IBM Granite 4.1 8B vs MiMo-V2.5-Pro

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.

Per the published LICENSE file, MiMo-V2.5-Pro ships under MIT, so the weights themselves carry no commercial restriction. The remaining EU-readiness gaps are the China-based vendor and the corpus disclosure that names training-stage categories (text pre-training, multimodal pre-training, SFT, RL, MOPD) without listing datasets — both should be addressed in any GPAI deployer file before regulated use.
