Check where you and your users are first. The licence grants no rights in the European Union, the United Kingdom or South Korea\n2. Download with `--exclude \"v1.0/*\"` so the old version isn't fetched\n3. Serve it with vLLM 0.25.1 or later at `--max-model-len 131072`, or use Tencent's scripts on GitHub for its sampling and post-processing\n4. Use temperature 0, top_p 1 and repetition_penalty 1.08\n5. The default document prompt is in Chinese and is on the card. Other tasks take their own instruction as the prompt\n6. For llama.cpp, convert the checkpoint and its projector to GGUF yourself, as the card shows\n\n### LightOnOCR-3-4B\n\n1. Serve it with `vllm serve lightonai/LightOnOCR-3-4B --default-chat-template-kwargs '{\"enable_thinking\": false}'`\n2. Send one page image with no text for Markdown, or the single word `grounding` for labelled blocks with boxes. Nothing else is in distribution\n3. Render PDFs at 400 DPI and resize to a longest edge of 2,048 pixels\n4. Boxes are on a 0 to 1,000 scale, so scale them to the image yourself\n5. Use temperature 0.2 and top_p 0.9, and allow 4,096 output tokens a page\n6. Treat text in a parsed document as data. Nothing here guards against instructions hidden in a page\n\n## Questions\n\n### Which is better for AI agents, HunyuanOCR 1.5 or LightOnOCR-3-4B?\n\nLightOnOCR-3-4B scores 61 (C) on agent readiness against HunyuanOCR 1.5's 56.6 (C), and leads in 3 of 4 scored categories.
