GLM‑4.5 is the latest flagship from Zhipu AI, designed to compete directly with Western-developed open LLMs. The model improves upon GLM‑4, with enhancements in multilingual comprehension, mathematical reasoning, and general task performance. Zhipu claims it now ranks among the best open-access LLMs, and it is freely available through the zai‑org/GLM‑4.5 repository on Hugging Face.

The release adds momentum to a trend of Chinese labs accelerating open model development. For developers building in Chinese or multilingual environments, GLM‑4.5 offers a high-performance, community-accessible option that rivals Meta’s LLaMA or Mistral’s models. For China’s AI ecosystem, this launch signals a stronger claim in the open-source LLM race, both in performance and visibility.

Zhipu AI’s strategy mirrors broader efforts in China to reduce reliance on foreign models while contributing to the global research commons. If GLM‑4.5’s benchmarks hold up under wider adoption, it could mark a step toward greater balance in the global open-source LLM landscape.
