Chinese AI lab Zhipu AI releases GLM-5.2 with a stable 1-million-token context under the MIT license. On FrontierSWE, a benchmark for hours-long coding tasks, the open-source model trails Anthropic's Claude Opus 4.8 by just one percentage point. On reasoning, it still falls well behind closed-source rivals.

GLM-5.2 ships 744B params under MIT license. Here's the hardware you need, the quant that fits, and the setup for llama.cpp, Ollama, and LM Studio.

Z.ai released GLM-5.2 with a usable 1-million-token context window across all GLM Coding Plan tiers; MIT weights pending.
