About this episode

In this episode, Claire Vo discusses her testing of OpenAI's GPT 5.5 and its applications in various real-world scenarios.

In this mini episode, I break down OpenAI’s new GPT 5.5 and GPT 5.5 Pro after weeks of early testing. I walk through three real jobs I threw at the model: building an app for me to teach my second grader more advanced subtraction concepts, tackling a tech debt problem in the ChatPRD codebase, and hacking into a proprietary Bluetooth pixel display that every other model had failed me on. My verdict: higher intelligence, better efficiency, and genuinely autonomous long-running loops that change what I think is worth tackling. What you’ll learn: How I think about GPT 5.5 Pro’s pricing vs engineering time, and when I believe the “intelligence tax” is worth paying Why I treat GPT 5.5 as a developer model first, and why I couldn’t find a consumer use case that justified its intelligence The exact prompt pattern I use to unlock a long-running autonomous subagent loop How I got a near-six-hour autonomous run to one-shot 98% of edge cases in a migration over millions of chat threads and drop my Sentry error rate to the floor Why I’m now throwing GPT 5.5 at tech debt, flaky tests, and security backlogs first How I combined a Bluetooth packet sniffer and GPT 5.5 to reverse-engineer a…
