| Summary | ||
| Verdict | Conditional xAI's first open-weights release. Commercial use allowed under the Grok 2 Community License with xAI's Acceptable Use Policy. Notable restriction: weights cannot be used to train other models (distillation ban). 500GB model, needs 8 GPUs with 40GB+. | EU-ready Per Mistral's published license, Mistral Medium 3.5 ships under a Modified MIT License: vanilla-MIT terms for independent developers, startups and most enterprises, with a revenue-threshold carve-out that routes large companies back to a paid commercial agreement. Paris-headquartered vendor with EU jurisdiction end to end and a 256k-token context. Training-data composition is not published in the model card — usual caveat for high-assurance public-sector deployments. |
