Mistral AI
FeaturedFrontier AI in your hands.
Founded in 2023 by Arthur Mensch, Guillaume Lample, and Timothée Lacroix in Paris, Mistral AI was created by three former researchers from DeepMind and Meta AI who believed powerful AI should be open and not concentrated in the hands of a few US companies. Their first model, Mistral 7B, released in September 2023, outperformed much larger models and made waves across the AI community. Mistral raised a record-breaking €600 million Series B in 2024 at a €6 billion valuation, becoming Europe's leading AI startup. Its Le Chat assistant and API compete directly with OpenAI and Anthropic.
