IBM has published a technical breakdown of Granite 4.2, its first dense, decoder-only reasoning model family, released in 3B, 8B, and 30B sizes. The models are pre-trained on roughly 15 trillion tokens, extended to a 512K-token context window, and post-trained with a multi-stage RL pipeline that includes agentic tool-use training for the 8B and 30B variants.
