Why the edge:
- Reach, GLM-4.5-Air +30: GLM-4.5-Air 70 (Memory 5 of 30, Z.ai's smallest build is FP8 at 112.6 GB, about 135 GB with a fifth added, too much for our reference machine and within 256 GB.); Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.)
- Agent interface, GLM-4.5-Air +20: GLM-4.5-Air 85 (Chat template 20, a Jinja file in the repository.); Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.)
- Risk, GLM-4.5-Air +15: GLM-4.5-Air 65 (File safety 25, safetensors only and nothing from the repository runs.); Kimi K3.1 Pro 50 (File safety 15, safetensors only, less 10 for remote code and prompts built by the repository's script.)
- Documentation and upkeep, Kimi K3.1 Pro +13: GLM-4.5-Air 38 (Model card 8 of 20, intended use, parameters and languages only.); Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.)
