What happened: Granite 4.2 LLMs: How They're Built

IBM released Granite 4.2, a family of reasoning-focused language models in three sizes: 3B, 8B, and 30B parameters, trained on 15 trillion tokens.

Why it matters: Granite 4.2 LLMs: How They're Built

Engineers building reasoning systems, code agents, or tool-using assistants should evaluate these models for their specific deployment and performance needs.

The 8B and 30B models receive additional agentic reinforcement learning that the 3B lacks; capability differences between sizes may be significant for agent tasks.
