Why the edge:
- Risk, LongCat-2.5 +25: LongCat-2.5 60 (File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository.); MiniMax-M3.1-Flash 35 (File safety earns 15, safetensors only, less 10 because the SGLang route the card links passes trust_remote_code for the repository's configuration and processo…)
- Reach, MiniMax-M3.1-Flash +20: LongCat-2.5 35 (Memory 0, the smallest build is Meituan's W4A4 repository, 1,336 GB, and 1,336 GB × 1.2 = 1,603 GB, far above 256 GB.); MiniMax-M3.1-Flash 55 (Memory earns nothing.)
- Agent interface, LongCat-2.5 +5: LongCat-2.5 75 (Chat template 20, chat_template.jinja in the repository (11,823 characters), with a copy in tokenizer_config.json.); MiniMax-M3.1-Flash 70 (The chat template earns 20 for chat_template.jinja in the repository.)
- Documentation and upkeep, LongCat-2.5 +5: LongCat-2.5 46 (Model card 11, Intended use, limitations (the usage considerations), the architecture and the parameter counts are on the card.); MiniMax-M3.1-Flash 41 (The model card earns 11, missing limitations, languages and a knowledge cut-off.)
