# Technology & Quality

- [Is Cosine an autonomous software engineer or a copilot?](/faqs/technology-and-quality/is-cosine-an-autonomous-software-engineer-or-a-copilot.md): Cosine is an autonomous software engineer, not a copilot. It plans, writes, and tests code independently — delivering ready-to-review pull requests without constant human supervision.
- [What tasks can Cosine complete end-to-end?](/faqs/technology-and-quality/what-tasks-can-cosine-complete-end-to-end.md): Cosine autonomously completes end-to-end engineering tasks — from bug fixes and feature builds to refactoring, tests, and documentation — delivering ready-to-review pull requests.
- [How does Cosine minimise hallucinations and ensure code quality?](/faqs/technology-and-quality/how-does-cosine-minimise-hallucinations-and-ensure-code-quality.md): Cosine minimises hallucinations through rigorous evaluation, testing, and guardrails — verifying every output against the existing codebase before creating a pull request.
- [How Cosine’s model was trained](/faqs/technology-and-quality/how-cosines-model-was-trained.md): Cosine’s proprietary Genie model is purpose-built for software engineering — trained on open-source code and refined with reinforcement learning for autonomy, reasoning, and code correctness.
- [What benchmarks or case studies exist?](/faqs/technology-and-quality/what-benchmarks-or-case-studies-exist.md): Cosine has demonstrated proven results across real-world enterprise deployments and benchmarks — improving PR completion time by 40% and outperforming comparable code reasoning models.
