You can pay for a powerful AI model and still spend your evening fixing its work. A few days ago, I promised you a practical workflow for GPT-6 Astra and Claude Fable 5.1. I want this next guide in our series to help you finish a job, check it properly and keep a setup you can use again.
The mistakes worth catching are not always obvious. A report can get every calculation right and still recommend something nobody approved. Ask for a better version, and you might get the same mistake in more convincing language. How do you recognise that before you rely on the answer?
We’ll give Astra and Fable the same assignment, then change an approved decision and introduce a misleading instruction. You’ll see what to provide, which settings matter and what to inspect when the answer looks finished. Start in a chat window, then follow the optional steps to build a workflow that reads your files and saves the outputs.
You’ll get the source files, complete prompts, worked examples and checks for all three cases. Use them to build your first workflow and judge both models by the work you can actually use...
