<p>OpenAI dropped GPT-5.5, so we did the only reasonable thing: went live immediately and tried to break it.</p><p><br></p><p>In this off-the-cuff Neuron Live, Corey and Grant walk through OpenAI&#39;s GPT-5.5 release notes, benchmark claims, rollout details, and early access reactions before testing the model live across coding, reasoning, creativity, web research, and absurd prompt challenges. We also compare a few GPT-5.5 responses against Claude Opus 4.7, test Codex, build a new version of Cat Doom, and ask the important questions, like whether a sentient vending machine that only dispenses expired tuna salad deserves to live.</p><p><br></p><p>In this episode, we cover:</p><p><br></p><p>• What OpenAI says is new in GPT-5.5</p><p>• GPT-5.5’s improvements in coding, computer use, research, and knowledge work</p><p>• Early benchmark results across Terminal-Bench, GDPval, Frontier Math, BrowseComp, and scientific research tasks</p><p>• Why token efficiency may matter as much as raw intelligenceGPT-5.5’s rollout across ChatGPT, Codex, Plus, Pro, Business, and Enterprise</p><p>• Live Codex testing with a one-shot Cat Doom game buildCreative stress tests involving palindromes, time-traveling potatoes, dystopian vending machines, and Lord of the Rings product reviews</p><p>• First impressions of whether GPT-5.5 feels meaningfully different from GPT-5.4 and Claude Opus 4.7</p><p><br></p><p>This was not a formal benchmark. It was a first-contact livestream: messy, fast, weird, and exactly the kind of test we like.</p><p><br></p><p>Subscribe for more AI breakdowns, live model tests, beginner-friendly explainers, and weirdly useful prompt experiments from The Neuron.</p><p><br></p><p>Sign up for The Neuron newsletter: <a href="https://www.theneuron.ai/" target="_blank" rel="noopener noreferrer">https://www.theneuron.ai/</a></p><p><br></p><p>Follow along for more AI news, analysis, and live experiments.</p>
