Researcher

Valeriia Nemychnikova

Valeriia Nemychnikova is an AI researcher whose work spans reasoning, language models, coding agents and speech. They coauthored 2025 papers on reinforcement-learning reasoning, multimodal audio chat and code agents. In January 2026, they coauthored the Ministral 3 report on dense models for compute- and memory-constrained applications. In February 2026, they coauthored Voxtral Realtime; in March 2026, they coauthored Voxtral TTS, which native-speaker evaluations prefer for multilingual voice cloning, with a 68.4% win rate over ElevenLabs Flash v2.5. As of October 2026, they are affiliated with Poolside AI.

Timeline

  1. June 2025

    Magistral reasoning models

    In June 2025, they coauthor Magistral, Mistral's first reasoning model and its reinforcement-learning pipeline. The paper presents Magistral Medium, trained for reasoning with RL alone, and open-source Magistral Small.

  2. July 2025

    Voxtral audio chat

    In July 2025, they coauthor Voxtral, which presents Voxtral Mini and Voxtral Small as multimodal audio chat models that comprehend spoken audio and text documents.

  3. August 2025

    Devstral for code agents

    In August 2025, they coauthor the Devstral report, which introduces Devstral-Small as a lightweight open-source model for code agents.

  4. January 2026

    Ministral 3 models

    In January 2026, they coauthor the Ministral 3 report, which describes parameter-efficient dense language models in 3B, 8B and 14B sizes for compute- and memory-constrained applications.

  5. February 2026

    Streaming speech recognition

    In February 2026, they coauthor Voxtral Realtime, a natively streaming automatic speech-recognition model that matches offline transcription quality at sub-second latency.

  6. March 2026

    Multilingual speech generation

    In March 2026, they coauthor Voxtral TTS, an expressive multilingual text-to-speech model. Native-speaker evaluations prefer it for multilingual voice cloning, with a 68.4% win rate over ElevenLabs Flash v2.5.

  7. As of October 2026

    Poolside AI affiliation

    As of October 2026, they are affiliated with Poolside AI.
