GLM 5.2 reaches 3rd place on the official ProgramBench leaderboard

A Reddit post from one of the authors says GLM 5.2 has moved up to 3rd place on the official ProgramBench leaderboard, which tests extremely long-horizon agentic coding: the model must reconstruct source code from only a binary executable and a README.

The author says the benchmark is still missing many open- and closed-source models, but the result is still impressive. They also highlight a near miss on the first solved instance, cmatrix, where GLM rebuilt the program almost perfectly and scored 99.8% on tests, missing only the text Computer locked. in the lock-mode output.

They plan to release all trajectories on programbench.com soon.
