Why the edge:
- Documentation and upkeep, Nanbeige4.2-3B +31: MiniMax-M3.1-Flash 41 (The model card earns 11, missing limitations, languages and a knowledge cut-off.); Nanbeige4.2-3B 72 (Model card 17, Intended use, limitations, the architecture, the parameters (3B outside the embeddings), the context and the languages (in the metadata) are on t…)
- Reach, Nanbeige4.2-3B +30: MiniMax-M3.1-Flash 55 (Memory earns nothing.); Nanbeige4.2-3B 85 (Memory 30, the smallest build from Nanbeige is the FP8 repository (the 8-bit GPTQ one is the same size), 5.19 GB, and 5.19 GB × 1.2 = 6.2 GB, within 16 GB.)
- Risk, Nanbeige4.2-3B +20: 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…); Nanbeige4.2-3B 55 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).)
- Agent interface, Nanbeige4.2-3B +15: MiniMax-M3.1-Flash 70 (The chat template earns 20 for chat_template.jinja in the repository.); Nanbeige4.2-3B 85 (Chat template 20, A Jinja chat template in tokenizer_config.json (7,961 characters), with enable_thinking, preserve_thinking, tools and tool_call_format switche…)
