Z.ai / GLM Changelog
2026-06
GLM-5.2 released
Released June 17, 2026. Zhipu AI open-sourced GLM-5.2, its latest flagship model. The company emphasized long-text capabilities as a breakthrough area. Early published benchmarks show it trailing Anthropic's Claude Opus 4.8 on some coding tasks, though stock-market reaction suggested investor optimism.
Open-weight availability
GLM-5.2 is available as open weights, making it self-hostable and fine-tunable. This continues Zhipu's strategy of releasing competitive open models alongside its Z.ai API platform.
2026-04
GLM-5.1
GLM-5.1 arrived in April 2026 as a mid-cycle upgrade with improved reasoning and instruction following.
2026-02
GLM-5
The GLM-5 series launched in February 2026, moving Zhipu closer to the top-tier model conversation alongside DeepSeek, Qwen, and Kimi.
What this means for users
Z.ai / GLM is a strong option if you need a Chinese-language-capable model, want open weights, or are price-sensitive relative to US providers. As always, verify on your own workloads rather than relying solely on vendor-published numbers.
What to watch
- Independent evaluations of GLM-5.2 long-context and coding performance.
- Community fine-tunes and quantization recipes.
- Z.ai API pricing and availability outside mainland China.
