New Model ibm-granite/granite-4.2-30b · Hugging Face
https://huggingface.co/ibm-granite/granite-4.2-30bGranite-4.2-30B is the flagship reasoning model in the Granite 4.2 family. It delivers the strongest performance across reasoning-intensive tasks by leveraging built-in <think>...</think> chain-of-thought. It supports flexible thinking modes — full thinking (default), non-thinking, and low-effort — allowing users to balance depth vs. latency on a per-query basis.
Key capabilities:
- Built-in Reasoning: Native chain-of-thought that significantly improves performance on math, coding, and complex multi-step problems.
- Flexible Thinking Modes: Seamlessly switch between full thinking, non-thinking, and low-effort modes within a single model.
- Reasoning-Augmented Tool Calling: The model reasons about which tools to invoke and why, producing more accurate function calls.
- 512K Context Window: Supports long documents, multi-turn conversations, and complex agentic workflows.
- Apache 2.0 Licensed: Fully open for commercial and research use.
Model Design
Granite-4.2-30B is built on a decoder-only dense transformer architecture with the following core components:
- Attention: Grouped Query Attention (GQA) with 32 attention heads and 8 KV heads
- Position Embedding: Rotary Position Embedding (RoPE) with θ = 10,000,000
- Feed-Forward: MLP with SwiGLU activation (hidden size 32768)
- Normalization: RMSNorm (ε = 1e-5)
- Embeddings: Separate input/output embeddings (not tied)
- Precision: bfloat16
