I’ve read enough model comparison posts to know how most of them go. Someone pulls two benchmark tables, screenshots them side by side, and calls it a review. I wanted something less theoretical. So I picked one real build task, gave the exact same prompt to Claude Fable 5 and GPT-5.6 Sol, and just watched what each one actually did no cherry picking, no re rolling until I got a good answer.
What I found lines up with the numbers in a way I didn’t expect, but it also exposed a few things no spec sheet tells you.
