Cosine is a Human Reasoning Lab dedicated to codifying human reasoning and applying it to complex problems, with a primary focus on software engineering. Their flagship product, Genie, is an AI-driven, fully autonomous software engineering model designed to function as a collaborative team member. Genie integrates seamlessly with existing codebases and ticketing systems, enabling it to autonomously handle tasks from a project's roadmap or backlog. Unlike traditional tools, Genie operates asynchronously in its own environment, allowing developers to concentrate on more critical work without interruption. Built from the ground up as a truly autonomous system, Genie is equipped with purpose-built tooling that scales effectively.
