Their decision to strike out on their own stemmed from a desire to build more efficient, accessible, and transparent AI systems, with a particular emphasis on addressing the specific needs and values of the European market.
The company’s core mission revolves around developing and deploying cutting-edge AI models while championing open-source principles and ethical considerations. This approach contrasts with the more closed and proprietary models often favored by larger tech companies, aiming instead to foster collaboration and innovation within the AI community. Mistral AI believes that open-source models can democratize access to advanced AI capabilities, enabling a wider range of developers and researchers to build upon and improve these technologies.
Flagship Models and Technical Innovations:
Mistral AI has quickly released several impressive models, each demonstrating significant advancements in performance and efficiency. Their flagship models are characterized by their open weights, permissive licensing, and ability to perform exceptionally well across a variety of benchmarks.
-
Mistral 7B: This initial offering garnered considerable attention for its impressive performance relative to its size. Despite having only 7 billion parameters, Mistral 7B surpassed the performance of many larger models, including Llama 2 13B, in a variety of tasks. This was achieved through architectural innovations, particularly the use of grouped-query attention and sliding window attention. Grouped-query attention reduces computational costs by allowing multiple query heads to share the same key and value heads, while sliding window attention restricts attention to a limited context window, further improving efficiency and enabling longer context processing. The 7B model is particularly adept at code generation, reasoning, and text understanding.
-
Mistral 8x7B: Building upon the success of the 7B model, Mistral AI introduced Mixtral 8x7B, a sparse mixture-of-experts (MoE) model. This architecture consists of eight expert models, each with 7 billion parameters, but during inference, only two experts are activated for each token. This results in significantly increased capacity and improved performance while maintaining computational efficiency. The MoE architecture allows the model to specialize in different areas of knowledge, leading to better performance across a wider range of tasks. Mixtral 8x7B excels in areas such as multilingual text generation, mathematical reasoning, and creative writing. Its open-source nature has enabled researchers and developers to fine-tune and adapt the model for specific applications.
-
Mistral Large: Positioned as a direct competitor to models like GPT-4 and Claude 3, Mistral Large represents the pinnacle of Mistral AI’s current offerings. This closed-source model boasts exceptional performance across a wide range of benchmarks, demonstrating state-of-the-art capabilities in areas such as reasoning, knowledge retrieval, and code generation. While not open-source, Mistral Large is available through the Mistral AI platform, providing access to its advanced capabilities through an API.
Architectural Innovations:
Beyond the specific models, Mistral AI’s success is driven by its innovative approach to model architecture and training. They have focused on developing models that are both powerful and efficient, leveraging techniques such as:
-
Grouped-Query Attention (GQA): Reduces the computational cost of attention mechanisms by sharing key and value heads across multiple query heads. This improves inference speed and reduces memory requirements.
-
Sliding Window Attention (SWA): Limits the attention window to a fixed size, allowing the model to process longer sequences more efficiently. This is particularly useful for tasks that require understanding context over a large span of text.
-
Mixture-of-Experts (MoE): Utilizes multiple expert models, each specializing in different areas of knowledge. During inference, only a subset of experts are activated, resulting in improved performance and efficiency.
