Benchmarks: 99 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

GPT-5 Mini pricing
$0.0112Dashed line: median $1.80, log scale$600.00
$2.00 per million output tokens is cheaper than 44% of the 344 paid models in the catalog.

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.
