IBM offers the Granite family of foundation models for enterprise use, which it develops internally and releases under an open-source Apache 2.0 license, with the first models announced in September 2023 and the latest generation (Granite 4.1) released in 2026.

Granite models span multiple modalities: language, code, time series forecasting, speech transcription, vision (document and image understanding), and embedding. IBM also produces Granite Guardian models designed to detect harmful content, bias, hallucinations, and jailbreak attempts in AI systems. The models are available on IBM's watsonx.ai platform and on Hugging Face. IBM provides IP indemnification for enterprise customers using IBM-developed Granite models, and publishes training data documentation as part of its transparency commitment.
