Copilot can modernize apps, such as upgrading Java 8 to Java 21 or .NET 6 to .NET 9, and migrate on-premises apps to the cloud. - Autonomous SRE Agent: Introduced an SRE (Site Reliability Engineering) agent capable of automatically categorizing live site issues like memory leaks, identifying root causes, mitigating problems, and recording incident management reports in GitHub Issues. - Full Coding Agent within GitHub: Announced a complete coding agent within GitHub that elevates Copilot from a pair programmer to a peer programmer, autonomously handling tasks like bug fixes, adding new features, and maintaining code. This feature is now available to all users. CEO Nadella demonstrated assigning a bug from GitHub Issues to Copilot. - Agent security and ecosystem: Agents operate within their own branches, use only developer-configured MCP servers, and allow other agents to perform code reviews to ensure security. Features to build diverse agent ecosystems, such as SRE, SUI, and code review agents, are also available to partners. ❇️ Collaboration with OpenAI: Codex Agents and the Future of AI Models OpenAI CEO Sam Altman participated virtually to discuss the vision for coding agents and the roadmap for AI models. - Vision for Codex Agents: Explained the evolution of agents into true virtual team members capable of task delegation, bug fixing, and implementing new features, emphasizing genuine software engineering task delegation. - AI Model Roadmap: Predicted that models will become smarter, easier to use, more reliable, and enhanced with features like multimodality, tool usage, and integration. - Advice for building agent apps: Recommended preparing for the rapid pace of model performance changes and actively adopting new tools and workflows.
