Sakana AI updates its model router

The new Fugu Ultra v1.1 claims to be faster and more accurate than the previous version. Sakana says it now outperforms the Fable 5 model, even though Fable is not part of their current selection.

This update adds support for Claude Code endpoints. This change makes it easier for developers to connect their tools to the router.

The service is still not available to users in the European Union. We are waiting for independent tests to confirm these performance claims.
