In the rapidly evolving landscape of artificial intelligence, a French startup called Mistral AI is making waves with its innovative approach to large language models (LLMs).
Founded by a team of expert researchers and engineers from Google, Meta, and Hugging Face, Mistral AI has a mission to democratize access to cutting-edge language technology through open-source models that rival the capabilities of proprietary solutions like GPT-4 and Claude.
The Rise of Mistral 7B
Mistral AI’s journey began with the release of Mistral 7B in September 2023, a 7 billion parameter LLM that quickly attracted attention for its impressive performance despite its relatively small size. Leveraging innovative techniques like Grouped Query Attention (GQA) and Sliding Window Attention (SWA), Mistral 7B achieved state-of-the-art results on various benchmarks, outperforming other models of similar size like LLaMA 7B.
While Mistral 7B cannot compete with much larger models like LLaMA 70B in terms of raw performance, it offers a compelling balance of efficiency and capability. For many applications, Mistral 7B delivers competitive results with a fraction of the computational resources required by massive models.
What sets Mistral 7B apart is not just its performance-to-size ratio, but also its accessibility. The model weights were made freely available under the permissive Apache 2.0 license, allowing researchers and developers to download, modify, and distribute the model for their own purposes. This open-source approach aligns with Mistral AI’s vision of fostering a collaborative community around LLMs, akin to successful open-source movements in web browsers and operating systems.
Introducing Mistral Large and Le Chat
Building on the success of Mistral 7B, Mistral AI has recently unveiled its most advanced model to date: Mistral Large. This proprietary LLM boasts enhanced multilingual capabilities, fluency in English, French, Spanish, German, and Italian, and a generous 32,000 token context window for handling long-form content. Mistral Large also incorporates Retrieval Augmented Generation (RAG) to access external knowledge bases, further improving its comprehension and accuracy.
To showcase the potential of Mistral Large, the company has launched “Le Chat,” an AI chatbot interface similar to ChatGPT. While still in its early stages, Le Chat has already demonstrated competitive performance compared to established rivals like GPT-4 and Claude, albeit with some known weaknesses like outdated information and occasional inaccuracies. Nevertheless, the release of Le Chat marks an important milestone in Mistral AI’s journey to bring open LLMs to the masses.
Partnership with Microsoft
In a significant boost to its efforts, Mistral AI has recently announced a multi-year partnership with Microsoft to make its models available on the Azure AI platform. This collaboration will provide Mistral with access to Microsoft’s vast compute infrastructure for training and deploying its models at scale, while also exposing Mistral’s technology to a broader audience of enterprise customers.
The partnership is a testament to the growing interest in open-source LLMs as a viable alternative to proprietary solutions. By working with Microsoft, Mistral AI aims to accelerate the development and adoption of its models across various sectors, from customer support and content creation to scientific research and beyond.
Comparing Mistral to the Competition
So, how does Mistral stack up against GPT-4, Claude, and Gemini? While direct comparisons are challenging due to differences in model sizes, training data, and evaluation metrics, early results suggest that Mistral is a formidable contender.
On the MMLU benchmark for measuring broad language understanding, Mistral Large achieved the second-highest score among models available via API, behind only GPT-4. It has also demonstrated strong performance on coding and math tasks, often outperforming larger models like LLaMA 70B.
However, Mistral’s true strength lies in its efficiency and convenience. The Mistral 7B model, for instance, offers performance comparable to Code-LLaMA 7B on programming tasks while maintaining superior results on non-coding benchmarks. This versatility makes Mistral an attractive option for developers and businesses looking to leverage LLMs without breaking the bank.
The Ex Machina AI.Lab’s Experiments with Mistral
The AI.Lab has conducted various experiments with Mistral models, leveraging its unique strengths. In particular, Mistral’s proximity to European languages makes it an ideal choice for multilingual applications. Mistral’s open-source license also allows the AI Lab to modify and adapt the model to its specific needs.
Another key advantage of Mistral is its support for function calling, albeit currently incomplete. This functionality opens the door to integrating Mistral with external systems and extending its capabilities beyond simple text completion. The AI.Lab is exploring ways to leverage Mistral’s function calling to create more powerful and flexible solutions.
Looking ahead, the AI.Lab recognizes that the LLM landscape is rapidly evolving, and new options will likely emerge. For this reason, the AI.Lab is taking an agnostic approach in developing its Mistral-based solutions, allowing for an easy transition to other LLMs if needed without having to redo everything from scratch.
The Road Ahead
As impressive as Mistral’s results have been so far, the company is only just beginning. With $113 million in initial funding and a growing team of top AI talents, Mistral AI has set its sights on developing even more powerful models in the coming years, with the ambitious goal of surpassing GPT-4 by 2024.
Beyond scaling its models, Mistral AI is also exploring new architectures and training techniques to further improve efficiency and performance. The recently introduced Mixtral 8x7B, for example, employs a sparse mixture-of-experts approach to achieve competitive results with a fraction of the parameters of dense models. This focus on architectural innovation positions Mistral at the forefront of the open LLM movement.
Challenges remain, of course. As Mistral’s models become more widely used, issues of bias, misinformation, and potential misuse will need to be addressed. The company has emphasized its commitment to responsible AI development, but navigating the ethical implications of powerful language models is an ongoing process that will require input from diverse stakeholders.
In a short time, Mistral AI has emerged as a major player in the world of open-source language models. Combining cutting-edge research with a community-driven approach, the company is democratizing access to LLM technology and challenging the dominance of proprietary solutions.
As Mistral continues to refine its models and expand its partnerships, the potential applications are vast. From enhancing customer experiences to accelerating scientific discoveries, LLMs like Mistral have the power to transform industries and shape the future of AI. And with its open-source ethos and commitment to innovation, Mistral AI is well-positioned to lead the charge.
The AI.Lab’s experiments with Mistral demonstrate the potential of this powerful open-source LLM. By leveraging Mistral’s strengths, such as its proximity to European languages, flexible licensing, and support for function calling, the AI.Lab is developing solutions that can adapt to the evolving LLM landscape.
