Key point

Sakana AI's multi-model collaborative model, Fugu Ultra, has been released via Vercel's AI Gateway.

Details

Sakana AI's Fugu Ultra is now available on AI Gateway. Rather than a single model, Fugu Ultra is a pool-based model that leverages multiple public Frontier Models.

This model routes tasks to 1–3 Agents depending on the problem type, and combines each model's output to produce a single answer. On reasoning and science benchmarks, it shows performance similar to Claude Mythos Preview and Fable 5.

Through AI Gateway, you can take advantage of the following features:

  • A unified API for calling models
  • Usage and cost tracking
  • Support for retry, failover, and performance optimization
  • Custom reporting and Zero Data Retention support

Users can start using it immediately by setting the model name to sakana/fugu-ultra in the AI SDK, with the provider's pricing policy applied as-is at no additional cost.
