Why the edge:
- Agent interface, Granite 4.2 30B +50: Carbon-X 35 (Chat template 20, a Jinja file in the repository.); Granite 4.2 30B 85 (Chat template 20, chat_template.jinja in the repository, with roles, tools, tool responses, the thinking switch and low effort.)
- Documentation and upkeep, Granite 4.2 30B +15: Carbon-X 72 (Model card 17, everything but a knowledge cut-off.); Granite 4.2 30B 87 (Model card 17, Intended use (best for), limitations (ethical considerations and limitations), architecture, parameters (30B), context length (128K native) and 1…)
- Risk, Carbon-X +10: Carbon-X 65 (File safety 15, safetensors and GGUF only, but the documented loading path runs the repository's tokenizer.py through trust_remote_code.); Granite 4.2 30B 55 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).)
