philipkiely · x · 2026-08-08
As model capabilities evolve rapidly, the abstraction layers used to build AI applications must also change. The article "Against agent sprawl" explores the future of AI engineering toolchains in an era where models are never shipped in isolation and no single model is the clear best choice.
Engineers used to argue about which model to choose, but the focus has now shifted to "harness-model fit." The piece offers a compelling vision for solving "agent sprawl" and outlines what the next layer of AI tooling should look like.
