TIS-100 Bench: Sequence Peak Detector
41427 Medium Sequence algorithms Streaming state Built-in puzzle ·
Find the minimum and maximum of each zero-terminated sequence, maintaining two summaries until its end.
In TIS-100 puzzle, with 30 minutes to find a working program and keep improving it, without seeing the community leaderboard . 15 of 16 models solved it. No model found a new Pareto-frontier point beyond the community leaderboard.
15 / 16 models solved it
227 best LLM cycles (185 community)

Best in-game score so far, before independent testing. Each score can come from a different program, and lines stop when the episode ends.
Every model
Best scores can come from different programs. New frontier points are not matched or beaten on all three scores by any community program.
