Chemistry tests now show where AI reasoning breaks

What changedChemArgus scores every reasoning step and compares image-plus-text questions with controlled text descriptions to separate visual integration, propagation, and local reasoning failures. A low final answer score becomes a diagnosis of the broken step, which is more useful for scientific assistants than one pass-or-fail number.

The ChemArgus overview maps chemistry questions to step-level scoring and diagnostic reasoning gaps.

The useful part

Why it matters

A low final answer score becomes a diagnosis of the broken step, which is more useful for scientific assistants than one pass-or-fail number.

Keep in mind

Good to know

This is a benchmark study; it does not show that the evaluated models can safely perform laboratory work.
