# MiniCPM-OCR 1.0 runtime for Hugging Face Jobs: cr.hf.co/davanstrien/minicpm-ocr
#
# - vLLM nightly 5d35ce3 (27 Oct 2026). MiniCPMOcrForConditionalGeneration landed in vLLM main on
#   23 Oct (18343393b4, the commit OpenBMB's install.sh builds from source) and is not in a
#   release yet; this nightly is newer and also has DSpark speculative decoding.
# - transformers at OpenBMB's pin (549e5b4, "5.21.0.dev0"). pip reports it as outside the nightly's
#   transformers>=5.16.1,<5.21.0 (a pre-release of 5.21.0 is excluded by <5.21.0); vLLM serves the
#   model with it (smoke test, 27 Oct 2026).
# - The minicpm-ocr SDK (layout, crops, assembly) in its own venv at /opt/sdk, as OpenBMB's docs
#   require (SDK and inference service in separate environments), with PaddlePaddle GPU for the
#   PP-DocLayoutV3 layout model.
# - The layout model is baked in (sha256-checked) at $OCR_ASSETS_DIR, so a run never fetches it
#   from Paddle's CDN. Model weights are not baked in: pull a pinned revision at run time.
