Maty Bohacek

I am a researcher at Stanford University working with Prof. Maneesh Agrawala. I work at the intersection of AI and media integrity. In a world that is becoming increasingly AI-mediated, my goal is to build AI systems and networks that are inherently trustworthy and interpretable, resulting in productive, democratic discourse.

The Impact of AI-Generated Text on the Internet

Jonas Dolezal, Sawood Alam, Mark Graham, Maty Bohacek

Measures the prevalence of AI-generated text on the web and finds reduced semantic diversity and increased positive sentiment, but no statistical support for decreased factual accuracy or stylistic homogenization.

Snippets of My Work

  • Working with Maneesh Agrawala.
  • We built methods to understand what concepts cannot be generated by image models, enable artists to better understand and interface with AI systems, and more.
  • Currently exploring concept erasure, model weight distances, and more.
  • Working with Sergey Sanovich
  • We are studying the impact of AI content on the information commons.
  • Worked with Thomas Leung, Nick Dufour, Stephanie CY Chan, Nino Scherrer, Roma Patel, Rishub Jain, and others.
  • We built a method to understand competency gaps of language models and their benchmarks and found that cascading linear features in language models help detect and control sycophancy.
  • Worked with the Labs team.
  • We built a membership inference method for image models and a method for detecting AI-generated motion in video.
  • Worked with Evan Ratliff, Samantha Henig, and Sophie Bridges to create a podcast about AI agents and work.
  • Ranked among best of 2025 by the New York Magazine, The Economist, The Information, and a finalist in the iHeart Podcast Awards and The Ambies.
  • Worked with Sarah Barrington and Hany Farid to create DeepSpeak, a dataset and benchmark for deepfake detection. Open-source and licensed to 100+ academic institutions.
  • More versions coming.
