Why the edge:
- Documentation and upkeep, Granite 4.2 8B +58: 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…); Qwen3.5-4B 34 (The card covers five of the seven items and misses limitations and a cut-off (14).)
