Baptiste Bout

Baptiste Bout’s published research with Mistral AI covered multimodal language models, reasoning, and speech through April 2026. He joined the iGEM Evry Paris-Saclay team from École Polytechnique in 2023 and coauthored Pixtral 12B, a 12-billion-parameter multimodal language model, in 2024. His 2025 work included Magistral, Mistral AI’s first reasoning model, and the Voxtral Mini and Small multimodal audio chat models. In 2026, he coauthored Voxtral Realtime for streaming speech recognition and Voxtral TTS for multilingual speech generation.
