IBM has released the Granite 4.1 family of large language models, comprising 3B, 8B, and 30B parameter versions. These models were trained on approximately 15 trillion tokens through a five-stage pre-training process that included extending the context window to 512K tokens. Further refinement involved supervised fine-tuning on curated data and reinforcement learning. Notably, the 8B instruct model achieves performance comparable to the larger Granite 4.0 MoE model, and all Granite 4.1 models are available under the Apache 2.0 license. AI
