Arindam Mitra

Arindam Mitra studies how language models learn to reason and follow instructions. His early papers address logic puzzles and numerical reasoning, and he earned a computer-science doctorate at Arizona State University in 2019. At Microsoft Research, he led the Orca project and coauthored work on Orca 2 and AgentInstruct. His later work included Orca-Math for grade-school mathematics and Explorer, a multimodal web agent trained with synthesized web trajectories. As of October 2026, he is at Meta.

Timeline

  1. 2015

    A logic-grid puzzle paper

    The village Oodlabari is his home, and he coauthors an EMNLP paper on solving logic-grid puzzles in 2015.

  2. 2019

    A doctorate in reading comprehension

    His computer-science doctorate at Arizona State University, completed in 2019, examines knowledge representation, reasoning, and non-extractive reading comprehension.

  3. 2022

    The NumGLUE benchmark

    He coauthors NumGLUE, an eight-task benchmark for arithmetic reasoning, in 2022.

  4. June 2023–November 2023

    Orca and Orca 2

    In 2023, he coauthors Orca, a 13-billion-parameter model that learns from GPT-4 explanation traces. He also coauthors Orca 2, which uses tailored synthetic data to teach smaller models varied reasoning techniques.

  5. February 2024

    Math with Orca-Math

    In February 2024, he coauthors Orca-Math, a 7-billion-parameter model based on Mistral-7B for grade-school mathematics.

  6. July 2024–November 2024

    Building AgentInstruct

    At Microsoft Research, he leads the Orca project and coauthors AgentInstruct in 2024. The framework uses agentic flows to create prompts and responses from raw documents for language-model post-training.

  7. February 2025

    The Explorer web agent

    In February 2025, he coauthors Explorer, which creates over 94,000 multimodal web trajectories and uses them to train a web agent.

  8. As of October 2026

    At Meta

    As of October 2026, he is at Meta.
