Episode description as stored
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 — In this episode: (00:00) Why I stopped using Claude (01:02) What Anthropic says Opus 5.5 is (01:54) Cost, speed, and benchmark overview (03:20) Safety, alignment, and the cybersecurity limits (05:02) How I AI bench (05:39) Voice test: is it actually not annoying? (07:54) Long-running agentic task results (10:50) Frontend prototyping (17:23) Writing voice and email (19:41) SVG illustrations (20:46) Video editing (21:42) My verdict: what it’s good at, what it still isn’t — Tools referenced: • Claude Opus 5.5: https://www.anthropic.com/claude-opus-5-5 • ElevenLabs MCP connector: https://elevenlabs.io/mcp • Codex (OpenAI): https://openai.com/codex — Where to find Claire Vo: ChatPRD: https://www.chatprd.ai/ Website: https://clairevo.com/ LinkedIn: https://www.linkedin.com/in/clairevo/ X: https://x.com/clairevo — Production and marketing by https://penname.co/ .
