Sakana AI 发布 Fugu Ultra v1.1，声称未纳入 Fable 5 仍能击败它

Sakana AI 发布了 Fugu Ultra v1.1，这是其 AI 路由器的更新版本，该路由器将每个查询分配到由公开可用的顶级模型组成的池中。公司声称，相较于 v1.0，性能提升高达 7.9 分，其中 ProgramBench 和 TerminalBench 2.1 的提升最大。据报道，Fugu v1.1 即便在 Fable 5 不在路由器选择池中的情况下，也能击败 Fable 5。所有这些数据均来自 Sakana 本身，目前尚无独立验证。

定价：https://sakana.ai/fugu/ 仍为每百万输入令牌 5 美元，每百万输出令牌 30 美元。Sakana 表示，在将新的顶级模型加入池之前，大约需要两周的训练和评估。该架构在技术报告中有描述：https://arxiv.org/abs/2606.21228。本次更新还增加了支持 Claude Code 的接口：https://console.sakana.ai/get-started，允许从终端直接调用 Fugu。自发布以来，Fugu 已在 OpenRouter 和 Vercel 等平台上可用。

第一版 Fugu 的反响平平：https://the-decoder.com/sakana-ais-fugu-orchestrates-multiple-llms-to-match-anthropics-fable-and-mythos-benchmarks/。评论者指出其令牌使用高、速度慢、效果不佳。Sakana 仍未向欧盟或欧洲经济区提供服务，理由是 GDPR 和“欧盟特定法规”。Ad DEC_D_Incontent-1 Ad

Sakana AI has released Fugu Ultra v1.1, an update to the AI router that distributes each query across a pool of publicly available top-tier models. The company claims performance gains of up to 7.9 points over v1.0, with the biggest jumps on ProgramBench and TerminalBench 2.1. Fugu v1.1 reportedly beats Fable 5, even though Fable 5 isn't part of the router's selection pool. All of these numbers come from Sakana itself, and no independent verification exists yet.

Pricing：https://sakana.ai/fugu/ stays at $5 per million input tokens and $30 per million output tokens. Sakana says it takes about two weeks of training and evaluation before a new top-tier model gets added to the pool. The architecture is described in the technical report：https://arxiv.org/abs/2606.21228. The update also adds a Claude Code-compatible endpoint：https://console.sakana.ai/get-started for calling Fugu directly from the terminal. Since launch, Fugu has been available on platforms like OpenRouter and Vercel.

The first Fugu version got a lukewarm reception：https://the-decoder.com/sakana-ais-fugu-orchestrates-multiple-llms-to-match-anthropics-fable-and-mythos-benchmarks/. Critics pointed to high token usage, slow speed, and poor results. Sakana still doesn't serve the EU or EEA, citing GDPR and "EU-specific regulations." Ad DEC_D_Incontent-1 Ad
