Harvard & MIT Create 8.3B Virtual Humans Using LLMs for Instant Market Research
mtizard · x · 2026-08-11
Harvard and MIT have introduced MatrAIx, a digital twin project creating 8.3 billion virtual humans equivalent to the global population.
- Each virtual human possesses 1,290 distinct attributes, including age, psychology, spending habits, and price sensitivity.
- By plugging these profiles into LLMs like GPT and Claude, they achieved 91.5% personality consistency in tests, reacting like real humans in surveys and web interactions.
- This approach could compress traditional market research and focus groups into an overnight process on a single server, drastically transforming product development and marketing.
