One of the cleanest licensing stories among strong open-weights releases: many Qwen checkpoints ship under Apache 2.0. For most SaaS products, that is about as clean as it gets. - The catch, as always: check your specific version. The Qwen family is big and licensing varies across releases and sizes. - Fine-tunes stack licenses: check the fine-tune's terms and the base model's. Both apply. - Using Qwen through a third-party API? The provider's terms layer on top of the model license. Read both; the stricter governs. - When the paperwork is this clean, clearance is mostly documentation: which checkpoint, which license. Do that and move on. I track license terms per model version across 200 models, and PrivateLLM deploy sets up the licensed model on your own AWS for $50 plus usage.
