Definition
An AI model whose weights are published and downloadable, allowing it to run on your own infrastructure without depending on its creator's cloud.
An open-weights model (Llama, Mistral, Qwen, DeepSeek, GPT-OSS…) can be downloaded and run anywhere: on a company server, a private cloud, even a workstation. The processed data never leaves the machine, unlike proprietary models accessible only through a cloud API.
The best open models now rival proprietary ones on the majority of business tasks, at a controlled operating cost. They are the keystone of sovereign deployments: even if every American provider cut off their APIs tomorrow, a local model would keep working.
All AI models, deployed on your infrastructure, with your documents connected.
