$104 Later, Here's the Claude Model I'd Use
Sonnet 5.5 vs Opus 5.5 vs Fable 5.1: one prompt, three games, and a very different price tag for each. 🎁 Grab the mini golf prompt, all three playable games and their source code for free: https://skool.com/leonvanzyl 🚀 Agentic Labs — exclusive AI coding courses, live Q&As, workshops & deep dives: https://skool.com/agentic-labs On paper, Sonnet 5.5 scores close to Opus 5.5 on agentic coding at about half the price. Benchmarks are one thing, but real builds are what count. So I gave Sonnet 5.5, Opus 5.5 and Fable 5.1 the exact same prompt in Claude Code to build a polished 3D mini golf game that runs in the browser. Then I compared the quality, speed and cost of every result. You'll see all three games played, windmill and dinosaur holes included, along with how long each build took and what it cost. The surprise: Sonnet 5.5 was not the budget pick I expected it to be. ▶️ Watch next: Claude Fable 5 Built This in Claude Code and I'm Blown Away: https://youtu.be/I3PYGi_tGy0 ⏱️ Chapters 0:00 Sonnet 5.5 vs Fable 5.1 0:52 Sonnet 5.5 Max Mode Warning 1:10 The 3D Mini Golf Prompt 2:20 Sonnet 5.5 in Claude Code 4:08 Fable 5.1 Game and Cost 6:09 Opus 5.5 Game and Cost 8:03 Sonnet 5.5 Game and Cost 10:18 Opus 5.5 vs Sonnet 5.5 Connect X: https://x.com/leonvz TikTok: https://www.tiktok.com/@leonvanzylofficial Business & sponsorships: leon@cognaitiv.ai
