Cosine AI
Hand off complex coding tasks without sacrificing maintainability or visibility.

Cosine AI is an autonomous coding agent and family of production-first models (Lumen) designed for real engineering work on complex, long-lived codebases. It works across desktop, cloud, and terminal environments, supporting enterprise and niche programming languages. The platform offers flexible deployment options from public cloud to fully air-gapped setups for organizations with strict compliance requirements.
Cosine's Lumen models are trained on production code with behavioral reinforcement learning and deployed as an autonomous engineering agent accessible via desktop app, cloud, or CLI.
