Granite 4.1

Granite 4.1 is IBM's open Granite model family/collection. IBM's exact Granite 4.1 language-model page defines it as dense language models in 3B, 8B, and 30B sizes, each with base and instruction-tuned variants and Apache 2.0 licensing; IBM Research also describes the broader 4.1 release as spanning language, speech, vision, embedding, and Guardian models for enterprise AI workflows.
