Cosine

Specialized coding models and agents for cloud and private development environments

Meet Cosine

Cosine develops coding models and agents for engineering teams working with complex software systems. Its Lumen models focus on software development, including established enterprise languages and less common stacks. Developers can use a terminal interface with MCP tools or a shared cloud workspace for planning changes and running coding tasks in parallel.

Organizations can choose a managed public cloud, a dedicated tenant, or an air-gapped deployment within their own infrastructure. The platform is designed for teams that need code generation, codebase understanding, and collaborative engineering workflows under specific security constraints. Cosine also publishes evaluations covering niche languages, implementation quality, and the cost of completing development tasks.
