About the product
Sakana AI | Sakana Fugu is an advanced AI platform developed by Sakana AI, a Tokyo-based artificial intelligence research company focused on building next-generation AI systems inspired by nature, evolution, and collective intelligence. Sakana AI is known for its research in autonomous AI agents, model merging, scientific discovery, and multi-agent intelligence. One of its most notable products is Sakana Fugu, a powerful multi-agent AI model system designed to handle reasoning, coding, scientific analysis, engineering tasks, automation, and complex problem-solving through a single model API.
Unlike a traditional chatbot, Sakana Fugu is designed to dynamically coordinate multiple AI agents and models to complete difficult tasks more effectively. The platform includes two main models: Fugu, a fast and balanced model suitable for everyday use, and Fugu Ultra, a more powerful version built for advanced reasoning, coding, science, software engineering, and high-performance task execution.
Based on benchmark comparisons, Fugu Ultra shows very strong performance against leading frontier AI models such as GPT 5.5, Gemini 3.1 Pro, Opus 4.8, Fable 5, and Mythos Preview. It performs especially well in Terminal Bench 2.1, CharXiV Reasoning, GPQA-D, and LiveCodeBench, showing excellent capability in coding, reasoning, scientific problem-solving, and technical workflows. Fugu also delivers strong results, especially in GPQA-D, where it matches Fugu Ultra with a very high score. While Fugu Ultra does not lead every benchmark, it remains highly competitive across multiple advanced AI evaluation tasks.
Sakana Fugu is ideal for developers, AI researchers, software engineers, students, data scientists, startups, automation builders, research labs, and companies that need a powerful AI system for coding, analysis, research, technical problem-solving, and agentic workflows. It is especially useful for users who need more than a simple chatbot and want an AI model capable of handling complex multi-step tasks with strong reasoning and execution ability.
