Architecture, strengths and use cases

Granite 4.1 30B is an official self-hostable IBM release in the IBM Granite General track. It uses GraniteForCausalLM, carries 28.9B, supports a verified context window of 131,072 tokens, and exposes only source-certified checkpoints and runtime combinations. Its release, license and deployment facts are tied to the official repository revision rather than inferred from the family name.

Granite 4.1 30B uses GraniteForCausalLM with 28.9B. The stored architecture profile records 64 layers, hidden width 4096, 32 attention heads and a 131,072 token context ceiling where the official configuration publishes those fields.

License and self-hosting considerations

The full 28.9B resident weight set must fit across the selected GPUs. Context and concurrency add KV-cache memory; MoE active parameters do not replace resident-weight memory.

Granite 4.1 30B is published under apache-2.0. The release-scoped official license link and verification date are retained with the catalogue record.

Commercial Use Allowed. The official license permits commercial use; its obligations still apply.
