Discover Today, we release our new conversational assistant, le Chat Mistral, a first demonstration of what you can build with Mistral models and what you can deploy in your business environment. A multilingual conversational assistant based on Mistral models Le Chat is a conversational entry point to interact with the various models from Mistral AI. It offers a pedagogical and fun way to explore Mistral AI’s technology. Le Chat can use Mistral Large or Mistral Small under the hood, or a prototype model called Mistral Next, designed to be brief and concise. We are hard at work to make our models as useful and as little opinionated as possible, although much remain to be improved!
