IBM Releases Granite 4.1 LLM Family Under Apache 2.0

IBM released the Granite 4.1 family of LLMs in 3B, 8B, and 30B parameter sizes under the Apache 2.0 license. The Granite team published a detailed write-up on the training process; Unsloth has already released 21 GGUF quantized variants of the 3B model, ranging from 1.2 GB to 6.34 GB.

The Apache 2.0 license allows unrestricted commercial use, making Granite 4.1 a viable option for enterprises that require open-weight models for data sovereignty, on-premise deployment, or cost reasons.
