About this launch

The 8B member of IBM's Granite 4.2 family, released 25 August 2026 under Apache 2.0. It scores 47.67 on SWE-bench Verified, which is the interesting number in the family: enough for scoped internal automation, from a model small enough to run where a 30B will not fit. Like the 30B it carries the switchable chain-of-thought reasoning and agentic reinforcement learning trained in sandboxed terminal and coding environments, plus native tool calling.
