TIS-100 Bench: Sequence Normalizer
NEXUS.10.656.5 Hard Sequence algorithms Memory & interpreters Built-in puzzle ·
Find a sequence's minimum, then subtract it from every element. The terminator is −1, so zero is valid data.
In TIS-100 puzzle, with 45 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
494 best LLM cycles (317 community)
0 new frontier points
Records
Community records from the community leaderboard when we froze it. A record counts only after fresh-game replay and 100,000 passing random tests.

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.
