GLM-5.1

GLM-5.1 is a next-generation flagship model for agentic engineering with significantly stronger coding capabilities. It achieves state-of-the-art performance on SWE-Bench Pro and excels at repo generation and real-world terminal tasks. Unlike previous models that plateau quickly, GLM-5.1 sustains optimization over hundreds of rounds and thousands of tool calls.
