Why the edge:
- Agent interface, Nemotron 3 Ultra 550B A55B +40: Nemotron 3 Ultra 550B A55B 90 (The chat template earns 20, a Jinja file in the repository.); Qwen-AgentWorld-35B-A3B 50 (Chat template 20, chat_template.jinja in the repository, the same as the template in tokenizer_config.json.)
- Documentation and upkeep, Nemotron 3 Ultra 550B A55B +29: Nemotron 3 Ultra 550B A55B 70 (The model card earns 20, all seven items with limitations in the linked subcard.); Qwen-AgentWorld-35B-A3B 41 (Model card 11, the card gives intended use (simulating agent environments), architecture, parameters and context length.)
- Risk, Nemotron 3 Ultra 550B A55B +15: Nemotron 3 Ultra 550B A55B 70 (File safety earns 15, safetensors only but with 10 off because the documented commands pass trust-remote-code and the repository ships Python files.); Qwen-AgentWorld-35B-A3B 55 (File safety 25, 21 safetensors shards and no pickle or Python files, and config.json has no auto_map.)
