DAIR.AI 的 Elvis Saravia 建议企业从自建 harness 入手掌控智能技术栈，先构建 evals 再沿栈向下推进，因为开源模型运行和调优成本仍然很高。他认为自建 harness 能带来可选性、解锁能力，并帮助判断下一步该在技术栈何处投资。Vercel CEO Guillermo Rauch 呼应称应掌控 harness、数据、连接与运行时，让本地模型持续繁荣。
Own your intelligence stack, folks!
I will never get tired of saying this. Your business's very existence is at play here.
But you don't have to do this all at once if you can't afford it. I mean, open models are still very expensive to run and tune.
If you want to start somewhere, I suggest the harness. Build your evals and quickly move down the stack.
The great part about building your own harness is that it gives you optionality, unlocks capabilities, and helps you measure where else in the intelligence stack you need to invest next.
So while open-source was an alternative in the old era, today it is how you survive and thrive in the age of intelligence.
Own your intelligence. Anyone that opposes this has something to sell you (perhaps your own intelligence back to you.) Local models need to continue proliferating. The “absolute unit” massive models may be out of reach for now locally, so your best option is to, indeed, keep your options open. Own your harness, data, connections, runtime: your agents. Embrace open source.在 X 查看被引用的帖子
