Mistral AI has announced the early access release of its first AI endpoints, including three chat endpoints and an embedding endpoint. The endpoints have different performance and price tradeoffs, with the highest-quality endpoint serving a prototype model that outperforms ChatGPT 3.5. The models are open-sourced and can be downloaded, and the API follows the specifications of a popular chat interface. The company is progressively ramping up its capacity and offers a Python and Javascript client library to query its endpoints.
