What is Mistral API?

Mistral AI provides a range of large language models developed in Europe, available through both open-source and proprietary APIs. The company offers models of varying sizes and capabilities, from smaller efficient models suitable for local deployment to larger frontier models for complex tasks. You can access these models via API, integrate them into applications, or use the open-source versions for self-hosted deployments. Mistral caters to developers, researchers, and organisations seeking alternatives to US-based model providers, with an emphasis on accessibility and flexibility in how models are deployed and used.
