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
Co-designed with major UK institutions
Coalition members will help define the use cases, security requirements, and governance standards Lumen Sovereign must meet.
Consulting & Systems integrators
Lumen Sovereign is being developed using compute awarded through the UK Government’s Sovereign AI programme, 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.
