Why the edge:
- Agent interface, Nanbeige4.3-33B +25: Nanbeige4.3-33B 85 (The chat template earns 20, Jinja in tokenizer_config.json.); ZAYA1-8B 60 (Chat template 20, chat_template.jinja in the repository (10,700 characters).)
- Documentation and upkeep, Nanbeige4.3-33B +6: Nanbeige4.3-33B 56 (The model card earns 11, with intended use, parameters, context and languages but no limitations, architecture or cut-off.); ZAYA1-8B 50 (Model card 5, Intended use and the parameter counts are on the card.)
- Risk, Nanbeige4.3-33B +5: Nanbeige4.3-33B 60 (File safety earns 25, safetensors only and no repository code, so the card's trust_remote_code has nothing to run.); ZAYA1-8B 55 (File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository.)
