Side-by-side comparison of GPT-OSS 120b (OpenAI · USA) and MiMo-V2.5 (Xiaomi (MiMo)) for self-hosted deployment of the open-weight model. GPT-OSS 120b is rated EU-ready; MiMo-V2.5 is conditional. They part ways on licence: GPT-OSS 120b is "Apache 2.0", MiMo-V2.5 is "MIT".

| Summary | ||
| Verdict | EU-ready OpenAI's first major open-weights release. Apache 2.0, MoE with 5.1B active over 117B total, MXFP4 quantised to fit a single 80GB GPU. Historic shift for a vendor that built its brand on closed weights. | Conditional MiMo-V2.5 is the omnimodal sibling of MiMo-V2.5-Pro — text, vision, audio, and video on a single sparse-MoE backbone, also under MIT. Same posture as the Pro: deployable weights, but the China origin and stage-level training disclosure mean any EU rollout needs self-hosting plus a deployer-prepared GPAI compliance file, with extra attention to Article 50 transparency for synthetic and biometric outputs. |
