Researcher

Kyle Lo

Kyle Lo is an AI researcher whose work spans scientific text, open language models, and vision-language systems. He coauthored SciBERT in 2019, S2ORC in 2020, and Dolma in 2024; Dolma won ACL's Best Resource Paper Award. DrawEduMath appeared among NAACL's 2025 Outstanding Papers, and Molmo and PixMo received CVPR's 2025 Best Paper Honorable Mention. He coauthored OpenScholar in 2026 and worked as a research scientist at Ai2 while co-leading OLMo until March 2026. As of October 2026, his research focuses on large-scale language-model pretraining, data curation, data mixing, benchmark validity, efficient experimentation, and generalization across model scales.

Timeline

  1. 2019

    SciBERT for scientific text

    He coauthors SciBERT in 2019, a BERT-based model pretrained on scientific publications to improve downstream scientific NLP tasks.

  2. 2020

    S2ORC for academic papers

    In 2020, he coauthors S2ORC, a corpus of 81.1 million academic papers with structured full text for 8.1 million open-access papers. The corpus supports research and tools for mining academic text.

  3. 2024

    Dolma and an ACL award

    Dolma is the three-trillion-token English corpus he coauthors in 2024 for language-model pretraining. The paper wins ACL's Best Resource Paper Award.

  4. April 2025

    DrawEduMath student math images

    In April 2025, he coauthors DrawEduMath, an English-language dataset of 2,030 images of students’ handwritten responses to K-12 math problems. The team evaluates vision-language models on teacher-written questions and synthetic questions derived from teacher descriptions, and the paper appears among NAACL's Outstanding Papers.

  5. June 2025

    Molmo and PixMo at CVPR

    In June 2025, CVPR recognizes Molmo and PixMo, the vision-language work he coauthors, with a Best Paper Honorable Mention. Molmo is an open family of models with PixMo datasets for image captions, image questions, and pointing.

  6. February 2026

    OpenScholar for literature search

    In February 2026, he coauthors OpenScholar, a retrieval-augmented language model that answers scientific queries using relevant passages from 45 million open-access papers and produces citation-backed responses. The team introduces ScholarQABench, a multi-domain benchmark for scientific literature search.

  7. March 2026

    Leaving Ai2

    Until March 2026, he works as a research scientist at the Allen Institute for AI and co-leads OLMo, its open language-modeling project. He says farewell to Ai2 in March 2026.

  8. As of October 2026

    Language-model pretraining research

    As of October 2026, he is an AI researcher focused on large-scale pretraining of language models, with emphasis on data curation, data mixing, benchmark validity, efficient experimentation, and generalization across model scales.
