Opus 5 generates really good code and terminal commands though. It's just bad at the accompanying text it tells you. These benchmarks don't grade the text generation of the response I don't think, only the task outcome.

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
