Benchmarks: 95 of 190 measured

The tick on a coding bar is the median of every model measured on it. Outside coding, the place is this model's rank on that board. A board that never ran the model says so.

What it costs

A list price says what a token costs. The cost per solved task says what a working answer costs, which is the number that decides.

Output price against the market

o4 Mini pricing
$0.0112Dashed line: median $1.80, log scale$600.00
$4.40 per million output tokens is cheaper than 27% of the 344 paid models in the catalog.

Cost per solved task

How it is computed

SWE-bench Verified lists a pass rate for this model but no cost per attempt, on Vals AI and on swebench.com alike. We leave the number out rather than estimate it.

Nearly as good as o4 Mini, for less

What the boards say about its runs

Beside a result, many boards publish what the run cost, how long it took, the tokens it spent or the votes behind a rating. Each figure as its board printed it, one board per row.
