IBM published Granite 4.2 on 2026-08-25, its first family of dense decoder-only reasoning models, with the 30B flagship claiming state-of-the-art resolve rates on SWE-Bench Pro and Terminal-Bench. The 8B and 30B went through an agentic training curriculum on real sandboxes for software engineering, terminal operations, and web research, and all sizes support a 512K context under Apache 2.0. The r/LocalLLaMA thread reached 376 upvotes, with the top comments conceding Granite trails on benchmarks but valuing the permissive license.
