Zhipu Open Source's next-generation flagship model, GLM-5.1

Zhipu's flagship open-source model, GLM-5.1, is the world's most powerful open-source model, capable of working independently for over 8 hours and autonomously completing complex engineering tasks. Its code capabilities rank third globally and first among domestic models in benchmark tests such as SWE-Bench Pro, surpassing GPT-5.4 and Claude Opus 4.6. Real-world testing shows it can build a complete Linux desktop system in 8 hours, optimize vector database performance by nearly 7 times, and achieve a 3.6x speedup in ML workloads through 24-hour iterative optimization.
