Why the edge:
- Documentation and upkeep, LightOnOCR-3-4B +26: LightOnOCR-3-4B 51 (Model card 11, Intended use, a limitation (instructions other than its two prompts are out of distribution), the architecture (Qwen 3.5's) and the size (4B) are…); Nanonets-OCR2-3B 25 (Model card 5, Intended use and the languages are on the card.)
- Reach, LightOnOCR-3-4B +15: LightOnOCR-3-4B 70 (Memory 30, the only build from LightOn is the BF16 safetensors file, 9.08 GB, and 9.08 GB × 1.2 = 10.9 GB, within 16 GB.); Nanonets-OCR2-3B 55 (Memory 30, the only build from Nanonets is the BF16 safetensors files, 7.51 GB, and 7.51 GB × 1.2 = 9.0 GB, within 16 GB.)
- Risk, LightOnOCR-3-4B +15: LightOnOCR-3-4B 55 (File safety 25, one safetensors file, no .bin, .pt or .pth files and no Python in the repository.); Nanonets-OCR2-3B 40 (File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository.)
