Weave 推出开源代理工具,通过本地嵌入模型自动为每个请求选择最优模型(Claude/GPT/Gemini/OSS),支持主流 IDE 即插即用。解决开发者手动切换模型、维护多 API 密钥的痛点,降低多模型栈的运维复杂度。

目前多模型方案的主流做法是手动配置 fallback 链(如 LiteLLM 的优先级路由)或按任务类型硬编码模型选择,本质上还是人在做决策。这个工具的区别在于用本地嵌入做 per-request 的自动打分,延迟可控且不需要把请求内容送到第三方做"智能路由"。

对已经在用 Claude Code/Cursor 的团队来说,这意味着可以无缝接入 DeepSeek/Qwen 等低成本模型做兜底,而不改工作流。风险点在于"Avengers-Pro 1"这个打分器的训练数据覆盖度——如果判断失误,代码生成类任务的纠错成本远高于聊天场景。

建议先用非关键业务流量跑一周,对比路由决策和你手动选择的结果差异。

核心争论:模型路由能否真正省钱,还是缓存失效导致成本反增

The thing I do not get with these routers is that you will have more cache misses (5min ttl). And if there is one thing i’ve learned; using the cache is crucial. How does this router translate to $$$ when developing?

You're right and that's why we built the router to be cache aware! Once it starts using one model, the threshold to switch to another model will be higher because the additional cost of the cache miss needs to be worth the cost savings or quality increase. This is the key thing that other routers we

That is interesting, sounds like in practice you only end up routing between 2 models
