Built for controlled deployment

Cosine can support different deployment models depending on the organisation’s security, infrastructure, and governance requirements.

No data egress

Run Cosine where private code and prompts stay inside the boundary you approve.

Model choice

Use Lumen, supported open-weight models, or customer-approved post-trained models.

Auditability

Keep visibility into agent actions, tool use, changes, and review status.

Human review

Every change remains visible, testable, and subject to customer review.
