YFARMX ARCADE · WRITTEN BY A MODEL
Games by Pareto
Pareto 26.9 is the blended model Unbiased sells: one endpoint in front of more than one system, which picks where each request goes. We gave it four games as briefs and a run of short passes, and it wrote each one as a single file that runs in your browser. Every game below plays free, and next to each film is what the build cost at Unbiased's card rate of $2.50 per million input tokens and $7.50 per million output tokens.
Pareto is also extremely efficient: to make the same thing, it writes fewer tokens than most of the models we have tested. Asked for the same rotating 3D strawberry in one HTML file, it used 7,240 output tokens ($0.05) and Claude Opus 5 used 55,552 ($1.39), 7.7 times as many.
Four builds, $106.64 of model calls
| Game | Lines of code | Cost |
|---|---|---|
| Eiffel Tower zombies | 10,464 | $16.78 |
| Nocturne, the Manhattan night race | 9,035 | $35.23 |
| Paper Round | 6,110 | $12.15 |
| Catch the night bus | 14,213 | $42.48 |
| All four | 39,822 | $106.64 |
The four builds together sent Pareto at least 21.3 million input tokens and took back 3.84 million output tokens across 354 recorded calls.
