Sakana AI’s Fugu Ends Vendor Lock-In with Multi-Agent Orchestration

Sakana AI launched Fugu on June 22, 2026, a multi-agent orchestration system designed to shake up AI workflows. It calls on a pool of specialized models to complete multi-step tasks through a single, OpenAI-compatible API endpoint. No more juggling multiple vendors or APIs.

Fugu acts as a conductor model. It decides if a query can be handled directly or requires assembling a team of expert agents. This dynamic orchestration is driven by learned collaboration patterns, not brittle hard-coded workflows. It’s smarter AI management.

There are two tiers: standard Fugu balances latency and quality for everyday tasks. Fugu Ultra handles complex, high-stakes jobs. Ultra’s prowess is proven—it scored 73.7 on the SWE-Bench Pro benchmark, rivaling Anthropic’s Fable 5 and Mythos Preview.

Fugu’s architecture tackles vendor lock-in and export control risks head-on. Users can swap out or opt out of specific models or providers. This flexibility creates a fail-safe AI ecosystem where specialists and verification roles reduce error risks.

Notably, Fugu is not yet available in the EU and EEA due to regulatory compliance hurdles. Still, its core mission is clear: to turn multiple AI specialists into a single manageable system for teams. It simplifies integration while maximizing reliability and independence.

Fugu’s design roots trace to two ICLR 2026 papers—TRINITY and Conductor. Its benchmarks cover a wide range: SWE-Pro, TerminalBench, LiveCodeBench, Humanity’s Last Exam, GPQA-D, SciCode, Long-context reasoning, and MRCRv2. The system proves competitive with frontier public models.

By delivering an OpenAI-compatible API, Sakana AI lets developers plug Fugu into existing workflows without friction. This alone could shift AI adoption, breaking dependence on single providers and enabling modular, resilient AI stacks.

Fugu is a rare breed: a multi-agent AI system that doesn’t just coordinate but optimizes and verifies. In a market crowded with single-model solutions, Fugu offers a smarter path to managing AI complexity and risk.
