Kairos beats Persimmon, Astra, Fable, and Gemini across 13 simulation benchmarks

Kairos 1, announced by Kevin Bang He, is described as the first model built to simulate individual human behavior and outperforms Persimmon, Astra, Fable, and Gemini across 13 simulation benchmarks, according to the announcement. The benchmark results come from an early training checkpoint, and the team says it is continuing to scale Kairos. The announcement argues frontier models only capture population averages, while Kairos targets individual differences shaped by context and personality.

Pre-training on the internet has given models superhuman IQ but no sense of how people actually make decisions. Surveys, traces, and scraped data do not provide enough fidelity to accurately replicate human decisions, which are informed by context, personality, and personalShow more

Our mission is to unlock universal understanding of humanity through one model of human behavior. The benchmark results come from an early training checkpoint, and we are continuing to scale Kairos. We're hiring!
