Career

Kim worked as a software engineer at NCSOFT and then as a recommender system engineer and data scientist at Kakao, building distributed systems and Spark applications for recommendations. Kim later held research internships at Pandora in 2017 and Spotify in 2018.82

Kim joined OpenAI as a member of technical staff in August 2019. Kim's résumé describes developing and open-sourcing multimodal models such as Jukebox, CLIP and Whisper, building the Whisper API, and taking part in data engineering for GPT-4 with vision.82

Research

Kim's early research was in music information retrieval, including CREPE (2018), a convolutional model for pitch estimation. At OpenAI, Kim co-authored Jukebox (2020), a generative model for music.9810

Kim is second author of the CLIP paper (2021), which trains image and text encoders together from natural language supervision, and of the Whisper paper (2022), on speech recognition trained with large-scale weak supervision. In the Whisper repository, Kim announced large-v3 in 2023, which uses 128 Mel frequency bins, and large-v3-turbo in 2024, which reduces the decoder to 4 layers.3456

Work and contributions

  • CLIP ViT-L/14 Open weights

    Second author, after Alec Radford, of the 2021 paper "Learning Transferable Visual Models From Natural Language Supervision", which introduced CLIP.38

  • Whisper large-v3 Open weights

    Second author of the Whisper paper, and posted the November 2023 announcement of the large-v3 model in the openai/whisper repository as a maintainer.45
