Grid-Bench T16 D2 exact: leaderboard
Grid-Bench multidimensional cellular-automaton state tracking, prompt 0.4; September16–24 collection, one response with 128000 combined tokens, no tools, 7200-second deadline. High effort for five models; MiniMax M2.5 native always-on thinking. Exact-output counts retain invalid responses and all failures. NAIRR routes for GPT/Claude, native Bedrock for GLM/Kimi/MiniMax; Appendix C pins identities. 16 update steps, dimension 2; 64 main instances. Metric: Exact answers (out of 64). Higher is better.
