The GitHub Projects Transforming How Developers Build AI Systems

The explosion of AI frameworks can overwhelm developers, but only a handful have proven essential for building real-world systems. These seven repositories—spanning LLM orchestration, multi-agent coordination, and retrieval-augmented generation—represent industry standards that help developers move beyond prototype-stage experiments to production-grade applications. Mastering these tools is no longer optional for developers serious about AI; they're the proven building blocks of today's most effective AI systems.
