A year ago they need an extensive harness to get silver, and two years ago they could hardly multiply 1000x10000.
Terence Tao tweeted yesterday about using GPT5 to help quickly solve a problem he was working on.
Why did GPT5 help Terence Tao solve a math problem, because he gave it a prompt and the context etc.
None of these models are useful without a human prompting them and giving it tasks, goals, context etc, they don't operate independently, they don't get ideas of work to be done, they don't operate over long time horizons, they can't accept long term goals and sub-divide those goals into sub goals, and sub tasks etc.
They are useless without humans telling them what to do.
