Cosine

Cosine is a coding agent that ships across three surfaces — a CLI in your terminal, a native macOS desktop app, and a cloud runner for isolated task execution — with shared codebase awareness and a visibility-first UX. The underlying agent (Genie) is known for topping SWE-Bench at launch and is pitched at engineers who want autonomous task execution without the "slop" — plus enterprise teams who need VPC, on-prem, or air-gapped deployments. Paid product with self-serve and enterprise tiers; VS Code extension also available.
