It is specifically trained to convert documents into clean Markdown files, well suited for RAG applications. It generates thinking tokens to figure out the layout of the document before generating the Markdown file. It is particularly good at understanding documents with weird layouts and complex tables. The number of thinking tokens can vary from 20% to 500% of the final answer, depending on the task difficulty. **NuMarkdown-8B-Thinking** is a fine-tune of **Qwen 2.5-VL-7B** on synthetic Doc &rarr; Reasoning &rarr; Markdown examples, followed by an RL phase (GRPO) with a layout-centric reward. Try it out in [the 🤗 space!](https://huggingface.co/spaces/numind/NuMarkdown-8b-Thinking) ## Results **NuMarkdown-8B-Thinking** is outperforming generic non-reasoning models like GPT-4o and specialized OCR models like OCRFlux. It is competitive against large reasoning closed-source models like Gemini 2.5. ### Arena ranking against popular alternatives (using trueskill-2 ranking system, with around 500 model-anonymized votes): <p align="center"> | Rank | Model | μ | σ | μ − 3σ | | ---- | --------------------------------------- | ----- | ---- | ------ | | 🥇 1 | **gemini-flash-reasoning** | 26.75 | 0.80 | 24.35 | | 🥈 2 | **NuMarkdown-reasoning** | 26.10 | 0.79 | 23.72 | | 🥉 3 | **NuMarkdown-reasoning-w/o\_grpo** | 25.32 | 0.80 | 22.93 | | 4 | **OCRFlux-3B** | 24.63 | 0.80 | 22.22 | | 5 | **gpt-4o** | 24.48 | 0.80 | 22.08 | | 6 | **gemini-flash-w/o\_reasoning** | 24.11 | 0.79 | 21.74 | | 7 | **RolmoOCR** | 23.53 | 0.82...
