OpenAI 谈 computer use 一年提速 10 倍
OpenAI 的 Thibault Sottiaux 拆解 computer use 一年提速 10 倍的原因：不只是模型采样更快，还改进了 harness、思考步长，并加入 AutoReview（内部称 Guardian）监督主 agent。
OpenAI made computer use 10x faster in a year. @thsottiaux breaks down what changed under the hood: “It’s not that we made the model sample faster. It’s both the harness and the model.” “How much does it need to think before it can take the next action reliably? That’s one element that we really improved.” “We have a second agent, which we call AutoReview, or internally we call it Guardian, which watches over the primary agent.” “So we also made this AutoReview model faster.” “We were able to use Astra at scale in order to improve the performance of the harness, do more things in parallel, remove little stalls.” “Combine all of this together, and then we got this 10x speedup.”
