IBM Releases Granite 4.2: Bringing Native Reasoning and Agentic RL to Open Enterprise Models

IBM has released Granite 4. 2, a family of open reasoning language models in 3B, 8B, and 30B sizes, all under Apache 2. 0. Every model exposes a thinking / low-effort / non-thinking switch and native tool calling.

The 8B and 30B additionally go through an agentic RL block that trains them to edit code, drive a terminal, and run web searches inside real sandboxed environments. The 30B reports 57. 00 on SWE-Bench Verified and 29. 24 on Terminal-Bench 2. 1. The post IBM Releases Granite 4.
