π° What Happened
San Francisco startup Mirror Particle is building a "world model" of human behavior. It gives brands an AI engine that predicts what consumers will do and why.
CEO Abhivyakti Ahuja says the common method, using language models to role-play as a group, is broken. She says those models only study written words, not how humans really see and act.
π The Backstory
Startups that predict human behavior are getting a lot of money right now. Simile raised $200 million, Aaru raised $88 million, and Humans raised $480 million. Most rely on large language models.
Mirror Particle wants to build its model from scratch to better simulate human choices. The goal is to understand not just what people do, but why they do it.
π― Why It Matters
Better behavior prediction could shape the ads, prices, and products you see. It raises questions about privacy and influence.
