Why the edge:
- Agent interface, Step 3.7 Flash +15: Step 3.7 Flash 85 (Chat template 20, chat_template.jinja in the repository (5,723 characters).); WeVisOne-VL-2B 70 (Chat template 20, chat_template.jinja in the repository (5,292 characters), Qwen3-VL's template.)
- Risk, WeVisOne-VL-2B +10: Step 3.7 Flash 45 (File safety 15, safetensors and GGUF only, no .bin, .pt or .pth files (25).); WeVisOne-VL-2B 55 (File safety 15, the backbone is safetensors, but mask_decoder.pt, a PyTorch pickle the card calls a required component, sits beside it.)
- Documentation and upkeep, WeVisOne-VL-2B +9: Step 3.7 Flash 39 (Model card 14, Intended use, the architecture, the parameters, the context and the language (in the metadata) are on the card.); WeVisOne-VL-2B 48 (Model card 8, Intended use, limitations and the architecture are on the card.)
