Khyathi Raghavi Chandu
Also known as Khyathi Chandu
Khyathi Raghavi Chandu is an AI research scientist at Mistral AI, where she works on the Voxtral audio models and the Magistral reasoning models. Trained in computer science at IIIT Hyderabad from 2011, she earned a PhD in 2021 at Carnegie Mellon University's Language Technologies Institute with a focus on grounded multimodal long-form generation. After two years as a research scientist at Meta AI, she joined the Mosaic team at the Allen Institute for AI in 2023 and co-authored the OLMo language model and the Dolma corpus, which both won best paper awards at ACL 2024. At Mistral, she co-authored Magistral, the company's first reasoning model, in 2025 and the Voxtral TTS speech model in 2026.

2011–2016
Dual degree at IIIT Hyderabad
She joins IIIT Hyderabad in 2011 to study computer science and works with Prof. Dipti Misra Sharma in her first year; an S.N. Bose Scholarship takes her to the University of Pennsylvania for a summer as a research intern. By 2016, she completes a dual bachelor's and master's degree there, with a thesis on code-mixed question answering for Indian languages.
