Sakana AI launched Fugu, a multi-agent orchestration system, and said its flagship Fugu Ultra matches the performance of Anthropic’s export-restricted Fable and Mythos models. According to BeInCrypto, the Tokyo-based startup is pitching Fugu as a hedge against vendor lock-in after Anthropic’s June 12 suspension of access to Fable 5 and Mythos 5 under a US export control directive.
Fugu ships in two tiers via a single OpenAI-compatible API and routes requests across a swappable agent pool. Sakana said Fugu Ultra led four of eight benchmarks, including LiveCodeBench at 93.2 and GPQA-D at 95.5.
