Mistral

Mistral is a French AI company producing high-quality open-weight models. Mistral Large competes with GPT-4 and Claude on reasoning and complex tasks. Mistral Small is optimized for low-latency applications where speed matters more than peak capability. Codestral is their code-specialized model with fill-in-the-middle support for autocomplete. All models have strong multilingual performance, particularly for European languages. Mistral pioneered the sliding window attention and mixture-of-experts techniques that are now industry standard. You can access models through their API (La Plateforme), download open weights for self-hosting, or use them via OpenRouter and other gateways. For European companies with data sovereignty requirements, Mistral is the natural choice.
