Cosine

Cosine is a UK-based AI research lab that trains its own Lumen models and builds autonomous coding agents. Its products include a terminal-based CLI, a cloud product for parallel coding tasks, and dedicated or fully air-gapped deployments. The website says Lumen is post-trained for software engineering, including niche and legacy languages such as COBOL, Fortran, Verilog, Rust and complex SQL.

The stated customers are organisations in finance, healthcare, defence and government that need AI engineering capability behind strict firewalls or without public cloud access. Pricing on the website is subscription-based, with Starter, Team and Enterprise tiers priced per month in credits, plus paid add-on credits; enterprise and private deployments are scoped with sales.

The About page lists the company's history from 2022 and says it is building a UK sovereign AI model alongside an industry coalition. Its current open roles are in go-to-market and machine learning, all listed at the London office. The website lists social profiles on X and LinkedIn and describes an in-office working model.
