Epoch AI(@EpochAIResearch):We recorded over a thousand runs of Slay the Spire and its sequel for our recent benchmark, SpireClimb. Over the coming weeks, we'll publish them all on our YouTube channel, complete with subtitles showing the models' in-game thinking. Check out the run that produced the clip: https://t.co/sKi2VdOUIu And the playlist where we're uploading all videos: https://t.co/mZ1pnwXe16 Rather than being recorded live, the videos are reconstructed from the models’ play data (inputs and thinking). We don't plan to update the playlist with videos from future models' runs on SpireClimb, but we hope this archive offers interesting insights into how current models play the game.

Six months ago, frontier AI models could barely beat Slay the Spire. Now, according to our new SpireClimb benchmark, they win 90%+ of runs at the easiest difficulty, and up to 20% of runs at the hardest.
