Cosine: The Future of Autonomous Software Development

Cosine is a cutting-edge AI coding agent built by developers for developers, designed to automate complex, real-world software tasks directly within live production codebases. As a leading agentic system, it operates end-to-end without human supervision, intelligently breaking down large, abstract development challenges into structured subtasks through its powerful AutoPM feature. Powered by the proprietary Genie 2 model, Cosine achieves a 72% pass rate on the rigorous SWE-Lancer benchmark—surpassing OpenAI and Anthropic—demonstrating its ability to handle production-grade coding with human-like precision. Seamlessly integrating with tools like Slack, Jira, and Linear, Cosine enables asynchronous task management, letting developers assign multiple tickets and return later to review and merge pull requests. With fine-tuning support for GPT-4o and proven performance across 237 real-world tasks valued at $236k, Cosine is redefining efficiency and autonomy in software engineering.
