Bumps marker-pdf from 1.10.2 to 2.0.0.

Release notes

Sourced from marker-pdf's releases.

Marker 2.0.0

Marker 2 is a rewrite focused on speed, full CPU support, and accuracy. It's built on three new pieces we shipped over the last few months: Surya OCR 2, a 20M-param fast layout model, and a rebuilt (3× faster) pdftext.

Against comparable pipeline OCR systems, Marker 2 is both faster and more accurate — on olmOCR-bench, balanced mode scores 76.0% overall (83.5% on born-digital) while running over 5× more pages/sec than MinerU's pipeline backend.

Highlights

• Conversion modes. Choose your speed/accuracy tradeoff:
  • balanced — surya VLM for layout + full-page OCR when text is bad. Highest quality; best on GPU. 76.0% olmOCR-bench.
  • fast — lightweight rf-detr/onnx layout + pdftext, with minimal, surgical VLM use. 66.6%, and far cheaper.
  • --disable_ocr — pure text-layer extraction, no VLM at all. Runs entirely on CPU. 43.6%, 23.7 pg/s.
• Device-aware default. Mode now defaults by device automatically — balanced on GPU, fast on CPU/MPS — so you get a sensible speed/accuracy tradeoff without a flag. Override any time with --mode.
• Full CPU support. fast --disable_ocr needs no GPU and no inference server; the 20M layout model runs on CPU and still reads structure (columns, tables, headers).
• Throughput by design. Many thin CPU workers share a single surya inference server; the parent process budgets VLM concurrency across them, so throughput scales with server capacity instead of per-process VRAM. Sustained on one B200: 2.9 pg/s balanced, 7.4 pg/s fast, 23.7 pg/s no-OCR.
• Selective OCR. Marker reads the PDF text layer with pdftext and only calls the VLM where it's needed — garbled/scanned pages, equations, low-confidence tables — instead of VLM-OCRing every page.
• Reproducible benchmarks. A new benchmarks/ harness reproduces every olmOCR-bench score and throughput number in the README, for marker and competitors (MinerU, docling, liteparse).

Breaking changes

• Python 3.10+ required.
• Packaging moved from Poetry to uv (build backend is now hatchling). pip install marker-pdf is unchanged.
• The unused structured-extraction converter/extractors were removed; use the Datalab API or a --use_llm workflow for structured extraction.
• Mode default is now device-dependent rather than always balanced (see above).

Install

pip install marker-pdf          # PDFs
pip install marker-pdf[full]    # + docx, pptx, xlsx, epub, html

Benchmarks (olmOCR-bench, macro-average over 8 categories)

Mode	Overall	Digital-only	Throughput (B200)
balanced (GPU)	76.0	83.5	2.9 pg/s
fast (GPU)	66.6	71.6	7.4 pg/s
fast, no OCR (CPU)	43.6	55.8	23.7 pg/s

Full per-category scores, the competitive comparison, and reproduction steps are in the README.

For the highest possible accuracy, the hosted Datalab API runs Chandra (our document VLM) with automatic correction - free $5 in credits to try.
