Von Ahn's April 2025 'AI-first' memo made AI use part of hiring and performance reviews. In April 2026 he said Duolingo had backtracked on the review metric: 'if it can't [help], I'm not going to force you to do that.' The policy changed, so the mandate is now unclear.[1][2][3][4]

- Von Ahn said in April 2026 that AI is 'not yet' better at coding than humans and that AI-written code can be hard to debug. A spokesperson said AI tools assist work but 'don't make decisions'.[4]
