Sakana AI

Sakana AI is a Tokyo-based frontier AI research and development company focused on building efficient, adaptive, and nature-inspired AI systems. Founded in 2023 by David Ha, Llion Jones, and Ren Ito, the company develops foundation models, multi-agent systems, autonomous AI research technologies, and AI solutions for enterprises and government organizations.

One of Sakana AI’s major commercial products is Sakana Fugu, a multi-agent orchestration system that coordinates multiple frontier foundation models to solve complex tasks. Rather than relying on a single model, Fugu dynamically orchestrates AI agents and models to improve performance across areas such as coding, mathematics, and scientific reasoning.

Sakana Fugu is available through an API and offers both subscription and pay-as-you-go usage. Its current subscription tiers include Standard at $20/month, Pro at $100/month, and Max at $200/month, while production workloads can use consumption-based token pricing.

Sakana AI also develops Sakana Marlin, its commercial AI product focused on autonomous execution of sophisticated workflows. Marlin brings together the company’s research in long-horizon reasoning, multi-model orchestration, and autonomous agents to execute complex business tasks. It is available through pay-per-use and Pro, Team, and Enterprise plans.

The company has also developed Sakana Chat, a Japanese-focused AI chatbot powered by its Namazu large language models. Sakana Chat provides web search and Japanese-language answers and is currently available for free. Users can access it without registering an email address, while registration enables conversation history and higher usage limits.

Sakana Translate extends Sakana Chat with AI-powered translation, proofreading, and question-answering. It supports Japanese, English, and Chinese in both directions and is available as a free web application.

Sakana AI is also known for The AI Scientist, a research system designed to automate parts of the scientific discovery process, as well as the Darwin Gödel Machine, which explores AI systems capable of recursively improving their own algorithms. Its broader research portfolio includes multi-agent orchestration, evolutionary AI, and efficient model development.

The company works with major Japanese enterprises and public-sector organizations, including financial institutions and government agencies. Its Applied Team focuses on deploying frontier AI technology in areas such as finance, defense, and enterprise operations.
