What Is Sakana AI


Sakana AI, a startup founded by former Google researchers, is taking a bold and innovative approach inspired by the very essence of nature itself. By harnessing evolutionary algorithms and model merging techniques, this pioneering company is creating AI models that are not only powerful but also adaptable, efficient, and cost-effective.

What is Sakana AI?

Sakana AI is a Tokyo-based artificial intelligence startup founded by David Ha and Llion Jones, both former Google researchers with an impressive track record in AI innovation. The company’s mission is to establish Tokyo as a prominent center for AI innovation, much like how OpenAI has positioned San Francisco and DeepMind has positioned London.

The startup’s founders recognized that the natural world has been perfecting its systems through an evolutionary process that spans billions of years. By mimicking these natural principles, Sakana AI aims to create AI models that are not only powerful but also capable of adapting and evolving to meet ever-changing demands.

Features of Sakana AI

  • Model Merging: This groundbreaking technique involves combining multiple AI models to create more powerful and adaptable systems. By leveraging model merging, Sakana AI has developed high-performance Japanese Large Language Models (LLMs) and Vision-Language Models (VLMs).
  • Evolutionary Algorithms: Sakana AI employs evolutionary principles to automatically select and merge the best models, mimicking the process of natural selection. This approach allows for the creation of sophisticated AI systems more efficiently and cost-effectively.
  • Swarm Intelligence: Inspired by the collective behavior of schools of fish and beehives, Sakana AI develops numerous smaller AI models that work together to achieve complex tasks. This approach aims to provide results comparable to larger systems while being more economical and flexible.

How to Use Sakana AI

Sakana AI has made its innovative AI models accessible to developers and researchers through various platforms, allowing for seamless integration into a wide range of applications.

Accessing the Models

  1. Hugging Face: Sakana AI’s models are available on the popular Hugging Face platform. Users can visit the company’s Hugging Face page, select the desired model (such as EvoLLM-JP or EvoVLM-JP), and use it directly on the platform’s interface or integrate it into their applications using the provided APIs.
  2. GitHub: For those who prefer a more hands-on approach, Sakana AI has open-sourced its models and techniques on GitHub. Users can clone the desired repository, such as the evolutionary-model-merge repository for model merging techniques, install the necessary dependencies, and run the models using the provided scripts and examples.

Collaboration and Customization

In addition to accessing pre-existing models, Sakana AI also offers collaboration opportunities for custom AI solutions:

  1. Partnerships: Sakana AI collaborates with companies like NTT to develop AI constellations, which are architectures where multiple small AI models work together to solve complex problems. This approach allows for tailored solutions that address specific business needs.
  2. Custom Models: Companies can work directly with Sakana AI to develop custom models tailored to their specific requirements. This is particularly useful for organizations seeking proprietary AI solutions to gain a competitive edge.

Use Cases

Sakana AI’s models can be applied across a wide range of domains, unlocking new possibilities in various industries:

  1. Healthcare: AI models can be employed to analyze medical images, personalize treatment plans, and accelerate drug discovery processes.
  2. Finance: Leverage AI for real-time financial data analysis, investment decision-making, and risk management.
  3. Language Processing: Utilize large language models for tasks such as translation, summarization, and content generation, enabling seamless communication across linguistic barriers.
  4. Image and Video Processing: Leverage Sakana AI’s vision-language models and image generation capabilities for applications such as visual content analysis, captioning, and content creation.


With a valuation expected to exceed $1 billion and significant funding from prominent investors like Lux Capital, Khosla Ventures, Sony Group, NTT Group, and KDDI CVC, Sakana AI is poised to become one of Japan’s fastest-growing AI startups. By combining the expertise of former Google researchers with innovative, nature-inspired techniques, Sakana AI is pushing the boundaries of what is possible in the realm of artificial intelligence.

As the world embraces the transformative power of AI, Sakana AI’s evolutionary approach offers a unique and promising path forward. By harnessing the wisdom of nature and leveraging cutting-edge techniques like model merging and evolutionary algorithms, this pioneering company is ushering in a new era of AI innovation, where adaptability, efficiency, and cost-effectiveness are no longer compromised for performance.

Whether you are a developer, researcher, or business leader, Sakana AI’s offerings present an opportunity to unlock the full potential of AI and drive innovation across industries. With a strong focus on ethical and responsible use of AI, Sakana AI is not only redefining the boundaries of what is possible but also setting a standard for the responsible and sustainable development of this transformative technology.
