受抵制运动影响，大量用户开始转向被认为更具“道德底线”的竞争对手Anthropic。2月28日，在OpenAI宣布与美国国防部合作当天，ChatGPT移动端单日卸载量激增295%，应用商店一星评价暴增775%，五星好评则腰斩了50%。与此同时，Claude在美国的下载量首次超越ChatGPT，登顶苹果应用商店免费榜榜首。
We present lf-lean, a verified translation of all 1,276 statements of the Logical Foundations textbook from Rocq to Lean, produced by frontier AI with ~2 person-days of human effort versus an estimated ~2.75 person-years manually (a 350x speed-up). We achieve this through task-level specification generators: because many software transformations are semantics-preserving, correctness can be defined once for an entire task class and checked automatically across all instances and codebases. This scales human oversight from 𝒪(𝓃) to 𝒪(1) regardless of program complexity. Placed on METR’s time horizon graph, our result suggests verified software engineering is advancing faster than expected.

We have several types with progressively less information. This is useful, as you can choose the type you want to represent and don't need to worry about running calculations on any other un-needed data (such as calculating the time if you're only interested in displaying the date).
