Given a document page image, it generates a Markdown transcription in natural reading order — text, formulas (LaTeX), tables (HTML), and visual regions (bounding-box image tags). It scores 96.58 on OmniDocBench v1.6, state of the art for an end-to-end model, and an Avg3 of 75.06 on PureDocBench. ## Architecture | | | |---|---| | Base model | OvisOCR2 (Qwen3.5-VL arch, `Qwen3_5ForConditionalGeneration`, ~0.8B params) | | Quantization | MX FP8 (micro-scaled 8-bit float) | | Bits per weight | 9.168 | | Disk size | 958 MB (from ~1.6 GB bf16) | | Format | MLX (safetensors) | ## Usage ```python from mlx_vlm import load, generate from mlx_vlm.prompt_utils import apply_chat_template from mlx_vlm.utils import load_config model_path = "sahilchachra/ovisocr2-mxfp8-mlx" model, processor = load(model_path, trust_remote_code=True) config = load_config(model_path, trust_remote_code=True) prompt = ( "\nExtract all readable content from the image in natural human reading order " "and output the result as a single Markdown document.
