Why the edge:
- Reach, Nemotron 3 Nano 30B A3B +50: Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.); Nemotron 3 Nano 30B A3B 90 (Memory earns 25 because the smallest 4-bit build is Ollama's NVFP4 MLX build at 18 GB, 21.6 GB with the fifth added, and NVIDIA's own NVFP4 build lands in the s…)
- Documentation and upkeep, Nemotron 3 Nano 30B A3B +29: Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.); Nemotron 3 Nano 30B A3B 80 (The model card earns 20, with all seven items on the card and its subcards.)
- Agent interface, Nemotron 3 Nano 30B A3B +25: Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.); Nemotron 3 Nano 30B A3B 90 (The chat template earns 20 as a Jinja file in the repository.)
- Risk, Nemotron 3 Nano 30B A3B +10: Kimi K3.1 Pro 50 (File safety 15, safetensors only, less 10 for remote code and prompts built by the repository's script.); Nemotron 3 Nano 30B A3B 60 (File safety earns 15, safetensors only but with the documented serving path passing trust-remote-code and loading a reasoning parser file from the repository.)
