Changelog

​

8/5/2025

• Launch a new OCR model with improved math performance.
• Improve marker quality in cases where there are inline equations or other text that needs OCR.

​

7/25/2025

• Improve speed of LLM mode and when outputting multiple output formats.

​

7/20/2025

• Launch a visual editor for structured extraction that lets you edit schemas and visualize results.

​

7/15/2025

• Add a visual editor for marker prompts that lets you see how the document was changed, test across documents, and save prompts.

​

7/1/2025

• Structured extraction beta - pass page_schema to the marker endpoint to extract structured data from documents. The schema should be a pydantic schema generated with .model_dump_json_schema(), or another JSON schema format.
• Support the new chunks output format for marker, which is a simplified list of blocks with their full html, ideal for chunking/RAG.
• Marker endpoint is now promptable - pass block_correction_prompt to the marker endpoint to correct the output of marker with your custom logic.
• We support additional configuration parameters for marker via the additional_config parameter. This is a JSON object where the keys are the configuration options and the values are the values for those options. You can see the exact options in the API schema.

​

6/26/2025

• Support multiple output formats for one doc by passing them as comma-separated values in output_format for marker.
• Complete redesign of the dashboard, with a new look and feel. This will also make it easier for us improve functionality in the future.

​

6/18/2025

• Improve the playground to make it more functional (easier to test options)
• Significantly improve styling in the playground
• Add a public version of the playground to make marker easier to test

​

6/3/2025

• Initial launch of playground, for testing marker parsing configurations

​

5/27/2025

• New OCR model which benchmarks better overall, handles inline math, gives detailed character bboxes.
• Add format_lines flag to marker to add inline math and formatting to lines. (this will automatically OCR lines that need it, also)

​

3/26/2025

• Add support for multiple file formats - spreadsheets, epub, html, in addition to existing document, image, pdf, and presentation formats.
• Improve inline math and formatting when passing use_llm.
• use_llm (the high accuracy mode) now costs the same as regular inference.

​

1/30/2025

Marker:

• Integrate a new table recognition model, which handles rowspans and colspans better. This is a significant improvement on the old model.
• Improve the --use_llm option to merge tables across pages, OCR handwriting, OCR forms, and generally have much higher quality than before.
• Integrate a new LaTeX OCR model that is significantly more accurate.
• Add links and references to the markdown - the references include internal links.

General:

• Speed up inference time.
• Remove the line detection endpoint - it had low usage.
• Improve the table_rec endpoint - it now takes the --use_llm flag, and should run much faster.

​

1/3/2025

• Add the use_llm option to the marker API - this uses an LLM to make conversion much more accurate for tables, forms, inline math, and complex pages. It’s a beta feature, and will currently double the cost per request.
• Added other options to the marker endpoint.
  • Use disable_image_extraction to disable image extraction for marker.
  • Use strip_existing_ocr to strip all existing OCR text and re-OCR (if it was added by something like tesseract)
• Better automatic heuristics for when to OCR with marker.
• Better text extraction and layout detection for marker.
• Speed up the marker and OCR endpoints by ~30%.

​

12/4/2024

• Uploaded files can now be up to 200MB in size.
• Improved speed by optimizing file handling on the backend.

​

12/3/2024

• We now offer $5 in free credits to new signups
• Additional bugfixes to improve markdown output quality

​

12/2/2024

• We sped up file operations internally, which should result in a decent API speed boost
• We now handle blockquotes and nested lists with the marker endpoint

​

11/27/2024

• Marker is now at v1, with a lot of improvements - it’s 4x faster than a month ago, and quality is much higher across all document types
• The layout model has been upgraded to a new version, with more potential prediction types

​

10/31/2024

• Bump concurrency/rate limits to 200.
• Improve stability of service under load.
• If you cancel, you will now retain your credits until the end of the month.
• Visual improvements on the marketing site.

​

10/28/2024

• Significant API speedups, on the order of 40% faster.

​

10/25/24

• Flatten form fields into pdf when extracting tables and markdown
• Fix page separators, they now appear at the start of every page, and include a page number

​

10/23/24

• Speed up marker, layout, and detection by 20-30%
• Fix various bugs that cause edge case errors in conversion
• Increase concurrent request limit to 100

​

10/21/24

  • Include header levels like h1, h2, etc.
  • Parse tables very accurately
  • Improve block type detection and markdown quality
  • Fix many output bugs
• Add in new table recognition model at the /table_rec endpoint
  • This will detect and convert tables into a given format
• Improve OCR, layout, text detection quality

• Increase concurrent request limit to 50.

​

7/6/2024

• Major infrastructure stability improvements.

​

7/3/2024

• Added response caching for up to 1 hour. If you send the same document to the same endpoint, with the same options, within that time, you’ll get a cache hit and won’t be billed again.

​
