About

What is Cosine AI?

Cosine AI is an advanced AI software engineering agent designed to streamline complex coding tasks without compromising maintainability or visibility. It operates across desktop, cloud, and terminal environments, integrating seamlessly into existing workflows. Cosine AI utilizes its proprietary Lumen models, optimized for production-first coding, focusing on maintainable, readable, and production-quality outputs rather than bloated code. It excels at reasoning across intricate architectures, legacy infrastructure, and diverse codebases, including enterprise and niche languages like COBOL, Fortran, Verilog, Rust, and complex SQL. The platform supports the entire SDLC, from work scoping and development to testing and deployment, offering flexible deployment options including public cloud, dedicated tenant, and fully air-gapped solutions for stringent security requirements.

FAQs

What are Cosine Credits and how are they used?

Cosine Credits are the currency used to run agents within the platform. Every action, such as reading code, planning solutions, or writing output, consumes credits from your team's monthly pool. Hobby seats include 5M credits, while Professional seats include 60M credits per month. Unused credits do not roll over.

What happens if my team runs out of Cosine Credits?

If your team's credit balance is exhausted, Cosine will pause new agent inference until the balance is replenished. You can purchase credit top-ups instantly from your billing settings to resume work, or wait for your monthly credit pool to renew at the start of the next billing cycle.

How is Cosine AI trained, and is customer data used?

Cosine AI is trained on publicly available open-source repositories and is not trained on customer data or private code repositories. The company maintains enterprise agreements with all AI vendors to ensure no data sent to them is used for training purposes, and users retain full ownership of their projects and code.

What deployment options does Cosine AI offer for enterprises?

Cosine AI offers flexible enterprise deployment options including public cloud for standard controls, managed single-tenant cloud for private environments with enterprise controls, and fully air-gapped deployments for organizations requiring maximum isolation and no external dependencies.
