Sakana AI Fugu: Multi-LLM System Rivals Anthropic Models

A Japanese company called Sakana AI has developed a new AI tool called Fugu. This system takes many existing AI models and makes them work together as a team. What's interesting is that the company claims this multi-model approach matches or even beats the top AI tools available, including advanced "frontier models" from companies like Anthropic. Fugu is designed to feel like a single model to the user, even though it's orchestrating multiple models behind the scenes. It uses a process of selection, delegation, checks, and synthesis to generate a single final reply. There are two versions: a normal Fugu and a stronger one called Fugu Ultra. The reported scores show both versions competing closely with leading single models in various tests. This matters because it suggests a new, potentially more efficient way to build powerful AI systems.
