BenchCAD Vision2Code โ generate CadQuery from multi-view part renders. This page ranks models that have published a BenchCAD score, with live API token prices on the same row.
This page is the BenchCAD leaderboard. Models are sorted by BenchCAD, with input and output token prices on the same row so you can weigh score against cost. Official boards often omit price; that comparison is the point of this index.
Official eval pages own the methodology. This page keeps the published BenchCAD score next to live API $/M so you can pick a production SKU, not only a trophy number.
