AI engineering that stays under your control
Cosine helps regulated teams use AI coding agents without sending source code, prompts, logs, or engineering context outside approved environments.
AI is becoming essential. Standard deployment models are not keeping up.
Regulated teams cannot always use cloud-hosted models. The risk is not only where the model runs. It is where code is sent, where prompts are stored, how tools execute, who can access logs, and how generated changes are reviewed.
Code cannot leave approved environments
Sensitive repositories, tickets, logs, and system context may be restricted by law, policy, contract, or internal security controls.
Generic agents are hard to govern
Teams need control over identity, permissions, tool execution, audit logs, retention, and human approval.
Low-quality output creates operational risk
AI-generated code must be maintainable, reviewable, testable, and aligned with existing architecture.
Leading the UK sovereign AI story
Lumen Sovereign is being developed for organizations that need frontier-capable AI while keeping control over where models run, how data is governed, and how systems are deployed.
Co-designed with major UK institutions
Coalition members will help define the use cases, security requirements, and governance standards Lumen Sovereign must meet.
Training on UK sovereign compute
Lumen Sovereign is being developed using compute awarded through the UK Government’s Sovereign AI program, with training on Isambard-AI.
Frontier capability for sovereign AI
Lumen Sovereign is being developed for complex work in regulated environments, combining frontier-level ambition with UK-controlled training, governance, and deployment.
Cosine brings AI engineering into the environment your security model requires
Deploy where your code is allowed to live
Use Cosine in managed cloud, dedicated tenant, VPC, or fully air-gapped environments when required.
Keep humans in the review loop
Cosine agents can research, plan, edit, test, and verify changes. Engineers stay in control of review and approval.
Control the agent workflow
Cosine is not just a model endpoint. It combines an owned agent harness, repository context, tool execution, and visible engineering workflows.
Secure deployment
Start with architecture, then prove it on real work
Architecture review
Map code sensitivity, deployment requirements, identity, network boundaries, logging, and approval workflows.
Controlled pilot
Select a representative repository and task set: bug fixes, tests, documentation, refactors, or modernization.
Security and workflow validation
Review repository access, agent permissions, logs, tool execution, model/backend options, and human approval.
Deployment plan
Choose the right production path: managed cloud, dedicated tenant, VPC, sovereign cloud partner, or air-gapped deployment.
Bring AI coding into environments where generic tools cannot go
Cosine helps regulated engineering teams adopt AI software engineering while keeping control of source code, infrastructure, workflows, and review.
Sovereign AI FAQ
Lumen Sovereign is coming soon. Cosine can still support controlled deployment, evaluation, and model strategy today.
Cosine can support fully air-gapped deployment paths for organizations that cannot allow code or development context to leave their environment.
No. Hosting matters, but the workflow matters too. Repository access, logs, permissions, tool execution, review, updates, and auditability all need control.
