为什么值得看
文章对比了个人开发者在家 AI 编程的三种低成本路径：本地自托管、按需 API、混合策略，核心变量是对未来一年硬件和模型迭代的信任度。对预算有限但想深度使用 AI 编程的工程师有直接参考价值。
编辑判断
这篇文章的真正价值不在三种方案本身，而在于它戳破了一个普遍幻觉：很多人买 4090/5090 想本地跑大模型，却高估了自己的实际使用频率。HN 评论区里大量用户坦承"买了机器后闲置"，这和健身房年卡陷阱一模一样。
更务实的策略可能是反直觉的——先按最高 API 成本跑三个月，算出真实 token 消耗和任务类型，再决定要不要买硬件。对于以代码补全为主的场景，Claude Code 或 Cursor 的订阅制其实比自托管更省；只有涉及大量私有代码的批量重构或夜间 CI 任务，本地机器才能摊薄成本。
如果你正在犹豫要不要装机，建议先用 Ollama + Continue.dev 跑一周真实工作流，记录 GPU 占用曲线，这个数字比任何理论分析都诚实。

核心争论：本地自托管 vs API 按需付费：隐私溢价与电力成本是否值得
I find just going via Deepseek's platform API directly, using their V4 flash model, and hooking into a harness like Opencode more than acceptable. Think I've spent maybe $10 over a couple of weeks. I did explore self-hosting models but hardware right now is just too expensive.
Directly at DeepSeek? It was my understanding (but I didn't check) that some other AI operators were providing (some of?) DeepSeek's model for cheaper prices. Still, that's interesting. What do you get for that price? Only coding, or also e.g. image generation?
> The first is to self host. You buy the machine, run open source models locally, and pay nothing per token after that. Power is not free. What I’ve found is that you’re basically paying a premium for privacy, and that’s worth it for me.
