# Chartography (no tools) — AI model rankings

The same chart-centred test with no tools: the AI has to read each chart unaided. Scores run far lower than the with-tools version, so read the two as separate tests. Higher is better.

3 tracked models have a published Chartography (no tools) score. Higher is better. Scores come from published lab reports and benchmark sources; recorded sources appear beside the scores.
