IBM released Granite 4.2 as dense reasoning models at 3B, 8B and 30B under Apache 2.0 with 512K context.

Published August 25, it's IBM's 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 (Hugging Face). The r/LocalLLaMA thread reached 376 upvotes with top comments conceding Granite trails on benchmarks but valuing the permissive license. IBM also released a 470M Apache-2.0 ASR model claiming 12,600 RTFx on one H200.
