Why the edge:
- Documentation and upkeep, Granite 4.2 3B +46: Devstral Small 2 46 (Model card 11, Intended use, the architecture, the parameters and the context are on the card.); Granite 4.2 3B 92 (The card covers everything but a knowledge cut-off (17).)
- Agent interface, Granite 4.2 3B +20: Devstral Small 2 65 (Chat template 20, chat_template.jinja in the repository (11,362 characters), with the tokenizer's tekken file for mistral-common.); Granite 4.2 3B 85 (The template ships in the repository (20).)
- Reach, Granite 4.2 3B +5: Devstral Small 2 90 (Memory 25, the smallest build at 4 bits from a runtime's own library is Ollama's devstral-small-2 at Q4_K_M, 15 GB, and 15 GB × 1.2 = 18 GB, within 24 GB.); 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.)
- Risk, Devstral Small 2 +5: Devstral Small 2 60 (File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository.); 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.)
