Why the edge:
- Documentation and upkeep, Arete-27B +12: Arete-27B 63 (Model card 8, no limitations, context length, languages or cut-off.); Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.)
- Reach, Arete-27B +10: Arete-27B 50 (Memory 10, the only build from Nous Research is the 54.7 GB BF16 release, which needs about 66 GB and fits the reference machine.); Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.)
- Risk, Arete-27B +5: Arete-27B 55 (File safety 25, safetensors only and no remote code.); Kimi K3.1 Pro 50 (File safety 15, safetensors only, less 10 for remote code and prompts built by the repository's script.)
- Agent interface, Kimi K3.1 Pro +5: Arete-27B 60 (Chat template 20, a Jinja file in the repository.); Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.)
