I Made Opus 5.5 and Fable 5.1 Build the Same Marketing Campaign (RAW RESULTS)

Start your Major Account today: https://www.major.build/?utm_source=y... I gave the exact same marketing campaign to Opus 5 and Fable 5.1 and built it twice inside Major, changing only the model. One costs twice as much per token, so I put both raw outputs side by side to see if paying double actually bought anything. You’ll see how I pick which model goes on which agent, and why I run it all from one place. Major is free to sign up: https://major.build
