Is Sakana AI Free?


Artificial Intelligence (AI) has revolutionized various industries, and the race to develop cutting-edge AI models is intensifying globally. At the forefront of this exciting frontier is Sakana AI, a Tokyo-based startup founded by former Google researchers David Ha and Llion Jones. With a unique approach inspired by nature, Sakana AI is breaking down barriers and pushing the boundaries of AI innovation.

What is Sakana AI?

Sakana AI is a pioneering AI startup that distinguishes itself by leveraging nature-inspired techniques to develop innovative AI models. At the core of its approach are three key innovations:

  1. Model Merging: This technique involves combining multiple AI models to create more powerful and adaptable systems. Sakana AI has used this approach to develop high-performance Japanese Large Language Models (LLMs) and Vision-Language Models (VLMs).
  2. Evolutionary Algorithms: Inspired by the principles of natural selection, Sakana AI employs evolutionary algorithms to automatically select and merge the best models. This method allows for the creation of sophisticated AI systems more efficiently and cost-effectively.
  3. Swarm Intelligence: Drawing inspiration from 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.

Is Sakana AI Free?

Sakana AI offers both free and potentially paid options for accessing their AI models and technologies, catering to a diverse range of users and industries.

Free Access:

Open-Source Models: Sakana AI has released several of their models on platforms like Hugging Face and GitHub, making them accessible for free. These include:

  1. EvoLLM-JP: A Japanese Large Language Model.
  2. EvoVLM-JP: A Japanese Vision-Language Model.
  3. EvoSDXL-JP: An Image Generation Model.

Hugging Face and GitHub: Users can access and use these models directly on Hugging Face, which provides a platform for building, sharing, and collaborating on machine learning models. Additionally, Sakana AI’s repositories on GitHub allow users to clone, modify, and use their models, promoting open-source collaboration and development.

Potential Paid Options:

While the core models are available for free, there may be additional services or advanced features that could require payment:

  • Enterprise Solutions: For businesses requiring advanced AI tooling, enhanced security, and support, Sakana AI might offer enterprise-grade services that come with a cost. This is a common practice in the AI industry, where basic models are free, but enterprise solutions and customizations are paid services.
  • Custom Collaborations: Sakana AI collaborates with companies for custom AI solutions, which likely involve contractual agreements and payments. These collaborations are tailored to specific needs and may include proprietary model development and integration.

Why Sakana AI?

Sakana AI’s unique approach to AI development sets it apart from other players in the industry. By drawing inspiration from nature, the startup has developed innovative techniques that have contributed to its success and growth.

  • Innovative Techniques: Sakana AI’s nature-inspired methods, such as model merging, evolutionary algorithms, and swarm intelligence, have proven effective in creating powerful and adaptable AI models.
  • Funding and Partnerships: The startup has secured significant funding, raising $30 million in a seed funding round led by prominent investors like Lux Capital, Khosla Ventures, Sony Group, NTT Group, and KDDI CVC. Additionally, Sakana AI has obtained a government grant for supercomputer time and is exploring projects with major Japanese firms like NTT and Sony Group Corp.
  • Japanese Market Focus: With a strong focus on the Japanese market, Sakana AI aims to establish Tokyo as a prominent center for AI innovation, similar to how OpenAI has positioned San Francisco and DeepMind has positioned London. The company is also targeting government agency work and subcontracts in Japan’s defense industry.
  • Rapid Growth: With a valuation expected to exceed $1 billion, Sakana AI is on track to become one of Japan’s fastest-growing AI startups, solidifying its position as a leader in the field.


Sakana AI’s innovative approach to AI development, combining cutting-edge techniques with nature-inspired principles, has positioned the startup as a trailblazer in the industry. By offering both free access to its open-source models and potential paid enterprise solutions, Sakana AI caters to a diverse range of users and industries. With significant funding, strategic partnerships, and a focus on the Japanese market, Sakana AI is poised to make a substantial impact on the global AI landscape, breaking down barriers and pushing the boundaries of what’s possible in the world of artificial intelligence.
