In a bold move that signals its intent to compete with the biggest names in the AI industry, French startup Mistral AI has unveiled its first multimodal AI model, Pixtral 12B. This new entrant aims to shake up the image processing domain, taking on industry titans like OpenAI and Anthropic.
A Strategic Leap Forward
Established less than two years ago, Mistral AI has quickly made a name for itself with the launch of Pixtral 12B. The model’s introduction, supported by substantial backing from the European Union, underscores the company’s ambition to lead in technological innovation and reflects the broader trend of the AI sector moving towards multimodal capabilities.
A Rising Star in AI
Leading the charge is Arthur Mensch, the co-founder and CEO of Mistral AI, who has recently been honored as one of the 35 Innovators Under 35 by MIT Technology Review for 2024. Under his stewardship, the young company, with a team of just 65, is daring to challenge well-resourced tech giants.
A Multimodal Breakthrough
Pixtral 12B represents Mistral AI’s first attempt to merge visual processing with natural language processing. Building upon the company’s previously released text model Nemo 12B, Pixtral 12B incorporates a visual adapter with 400 million parameters, enabling dual processing of images and text.
The model boasts a total of 12 billion parameters spread across 40 layers, with 14336 hidden dimensions and 32 attention heads, providing robust support for complex computational tasks. Its visual encoder supports image processing at a resolution of 1024×1024 pixels and features 24 hidden layers.
Innovative Features
One of the model’s standout features is its flexible image processing capability. Pixtral 12B uses a 16×16 pixel block processing method, which allows it to effectively handle high-resolution images. Additionally, the model incorporates 2D Rotary Position Embedding (RoPE) technology, enhancing its ability to understand spatial relationships within images.
Users can input images into Pixtral 12B via URLs or base64 encoding, combining them with text prompts to analyze image content. This versatility enables the model to perform a variety of tasks, including image classification, object counting, and generating image descriptions. To support these functions, the model introduces three special tokens: img, imgbreak, and imgend.
A Different Approach to Release
Mistral AI took an unconventional route to release Pixtral 12B, initially providing seed links for downloading the model files, which are approximately 24GB in size. Subsequently, the source code was made public on GitHub and the AI distribution platform Hugging Face.
While the model is not yet directly accessible online, developers can download the source code to test and use it in their personal environments. Sophia Yang, the head of developer relations at Mistral AI, stated on social media that the company will soon provide an interface for Pixtral 12B through its network chatbot, allowing potential developers to experience the new model.
Future Prospects and Licensing
The company has yet to clarify the licensing terms for Pixtral 12B. Previous models released by Mistral AI have been under the Apache 2.0 open-source license, but it remains to be seen if Pixtral 12B will follow suit. Industry speculation suggests that the model may be freely available for research and academic purposes, while commercial applications will require a paid license.
Challenging the Status Quo
Pixtral 12B’s flexible image processing capabilities make it suitable for a wide range of complex scenarios, from simple image description tasks to sophisticated visual question-answering systems. The model’s text capacity has been expanded to 131072 tokens, providing a broader range of language understanding and generation abilities.
Combined with its powerful visual processing, Pixtral 12B is poised to play a significant role in areas such as content analysis, data visualization, and image retrieval. Although Mistral AI has not yet disclosed the training dataset and detailed performance metrics of Pixtral 12B, the industry widely believes that this model will bring new possibilities to the development of visual applications and data analysis.
A Growing Presence in AI
Since its inception, Mistral AI has not only established a strong pipeline of model development but has also forged partnerships with industry giants like Microsoft and Amazon to expand its technological influence. The company recently raised $640 million in funding at a valuation of $6 billion, providing a solid financial foundation for its ongoing innovation and market expansion.
Following the funding round, Mistral AI launched Mistral Large 2, a model with advanced multilingual capabilities that rivals GPT-4 in reasoning, code generation, and mathematical calculations. Alongside Pixtral 12B and Mistral Large 2, the company has released several other specialized
