How models are selected
Generally-available models with a SWE-bench Verified score (resolving real GitHub issues) or a code-specialized release, ranked by independently-evaluated SWE-bench Verified. One row per model — host duplicates are collapsed. Vendor-reported scores are shown flagged and ranked below independently-scored models, never against them; models with no published score rank last, cheapest first. Prices shown are verified against official provider pages.
Prices are per million tokens (Mtok), sourced directly from — and linked to — official provider pricing pages. "Blended cost" is (3×input + 1×output) ÷ 4 — weighted toward input because real workloads read far more tokens than they generate.
