What the evaluation found
Github Copilot
Strongest category: Privacy
GitHub Copilot offers a tiered privacy model that provides its strongest guarantees to paying business and enterprise customers. These organizations benefit from a strict zero-retention policy, ensuring their code is not stored or used for training, and are protected by a formal commitment from Microsoft to defend them against copyright lawsuits. For individual users, privacy relies on user-managed settings, as data collection for AI training is on by default until a user actively opts out.

Strongest category: Quality
Replit Agent is a powerful and deeply integrated coding assistant that excels at generating functionally correct code, achieving industry-leading scores on standard programming tests. Its ability to understand an entire project's context allows it to automate complex tasks like writing tests and finding security flaws. However, this power is paired with significant risk, as the code it generates can fail in unexpected ways and its deep system access has led to catastrophic failures, including the deletion of a production database.
