Carbon-X and Granite 4.2 8B score within a point of each other on agent readiness, 61 (C) and 61 (C). Granite 4.2 8B leads on reach, agent interface and documentation and upkeep. Both do open-weight models you run yourself.

- Carbon-X: C 61, rank #42 of 160 open-weight models · https://www.anchorterminal.com/tools/carbon-x.min.md
- Granite 4.2 8B: C 61, rank #66 of 160 open-weight models · https://www.anchorterminal.com/tools/granite-4-2-8b.min.md
- Carbon-X, good for Agents that need a second opinion on DNA variants and regulatory regions on a 16 to 24 GB machine, without sending sequences to a hosted model. Ahead on Risk, 65 against 55.
- Granite 4.2 8B, good for Agents that want a documented, signed, Apache 2.0 reasoning model with tool calling on a 16 GB machine Ahead on Reach, 95 against 90; Agent interface, 85 against 35; Documentation and upkeep, 92 against 72.

Why the edge:
- Agent interface, Granite 4.2 8B +50: Carbon-X 35 (Chat template 20, a Jinja file in the repository.); 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.)
- Documentation and upkeep, Granite 4.2 8B +20: Carbon-X 72 (Model card 17, everything but a knowledge cut-off.); 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…)
- 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 8B 55 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).)
- Reach, Granite 4.2 8B +5: Carbon-X 90 (Memory 30, the publisher's Q4_K_M GGUF is 9.6 GB, or 11.6 GB with a fifth added.); 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.)
