How AI models read oral and maxillofacial radiographs

I study how AI models read oral and maxillofacial radiographs, including independent evaluation of frontier vision-language models, and I build structured reporting methodology for oral and maxillofacial radiology.

The evaluation runs in public as Radigrade, a registered benchmark for grading AI-written radiograph reports. Each report is compared with a reference read by two oral and maxillofacial radiologists reading together, one axis at a time, with no blended score and no rank. The protocol is registered on OSF, and the results, the protocol text and the change log are at radigrade.com.

Now

What I’m building

How AI reports are graded in public, the automation in production, and the open-source instruments, kept honest with a date.

Instruments

Open-source tools built for this work

Agent-native instruments: each exposes a bounded set of verbs to an AI agent over MCP while the human keeps commit rights.
