Lab leader

Jiahui Yu

Jiahui Yu is an AI researcher and lab leader whose work spans computer vision, image generation, and multimodal systems. His early papers introduced object-detection and image-inpainting methods; later work included VQGAN and the Parti text-to-image model. At Google DeepMind, he co-led Gemini’s multimodal work; at OpenAI, he coauthored the GPT-4o System Card and led multimodal training for o3 and o4-mini. Meta hired him in 2025 for its Superintelligence group, where he led work on Muse Spark; as of October 2026, he is starting a new company.

Timeline

  1. 2016–2018

    Object detection and image inpainting

    In 2016, he coauthors UnitBox, which uses an intersection-over-union loss to predict object bounding boxes. In 2018, he coauthors a gated-convolution system for completing images with free-form masks.

  2. 2021–2022

    Image models with discrete tokens

    In 2021, he coauthors work on improved Vision-Transformer-based VQGAN, which encodes images as discrete tokens for autoregressive modeling. In 2022, he coauthors Parti, an autoregressive text-to-image model that generates high-fidelity images and supports content-rich synthesis involving complex compositions and world knowledge.

  3. 2023

    Co-leading Gemini multimodal work

    At Google DeepMind, he co-leads Gemini’s multimodal pillar in 2023. The Gemini report describes image, audio, video, and text understanding across the model family.

  4. 2024

    Contributing to GPT-4o

    In 2024, he coauthors OpenAI’s GPT-4o System Card, which covers the model’s capabilities, limitations, and safety evaluations.

  5. 2025

    Training o3 and o4-mini

    In 2025, he leads multimodal post-training for o3 and serves as the directly responsible individual for o4-mini from pretraining through post-training. He leads OpenAI’s Perception team.

  6. June 2025

    Moving to Meta Superintelligence

    Meta hires him from OpenAI for its Superintelligence group in June 2025.

  7. 2026

    Muse Spark multimodal work

    At Meta, he serves as multimodal pod lead for Muse Spark in 2026.

  8. As of October 2026

    Starting a new company

    As of October 2026, he is starting a new company after co-founding TBD Lab within Meta Superintelligence Labs.
