Key Facts
- Fact 1: The newly launched Granite 4.2 comes in 3B, 8B, and 30B parameter variants.
- Fact 2: These new releases offer a 128,000-token context window natively.
- Fact 3: The 8B and 30B variants (not the 3B one) also go through an agentic reinforcement learning block; they were trained for expanded capabilities like using the terminal, searching the web, or using external tools.
- Fact 4: The 3B model supports tools too, but without the same level of specialized training.

Like previous versions, IBM is taking a decoder-only approach here. These new releases offer a 128,000-token context window natively. The 8B and 30B variants (not the 3B one) also go through an agentic reinforcement learning block; they were trained for expanded capabilities like using the terminal, searching the web, or using external tools.
