GPT-5.2 vs Opus 4.5: The Ultimate Coding Benchmark

A year's worth of code. Built in hours. GPT-5.2 vs Opus 4.5 on my hardest benchmark yet—and both crushed it. I designed this benchmark differently than anything you've seen before. No cherry-picked problems. No simple coding challenges. Instead: a massive, production-grade PRD pulled from an app I actually built—complete with multiple detail pages, AI-powered features like "Scoop" and "Alchemy," cast and crew data, season/episode hierarchies, and streaming service integrations. The results? Yesterday's state-of-the-art (GPT-5.1 Codex Max) couldn't keep up. The new GPT-5.2 Medium delivered surprisingly well for a "recommended" tier. But the real showdown came down to GPT-5.2 Extra High vs Claude Opus 4.5—and both models absolutely crushed it after just one refinement pass. Here's what shocked me most: Opus 4.5 tells you what it's doing. It communicates. It gives you a to-do list, explains its reasoning, and confirms what it understood. GPT-5.2? Just starts coding. No feedback. No confirmation. That distinction matters more than any benchmark score. In this video I cover: The complete benchmark setup and PRD complexity Side-by-side builds across all four models First-pass results and feature completion analysis The "Delta Document" technique that unlocked 90-95% completion Why communication style might be the most important model difference The Alchemy feature build that blew my mind Models tested: GPT-5.1 Codex Max Extra High (yesterday's OpenAI SOTA) GPT-5.2 Medium (recommended tier) GPT-5.2 Extra High (new OpenAI flagship) Claude Opus 4.5 (Anthropic's latest) This is what happens when you stop running toy benchmarks and start testing what actually matters. https://openai.com https://anthropic.com https://claude.ai #GPT52 #ClaudeOpus #AIBenchmark #AICoding #OpenAI #Anthropic 00:00 - Intro 00:53 - The PRD 02:12 - The Preparation 04:06 - Initial Results 10:19 - Side by Side 12:29 - Going Farther 19:39 - Pushing ALL THE WAY 23:08 - Conclusion
