Cosine Genie 2: The Autonomous AI Software Engineer

What is Cosine Genie 2?

Cosine Genie 2, powered by Cosine's proprietary Genie 2 model, is an AI coding agent designed to automate software development tasks. It aims to function as a self-sufficient AI software engineer capable of working in real production codebases without constant human supervision. Cosine is built by developers, for developers.

How does Cosine Genie 2 work?

Cosine breaks down large tasks into structured subtasks, researches the best approach, and manages multiple agents simultaneously. This asynchronous process allows developers to assign multiple tickets and review pull requests later. Workflow integrations with Slack, Jira, and Linear are available.

Key Features:

  • Agentic: Completes tasks end-to-end without human supervision.
  • Asynchronous: Handles multiple tickets at once.
  • Complex Codebases: Trained to work in real production environments.
  • Workflow Integrations: Integrates with Slack, Jira, and Linear.

Why is Cosine Genie 2 important?

According to Cosine, Genie 2 achieves a 72% pass rate on SWE-Lancer, a benchmark designed for real development work. This outperforms OpenAI and Anthropic and makes Cosine a leading agent for production-grade tasks. The tool enables developers to offload complex and repetitive tasks to an AI agent.

Where can I use Cosine Genie 2?

Cosine is designed to integrate into existing development workflows through tools like Slack, Jira, and Linear. This allows for seamless task assignment and progress tracking. Developers can assign tickets, fix bugs, refactor code, and add features to existing codebases.

Laura Modiano, OpenAI EMEA, states, "Cosine is showing what it looks like when AI starts to work like a real-world developer. Genie 2 uses the latest AI models and customization to mirror how engineers reason through complexity and take action. It’s a foundational leap for software development."
