Why the edge:
- Documentation and upkeep, Granite 4.2 8B +55: Granite 4.2 8B 92 (Model card 17, Intended use (best for), limitations (ethical considerations and limitations), architecture, parameters (8B), context length (128K native) and 12…); Qwen3.5-0.8B 37 (The card covers six of the seven items, missing only a cut-off (17), because it states the intended uses and warns about thinking loops.)
- Agent interface, Granite 4.2 8B +25: Granite 4.2 8B 85 (Chat template 20, chat_template.jinja in the repository, with roles, tools, tool responses, the thinking switch and low effort.); Qwen3.5-0.8B 60 (The template ships in the repository (20) and the model was trained for tool use with several calls per turn in the template (20).)
- Reach, Granite 4.2 8B +15: Granite 4.2 8B 95 (Memory 30, IBM's own 4-bit MLX build granite-4.2-8b-q4-mlx is 4.95 GB, and 4.95 GB × 1.2 = 5.9 GB, within 8 GB.); Qwen3.5-0.8B 80 (Memory earns the full 30, since LM Studio's Q4_K_M build with its projector is 0.73 GB (0.88 GB with the fifth added) and Ollama's Q8_0 build was 1.0 GB, both f…)
