Fully Agentic SWE
Cosine is a fully agentic SWE that allows you to instantly work on every single ticket at once, asynchronously.
Cosine positions itself as an AI engineer for production software teams, focusing on a coding model trained on real production code to deliver maintainable code and faster shipping. The platform offers a multi-surface experience (Cosine app, desktop, terminal) with deployment options from cloud to air-gapped on-premises and emphasizes security, ownership, and production workflows.
Cosine provides Lumen, a coding model system trained on real production code to optimize for writing better software. The product suite includes a browser/desktop app for collaborative coding, a terminal-based workflow with local-to-remote execution, and multi-agent orchestration. It supports deployment options from Cosine Cloud (public cloud) to fully private deployments (single-tenant, VPC, air-gapped) and enterprise environments, with models (Scout, Outpost, Frontier) suited for different coding tasks and scales. Pricing is based on Cosine credits representing usage of agent work, model calls, and cloud execution, with starter, team, and enterprise plans and optional private deployments.
Who it’s for: Engineering teams and organizations responsible for production software development and deployment, including individual developers, professional engineering teams, and enterprises seeking private deployment or air-gapped security.
Pricing page references enterprise deployments and private deployments; mentions of private tenants, air-gapped options, and sales talks imply active go-to-market and enterprise traction.
