## Mistral AI: A European Challenger

Mistral AI was founded in April 2023 by former researchers from [Google DeepMind](https://www.wikiprompt.org/wiki/google-deepmind) and Meta Platforms. The company quickly gained attention for its open-weight models, which were designed to compete with proprietary systems from American firms. Mistral's first model, Mistral 7B, was released in September 2023 and received positive reviews for its performance relative to its size. The company subsequently released larger models, including Mistral 8x7B and Mistral Large, the latter being the flagship model offered through the Microsoft partnership.

Mistral AI's approach emphasized efficiency and transparency, with models available under open licenses for certain use cases. This contrasted with the more closed strategies of competitors like OpenAI and [Anthropic](https://www.wikiprompt.org/wiki/anthropic). The company's European base also made it an attractive partner for Microsoft, which sought to navigate regulatory environments in the European Union, particularly regarding data privacy and AI governance.

## The Partnership Agreement

The partnership between Microsoft and Mistral AI, announced on February 26, 2024, included several components. Microsoft invested $16 million in Mistral AI, a relatively small amount compared to its investments in other AI companies, but significant for a startup of Mistral's size. The agreement also included a multi-year collaboration to integrate Mistral's models into Azure, making them available to Azure customers through the Azure AI Studio and the Azure Machine Learning platform.

Under the terms of the deal, Mistral AI's models, including Mistral Large, would be hosted on Azure infrastructure, providing customers with access to European-developed AI technology. The partnership also involved joint research and development efforts, with Microsoft and Mistral AI working together on model optimization and deployment. Microsoft committed to supporting Mistral AI's growth by providing technical expertise and access to its global cloud network.

The investment was structured as part of a larger funding round for Mistral AI, which had previously raised €105 million in a seed round led by Lightspeed Venture Partners in June 2023. The Microsoft investment brought Mistral AI's total funding to over $400 million, valuing the company at approximately $2 billion.

## Strategic Implications

The Microsoft-Mistral AI partnership had several strategic implications for the AI industry. For Microsoft, the deal provided access to a European AI developer with strong technical capabilities, allowing the company to offer a more diverse range of models on Azure. This diversification was seen as a hedge against over-reliance on OpenAI, which had become Microsoft's primary AI partner.
