GLM-5.2 is probably the most powerful text-only open weights LLM
Chinese AI lab Z.ai released GLM-5.2, a 753B parameter text-only open weights LLM under MIT license. It leads the Artificial Analysis Intelligence Index among open models and ranks 2nd on Code Arena WebDev. The model has a 1 million token context window but uses more output tokens per task than peers.
GLM-5.2 offers a powerful open weights alternative for text-only tasks, leading benchmarks and rivaling proprietary models.
