Cosine

Cosine is a UK-based AI research lab building autonomous, reasoning AI that works alongside human engineers to solve the most critical software problems. It builds tools and models designed to operate in messy, existing codebases and regulated environments, delivering secure, enterprise-grade AI capabilities.

Cosine develops surfaces for agentic software engineering across CLI, Desktop, and Cloud. It aims to scale from quick fixes to complex migrations, integrating with existing codebases and workflows while maintaining strong visibility, control, and code quality.

Cosine foregrounds a focused philosophy: a model trained exclusively on real production code, from real engineering teams will outperform a generalist at the task developers actually need. Every training decision and metric is grounded in the objective of better code.

Cosine supports deployments that fit security needs, including public cloud, fully managed single-tenant cloud, fully air-gapped environments, and dedicated tenants, with options to start quickly and scale into private deployments.
