Granite 4.1 8B remains a dense 8B transformer despite its 131,072-token context. IBM documents fill-in-the-middle and lists twelve supported languages including German, English, French, Japanese, and Chinese.
The model card describes GQA, RoPE, SwiGLU, and RMSNorm as core architectural pieces, while also warning that multilingual performance can differ from English across languages. Apache 2.0 permits reuse of the weights.
