switching model providers is easy switching harnesses is less so model providers want to lock you ...
TL;DR · AI 摘要
Harrison Chase指出切换大模型供应商容易，但切换AI应用层的‘harness’（如LangChain）更难；厂商正通过私有harness锁定用户，亟需开放标准。
核心要点
- 模型提供商易替换，但harness层迁移成本高、生态碎片化
- 厂商将harness作为锁定用户的手段，而非单纯资源管控工具
- 推动开放、可互换的harness标准是避免厂商锁定的关键路径

switching model providers is easy — switching harnesses is less so
model providers want to lock you in via harness
we need open harnesses!
They could accomplish that by just enforcing limits on the actual resource usage (which they already do)

TBH I don't agree with your take. I don't think Athropic's desire to control the harness is about keeping resource usage under control. They could accomplish that by just enforcing limits on the actual resource usage (which they already do) -- if some third-party harness is
