Seriously, this is an astounding achievement by GPT-6 Astra. https://kenforthewin.github.io/blog/posts/llm-nethack-ascension/#run=astra-3&frame=0&turn=1 (GPT-6 Astra completed NetHack on its third attempt. NetHack pioneered the roguelike genre and remains one of the games best known for its difficulty. I played it extensively but never finished it.)
