Google's AI Programming Intelligence Jules in Global Beta, Challenges GitHub Copilot and OpenAI's Codex

On May 20, Google's AI programming intelligence Jules entered a new phase of development, and after a private preview in December 2024, a global public beta was launched, making the AI tool available to any developer with a Google account. Jules isn't simply an auto-completion tool for code, it launches a disposable virtual machine (Cloud VM) in the cloud, clones the target Jules is not a simple code-completion tool. It starts a one-time virtual machine (Cloud VM) in the cloud, clones the target codebase, and creates a detailed multi-step program before starting to modify files. Google says Jules runs on the Gemini 2.5 Pro multimodal model, which analyzes large file structures and project histories while following codebase-specific contribution guidelines, directly challenging GitHub Copilot and OpenAI's Codex.
