Sakana Fugu Ultra now available on AI Gateway
Sakana Fugu Ultra from Sakana AI is now available on AI Gateway.
Fugu Ultra is built on a pool of publicly accessible frontier models, rather than running as a single model. It coordinates several models, routing work to 1-3 agents depending on the problem and combining their results into a single answer.
Based on reasoning and scientific benchmarks, Fugu Ultra has capabilities similar to those of Claude Mythos Preview and Fable 5.
To use Fugu Ultra, set `model` to `sakana/fugu-ultra` in AI SDK:
1import { streamText } from 'ai';2const result = streamText({3 model: 'sakana/fugu-ultra',4 prompt: 'Review this pull request and flag correctness bugs.',5});AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in custom reporting, Zero Data Retention support, budgets for API keys, and more.
AI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on Bring Your Own Key (BYOK) requests.
