Signal Human-AI teams 73% more productive, but humans still better at image creation

Summary

This signal comes from a 2025 field experiment by MIT and Johns Hopkins involving 2,310 participants. Teams that combined people and AI were 73% more productive than people working alone and also produced better-quality content. There was one important exception, since teams made up only of people still did better at creating images. The researchers read this as a sign that AI agents need more development for visual and multimodal tasks. Even so, EY draws the broader lesson that mixed approaches beat either humans or AI working on their own. It adds that these gains reflect early collaboration models and that the advantage will probably grow as partnerships mature.
