Why the edge:
- Reach, Granite 4.2 3B +55: Granite 4.2 3B 95 (Memory earns the full 30, since IBM's 4-bit MLX build is 2.07 GB and Ollama's Q4_K_M build 2.2 GB, about 2.5 to 2.6 GB with the fifth added.); Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.)
- Documentation and upkeep, Granite 4.2 3B +41: Granite 4.2 3B 92 (The card covers everything but a knowledge cut-off (17).); Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.)
- Agent interface, Granite 4.2 3B +20: Granite 4.2 3B 85 (The template ships in the repository (20).); Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.)
- Risk, Granite 4.2 3B +5: Granite 4.2 3B 55 (File safety gets 15 of 25, safetensors only, less 10 because the card's vLLM command loads the repository's parser plugin.); Kimi K3.1 Pro 50 (File safety 15, safetensors only, less 10 for remote code and prompts built by the repository's script.)
