LLMs in the Trenches - Boosting C++ System Programming with AI

Explore how Large Language Models are revolutionizing C++ systems programming in this conference talk from CppCon 2025. Discover practical applications of LLMs in real-world C++ development, including performance tuning, low-level debugging, refactoring, and code generation across both Linux and Windows platforms. Learn from hands-on experience building performance-critical software as the speaker demonstrates workflows that effectively integrate LLMs with human expertise to achieve meaningful productivity gains. Understand how to avoid common pitfalls and hallucination traps while leveraging AI tools for systems programming. Gain practical techniques and insights into model behavior, along with an honest evaluation of where LLMs excel and where human intuition remains essential. The presentation includes live demonstrations and real-world project examples, providing attendees with actionable knowledge for incorporating AI assistance into their C++ development workflow.
