+# Tibetan OCR — Berkeley
+
+<!-- DRAFT. Kurt Keutzer (UC Berkeley) contributed transcriptions. Numbers measured 2026-08-18. -->
+
+**8,866 page images of Tibetan text with page-level Unicode transcriptions**, mostly
+dbu-med (u-med) manuscripts with a small woodblock (uchen) portion. The transcriptions
+were contributed by the group of **Prof. Kurt Keutzer (UC Berkeley)** and aligned to
+BDRC scans. Content skews toward Bön and Nyingma material (e.g. the Zhangzhung Nyengyü
+and Dzogchen cycles).
+
+Part of the **BDRC Tibetan OCR** release; see the model
+[`BDRC/tibetan-ocr`](https://huggingface.co/BDRC/tibetan-ocr) and the
+[evaluation benchmark](https://huggingface.co/datasets/BDRC/tibetan-ocr-benchmark).
