Agentic coding assistants have transformed the way we build software – and they can be even more impactful for AI development itself. So what if we could take some of the learnings from AI-powered coding assistants and apply them to building our own custom AI systems that are better, faster and fully under our control? In this talk, I'll show you these new agentic development workflows, what they mean for developer tools and why code and the open-source ecosystem are more important than ever.
