About

Cosine is an AI-powered software engineering platform that enables developers and engineering teams to automate coding workflows, run autonomous development tasks, and manage complex software projects across cloud and local environments. Through its cloud platform, developers can delegate coding tasks to AI agents that independently research, write, test, and iterate on code while operating in secure, isolated MicroVM environments. The platform supports multiple operational modes, including autonomous execution, planning, collaborative agent swarms, and manual review workflows, allowing teams to balance automation with human oversight. By combining parallel agent execution, remote infrastructure access, and model-agnostic support for leading AI models, Cosine helps organizations accelerate software delivery while maintaining control, security, and code quality.

About

Reason is an autonomous software engineer and AI coding agent designed to take ownership of real engineering work, from researching codebases and fixing bugs to implementing features and verifying results. It works across connected repositories, local computers, and cloud environments, allowing developers to delegate tasks without interrupting their workflows. The agent can explore codebases, trace call paths, reproduce failures, edit files, run tests, and produce verified pull requests for human review. Its research capabilities provide evidence-backed findings with citations linking directly to source files and lines, while repository memory preserves knowledge for future sessions. Reason supports parallel subagents, isolated workspaces, scheduled sessions, and automated workflows for development and operations. Teams can connect repositories, manage permissions, inspect code changes, and review builds, regression tests, and deployment checks before merging.
