Open source AI models give you full control over your AI stack. Here is why teams choose open weights over proprietary APIs.
Self-host models on your own infrastructure. Your data never leaves your network, meeting strict compliance and privacy requirements.
Open weights mean you can deploy anywhere: on-premises, any cloud provider, or at the edge. Switch infrastructure without changing your model.
Fine-tune open source models on your proprietary data. Adapt architecture, optimize inference, and build domain-specific solutions.
Benefit from global research communities. Open models receive rapid improvements, safety patches, and community-built tooling.
