Why the edge:
- Reach, Nanbeige4.3-33B +40: Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.); Nanbeige4.3-33B 80 (Memory earns 20, since Nanbeige's INT4 build is 22.57 GB, about 27 GB with a fifth added, which fits 32 GB.)
- Agent interface, Nanbeige4.3-33B +20: Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.); Nanbeige4.3-33B 85 (The chat template earns 20, Jinja in tokenizer_config.json.)
- Risk, Nanbeige4.3-33B +10: Kimi K3.1 Pro 50 (File safety 15, safetensors only, less 10 for remote code and prompts built by the repository's script.); 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.)
- Documentation and upkeep, Nanbeige4.3-33B +5: Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.); Nanbeige4.3-33B 56 (The model card earns 11, with intended use, parameters, context and languages but no limitations, architecture or cut-off.)
