问HN：最佳AI网关是什么？
哪些AI网关表现良好？我们目前直接使用Anthropic的路由器作为我们的AI代理（在val.town上），但正在考虑添加OpenRouter、Vercel AI Gateway或其他完全不同的选项。
我对网关了解不多，只知道它们似乎是新的VS Code分支（也就是说，大家都在做这个）。我粗略的研究告诉我，OpenRouter拥有最多的模型/提供商，但收取5.5%的按需付费平台费用（我们将推理成本转嫁给客户），并且不支持像提示缓存这样的功能。
我们主要使用Cloudflare，我刚刚了解到他们也有一个AI网关——但到目前为止，我找到的“2026年最佳LLM网关”类型的文章都是由……拥有网关的公司发布的。

What AI gateways work well? We currently use Anthropic's router directly for our AI agent (on val.town) but are considering adding OpenRouter or the Vercel AI Gateway, or something else entirely.<p>I know little about gateways except that they seem to be the new VS Code forks (i.e. everyone is doing it). My cursory research tells me that OpenRouter has the most models/providers, <i>but</i> charges a 5.5% pay-as-you-go platform fee (we pass-through inference costs to customers) <i>and</i> doesn't support features like prompt caching.<p>We're mostly a Cloudflare shop, and I learned minutes ago that they, too, have an AI gateway--but so far the "Best LLM Gateway 2026" type articles I've found are published by...companies with a gateway
