DeepSWE — software engineering agent benchmark on real repositories. This page ranks models that have published a DeepSWE score, with live API token prices on the same row.
This page is the DeepSWE leaderboard. Models are sorted by DeepSWE, 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 DeepSWE score next to live API $/M so you can pick a production SKU, not only a trophy number.
