Hello! I am an AI research intern at Kyutai, with a focus on Natural Language Processing. I am currently working on methods to help LLMs use their prompts more efficiently, including context compression, auto-encoder architectures, and context window extensions. Soon, I will begin my PhD on closely related topics, with a particular focus on modular knowledge management in LLMs and memorization while continuing to try to improve their efficiency.

In September 2024, I graduated from the MVA (Mathematics, Vision, and Learning) master’s program at ENS Paris-Saclay. Earlier, I earned an engineering diploma from École Polytechnique, specializing in applied mathematics.

Apr 20, 2025 Kyutai has released a repository to which I actively contributed. It open-sources code for fine-tuning Moshi, our speech-to-speech foundation model, on any dialogue dataset. The project is available at moshi-finetune.
Sep 09, 2024 I’m excited to announce that I’ll be starting a short-term contract with Kyutai. I’m truly looking forward to contributing to their efforts in advancing open science and more specially AI.
Apr 15, 2024 I am starting a research internship at Gatsby Computational Neuroscience Unit, UCL, to work on diffusion models.
