GLM 5.2 playing text adventures
The article evaluates GLM 5.2, showing that it can successfully play text adventure games like Zork by understanding game state and generating appropriate commands, though it still makes some mistakes and requires careful prompting.
Background
GLM (General Language Model) is a series of large language models developed by Tsinghua University and Zhipu AI, a major Chinese AI company. GLM 5.2 is evaluated on its ability to play classic text-based adventure games (interactive fiction), which tests planning, memory, reasoning, and following long narratives — skills that are weak points for many LLMs. This matters because it gives a concrete, hard benchmark for how far a Chinese frontier model has come, comparable to evaluations of GPT-4, Claude, or DeepSeek. Prior context: GLM has historically lagged behind top Western and some Chinese (e.g., DeepSeek) models, and Zhipu AI has positioned itself as a more cautious, "safe" AI developer in China's regulatory landscape.
