Terminal Bench 4.0 did not introduce new questions. All tasks were public for a while. If you look at GLM 5.2, which is using the same base model as 5.3, but was released prior to most tasks, it does extremely horribly on terminal Bench 3.0 (4 to 8 times worse than every other model) - source: https://benchlm.ai/benchmarks/terminal-bench-3
