Side-by-side comparison of GLM-5.1 (Zhipu AI (Z.ai) · China) and IBM Granite 4.1 8B (IBM · USA) for self-hosted deployment of the open-weight model. GLM-5.1 is rated conditional; IBM Granite 4.1 8B is EU-ready. They part ways on licence: GLM-5.1 is "MIT", IBM Granite 4.1 8B is "Apache 2.0".

| Summary | ||
| Verdict | Conditional Per current documentation, GLM-5.1 is released under a verbatim MIT License with no use restrictions, enabling self-hosted commercial deployment. However, training-data opacity, Beijing-based publisher, and Zhipu AI's presence on the US BIS Entity List create EU AI Act transparency and supply-chain screening risks for regulated deployers. | EU-ready Per the published model card, Granite 4.1 8B is an Apache 2.0 9B-parameter dense decoder with a 131k-token context, sourced from publicly-available datasets, internal synthetic data and human-curated material. IBM continues the unusual-for-the-industry training-data transparency that anchored the Granite 3 family, and offers IP indemnification when the model is consumed via watsonx — a strong default for regulated enterprise pilots that need a defensible weights-available alternative to hyperscaler frontier models. |
