I’ve been using GPT-6 Astra to modernize my React framework and trying out modern Web Platform APIs For example, Explicit Resource Management (DisposableStack, `using`) and composing AbortSignals I also come up with my own StyleX, RSC, streaming integrations, as well as custom build-time stuff that generates icon components and Unicode subsets of webfonts on the fly And yes, almost everything of my site is now optimized using React Compiler The thing about larger models like Astra is that it’s able to handle more complexity, such that I can feed spec and documentation to it to bring the whole site more compliant
