I Tested Opus 5 vs. Fable 5. What You Need to Know.

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=Opus-5-vs-Fable-5&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 Claude Opus 5 is benchmarking above Fable 5 on a lot of coding tasks at half the cost per token, so I ran both models through my real workflows to see if that actually holds up. I gave them the same prompts across a bunch of experiments, from fixing bugs in a big codebase to building a landing page, running audience research, and coding a structural simulator. For every run I break down the cost, time, and tokens so you can figure out where each model fits in your own workflows.
