Cosine AI

Cosine is a UK based AI research lab that trains its own coding models and builds software engineering agents on top of them. Its Lumen model family, offered in Scout, Outpost and Sovereign variants, is trained on real production code with the stated goal of maintainable, readable output rather than volume, and is post trained for enterprise and less common languages including COBOL, Fortran, Verilog, Rust and complex SQL. The product targets engineering organisations, particularly those in regulated or security sensitive environments. Developers can work through the Cosine CLI, a terminal interface with a local to remote execution model, tool access over MCP and multi agent orchestration, or through Cosine Cloud, which runs several coding tasks in parallel and lets engineers, product managers and stakeholders collaborate on planned changes in a shared project. Deployment options run from the fully managed public cloud to a managed single tenant environment and fully air gapped installations. A Red Team application is also listed, with a training product marked as coming soon. Pricing is published on a credit basis. Starter costs from $19 per month with 4M credits and add on credits at $6.50 per 1M. Team is $199 per month with 47M credits and add ons at $5.00 per 1M. Enterprise is $999 per month with 240M credits and add ons at $4.50 per 1M. Credits cover agent work, model calls and cloud execution, and private or air gapped deployments are scoped with sales. Cosine has repositioned itself around sovereign AI and has published an open letter on sovereign AI for the United Kingdom.
