"Diminishing returns", so are you claiming unironically that GPT4.1 can achieve anything Fable 5 can?

Or just that it's so much cheaper that the cost/benefit ratio is better?

Also "finish a task" is also subjective. I can "finish the task" of building a table, but it will be a shitty table. Are you also measuring the quality of the result - which is subjective again?
