How researchers are adapting olmOCR 2 for historical and archaeological archives

Researchers are adapting Ai2's open olmOCR 2 model to transcribe historical and archaeological archives. Historian Maurice Casey built ArtificeOCR, which runs olmOCR 2 locally with Tropy to make his archival photo library keyword-searchable, while TU Wien's CENTURIA project fine-tuned olmOCR 2 with LoRA on 57 annotated records, cutting transcription error on 450 test records from 15.58% to 1.11%.
