY 4.0. Creator: LMArena. This is the rights-holder’s published dataset, not a scrape of lmarena.ai or arena.ai (those sites are not fetched).
Modifications: we use the latest split, omit the webdev config (already covered by Epoch’s reprint), name-match models, and reorder scores.
