Sakana AI launched Fugu on June 22, 2026 — a multi-agent orchestration system delivering frontier-level performance through a single OpenAI-compatible API.
Fugu dynamically orchestrates the world’s best models to tackle complex multi-step tasks. Grounded in two ICLR 2026 papers: TRINITY and Conductor — learned model orchestration replacing hand-designed workflows.
Two variants:
- Fugu: balanced performance with low latency for everyday coding, review, chatbots
- Fugu Ultra: maximum answer quality for hard multi-step problems; deeper expert agent pool
CEO David Ha positioned Fugu as hedge against US export controls that revoked global access to Anthropic Mythos 5 and Fable 5 (June 12, 2026).
Benchmark claims (vendor-reported): LiveCodeBench 93.2 vs Fable 5’s 89.8; GPQA-D 95.5; SWE-Bench Pro 73.7 vs Fable 5’s 80.0.
Available globally except EU/EEA (GDPR alignment pending). Pricing from 5/$30 per million tokens for Fugu Ultra.
Sakana Series B valuation: $2.6B (late 2025). Founders: Llion Jones (Attention Is All You Need co-author), David Ha (ex-Google Brain).
