Opus 5.5 vs Sonnet 5.5 tested both with the same prompt and the results were crazy Opus 5.5 consumed $5.20 to finish everything in 28 mins meanwhile, Sonnet 5.5 consumed only $2.9 to finish everything in 20 mins lol if you prefer cheaper and faster then Sonnet is best but no models is near Opus 5.5 atm what do you think?
