# CharXiv Reasoning (with tools) — AI model rankings

The same chart-and-figure reasoning test, run with the AI allowed to use tools — writing code to inspect the image, for instance — rather than reading the chart unaided. Scores run higher than the unaided version, so read the two as separate tests. Higher is better.

1 tracked model have a published CharXiv Reasoning (with tools) score. Higher is better. Scores are as published at each model's release.
