Timeline

  1. June 2025

    Magistral reasoning model

    In June 2025, he coauthors Magistral, Mistral's first reasoning model; the paper presents a scalable reinforcement-learning pipeline for training language models.

  2. July 2025

    Voxtral audio chat models

    Voxtral is the subject of a July 2025 paper he coauthors; it presents Voxtral Mini and Voxtral Small as multimodal audio chat models for spoken audio and text documents.

  3. 2025

    Devstral-Small for code agents

    He coauthors a 2025 technical report introducing Devstral-Small, an open-source model for code agents.

  4. July 2026

    Robostral Navigate

    Robostral Navigate is an 8B vision-language model he coauthors in July 2026, built to predict waypoints from monocular RGB images.

  5. July 2026

    Shieldstral safety classifier

    Shieldstral is a 3B-parameter policy-adaptive multimodal safety classifier he coauthors in July 2026; it frames content moderation as a binary question-answering task.

  6. As of October 2026

    HPC Lead at Mistral

    As of October 2026, he is HPC Lead at Mistral AI. In March 2026, he joins software architect Jean-Olivier Gerphagnon for a GTC session on creating Mistral Compute.

  1. Google had the most people shaping AI every year from 2014 to 2025Our estimates of which organizations employed the most people shaping AI from 1961 to 2025, with a year-by-year chart.
  2. The United States employs an estimated 53% of people in our data with a known employment countryOur estimates of where AI careers are concentrated now and how countries’ shares of dated positions changed over time.
  3. 46% of living people in our data with known birth and employment countries work outside their birth countryOur estimate of cross-border careers in AI, from country of birth and the country of each current organization.
  4. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionOur estimates of where the people shaping AI studied and where their careers led, from education records in cited biographies.
