■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

Sakana AI has released Fugu Ultra v1.1, claiming performance gains of up to 7.9 points over the previous version. The updated model router reportedly outperforms Claude's latest offering without including it in its routing pool.

The new version introduces a Claude Code-compatible endpoint, expanding integration options for developers. Sakana's claims remain unverified by independent benchmarks, following a pattern common in the competitive AI model router space. Fugu Ultra functions as a routing system that directs queries to different AI models based on task requirements. The performance improvements suggest refinements to its selection algorithms or underlying model integrations. The service continues to face regional restrictions, remaining unavailable in the European Union due to regulatory constraints. Sakana has not provided detailed technical breakdowns of the improvements or specific benchmark methodologies used in the v1.1 testing.
