Sovereign AI models and autonomous coding agents for regulated, secure environments
A family of frontier LLMs trained on the UK's Isambard-AI supercomputer and specialised for UK and EU regulatory frameworks, legacy programming languages and mission-critical workflows, with 1T and 200B parameter variants announced.
Run Cosine fully air-gapped inside your own infrastructure, in a dedicated managed single-tenant environment, or through Cosine's managed public cloud—with data handling and access controls set by you.
Agent surfaces that cover terminal-driven engineering tasks, everyday desktop research and document work, and long-running parallel jobs in isolated cloud environments.
Designed for defence, government and critical national infrastructure teams that need frontier reasoning inside disconnected networks.

Write code with precision, hand bigger jobs to agents, and keep working from anywhere
Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.
