GitHub Copilot now has a better AI model and new capabilities

GitHub Copilot has undergone significant updates to enhance the quality, responsiveness, and security of its code suggestions. The underlying Codex model has been upgraded, leading to a notable increase in the percentage of code generated by Copilot, with Java developers seeing up to 61% of their code being produced by the tool. These improvements include a new Fill-In-the-Middle (FIM) paradigm for better context understanding and a lightweight client-side model that reduces unwanted suggestions. Additionally, an AI-based vulnerability prevention system has been introduced to block insecure coding patterns in real-time, targeting issues like hardcoded credentials and SQL injections. These enhancements aim to help developers code more efficiently and securely, with GitHub Copilot now offering an improved experience for both individuals and businesses.
