Cosine

Cosine is an AI software engineering agent designed for maintainability, visibility, and control across every developer surface. It runs in the terminal via CLI, in isolated cloud environments, and as a native macOS desktop app, giving teams the flexibility to work where they already do. Cosine is built by a machine learning research lab that post-trains AI models on high-quality human coding data, achieving state-of-the-art coding accuracy. It supports individual developers, growing teams, and regulated enterprises with deployment options ranging from cloud to fully air-gapped on-premise environments.

• CLI Agent — Install with a single curl command and run Cosine directly in your terminal with full repo understanding and precise execution on macOS, Linux, and Windows.
• Cloud Agents — Run tasks in isolated cloud environments with full step-by-step visibility; sign up and start immediately via the web.
• Desktop App — Download the native macOS app for full codebase awareness, inline review, and autonomous task execution.
• VS Code Extension — Install the Cosine extension from the VS Code Marketplace to bring agent capabilities directly into your editor.
• Parallel Task Execution — Run multiple agent tasks simultaneously (swarms) to accelerate feature development without losing control.
• Enterprise Deployment — Deploy on your own VPC, on-premise, or fully air-gapped; supports custom model weights on your own GPUs.
• Custom Post-Training — Train a model on your own repos, frameworks, or legacy languages like COBOL or Fortran for deep internal context.
• Security & Compliance — SOC 2 attested, ISO 27001 aligned, GDPR and CCPA compliant, with audit logs, role-based access, and zero data leakage.
• Integration with Dev Tools — Assign and execute tasks directly from Jira, Linear, Trello, Asana, GitHub, Slack, and more.
• Token-Based Usage — Each seat includes a monthly token pool; top-ups are available at any time from billing settings.
