My playbook for growing a $1M AI agency: https://app.aiautomationsociety.ai/opaa-ads-optin My FREE resources: https://www.skool.com/ai-automation-society/about?el=fable-vs-sol-5.6&hcategory=youtube-videos&utm_campaign=free-group My Tools💻 FREE MONTH voice to text: https://get.glaido.com/nate Code NATEHERK for 10% off VPS (annual plan): https://www.hostinger.com/vps/claude-code-hosting I spent all day running GPT-5.6 Sol against Claude Fable 5, side by side, on real work instead of just staring at benchmarks. I put them head to head in Codex and Claude Code on browser games, interactive websites, and open-ended builds, then ran a bunch of quick one-off tasks over the API to see how they compare on speed, cost, and reliability. My take: Fable is the better manager and the more creative, capable model, while Sol is a really good worker that ships fast and costs a fraction of the price. Watch to see where each one wins and how I decide which model to reach for.
