Researchers figured out how to make AI reason more efficiently by having AI figure it out itself. By building an environment where an AI agent writes controller code, tests it, gets feedback, and rewrites it until the strategy gets better. The result cuts token usage by roughly 70% at the same accuracy as running 64 parallel reasoning chains. That's the difference between inference being affordable and inference being a cost problem. The research comes from a team across UMD, UVA, WUSTL, UNC, Google, and Meta. It's called AutoTTS, automated test-time scaling and it's one of the more conceptually interesting papers published this year even if you can't download a model and use it tomorrow.
