离开 Claude 数月后，Opus 5.5 让我回归
做法与步骤
- 作者离开 Claude 并非因为变笨，而是因为啰嗦、含糊其辞、在不必要的任务上爱说教，于是把日常工作迁到 Codex。
- Anthropic 发布 Opus 5.5：比 Opus 5 便宜 40%、更快，并采用所谓根本不同的对齐方法。
- 作者用一周真实工作测试，包括四个长时间运行的智能体任务、ChatPRD 首页重设计、SVG 基准测试和一次坚决拒绝。
- Opus 5.5 成为作者前端原型设计的首选工具，但在某些方面仍让他失望。
- 作者发现一项他未曾预料的能力，其模型栈中其他模型无法匹敌。
- Opus 5.5 曾直接拒绝作者，这反映了 Anthropic 安全立场在实际中的落地情况。
对实践的启示
对做 AI 应用的人：智能体任务的成本比单次提示更关键，Opus 5.5 的降价和速度值得重新评估；前端原型可优先考虑它，但需留意其仍存在的短板和拒绝行为。
作者承认的反方与局限
作者仍有两件事让他有点抓狂，且 Codex 在某些方面依然胜出，他最终采用混合模型栈。

I’ve been off Claude for months. Not because it got dumb, but because it got annoying. The rambling, the hedging, the preachy little disclaimers on tasks that didn’t need them. I moved most of my daily work to Codex and I didn’t miss it. Then Anthropic shipped Opus 5.5: 40% cheaper than Opus 5, faster, and with what they’re calling a fundamentally different alignment approach. I ran it for a week across real work, including four long-running agentic tasks, a full ChatPRD homepage redesign, an SVG benchmark, and one very firm refusal, and I’m ready to give you the honest verdict. There’s a lot to like. There are still two things that drive me a little crazy. And there’s one capability I genuinely wasn’t expecting.
What you’ll learn:
- Why I walked away from Claude entirely, and what it took for me to come back
- The real cost math on Opus 5.5 and why pricing matters more for agentic work than single prompts
- What happened when I ran four long-running agentic tasks, including one that tried to manipulate Claude mid-run
- Why Opus 5.5 is now my go-to for frontend prototyping, and where it still lets me down
- The one capability I genuinely didn’t see coming, and no other model in my stack can match it
- The moment Opus 5.5 told me flat-out no, and what that says about where Anthropic’s safety posture actually lands in practice
- Where Codex still wins, and how I’m splitting my model stack after a full week of testing
