Description
Sakana Fugu Ultra is a performance-optimized multi-agent AI model designed for hard technical, research, security, and analytical workloads. It coordinates a deeper pool of expert agents than the standard Fugu model, allowing it to focus on maximum answer quality for complex tasks. The model is available through the same OpenAI-compatible API as Sakana Fugu, making it easier to integrate into existing tools, developer workflows, and AI applications. Fugu Ultra is especially useful for coding, advanced code review, Kaggle competitions, paper reproduction, cybersecurity assessments, literature reviews, patent research, and long-running autonomous workflows. Instead of requiring users to choose individual models or define agent roles, Fugu Ultra dynamically assembles and coordinates the agents that are best suited for each task. Its approach is grounded in learned model orchestration research, including TRINITY and the Conductor, which explore how multiple AI systems can collaborate more effectively. Organizations can also control which providers or models participate in the agent pool to support privacy, compliance, and internal policy requirements. Fugu Ultra is positioned for high-value tasks where deeper analysis, stronger reasoning, and better reliability matter more than speed alone. Sakana Fugu Ultra gives developers, researchers, and enterprises a way to use frontier-level multi-agent intelligence through one managed endpoint.
Description
Sakana Marlin serves as the Virtual Chief Strategy Officer for Ultra Deep Research, designed to allow artificial intelligence to manage research tasks while enabling human experts to concentrate on making strategic decisions. Far from being just another research assistant, this autonomous agent tackles the extensive strategic research responsibilities typically shouldered by a Chief Strategy Officer and a small research team, which would usually take weeks to complete. With the support of Sakana AI’s advanced reasoning framework, Sakana Marlin is capable of scaling inference-time computations, allowing it to engage in up to eight hours of continuous and independent reasoning. Once a research topic is established, it operates autonomously without the need for further human assistance, continuously generating hypotheses, collecting data, browsing the web, and resolving any inconsistencies it encounters. Its emphasis is not on rapid text generation; rather, it prioritizes long-term, efficient reasoning that systematically tests hypotheses and conducts web research to distill the most pertinent information from an overwhelming volume of data. Sakana Marlin transcends mere summarization, offering a nuanced and comprehensive understanding of complex subjects.
