glm-5.1

GLM-5.1 is the next-generation flagship model launched by Zhipu AI, specifically designed to tackle “long-term, complex engineering tasks.” GLM-5.1 boasts exceptional self-correcting and long-term optimization capabilities, enabling it to maintain high productivity across hundreds of iterations and thousands of tool calls. Whether it’s generating intricate codebases, optimizing underlying core logic, or managing autonomous development workflows lasting several hours, GLM-5.1 demonstrates judgment and execution skills that closely resemble those of human experts.───────────────────────────────────────────────────────────────────

Core Capabilities

Peak Performance in Long-Term Engineering Tasks: Achieving state-of-the-art (SOTA) performance on key engineering benchmarks such as SWE-Bench Pro, demonstrating its outstanding ability to handle large-scale, unstructured codebase tasks.

Continuous Optimization and Iterative Architecture: Equipped with powerful “repeated iteration and strategy refinement” capabilities, GLM-5.1 not only maintains—rather, continually improves—output quality as the number of tool calls increases, steadily approaching the optimal solution through continuous experimentation and self-calibration.

A “Doer” for Complex System Engineering: Supports continuous autonomous work for more than 8 hours, capable of independently completing the entire workflow—from architectural design and environment configuration to functional implementation. It excels particularly in subjective tasks like web application development, where explicit metrics are lacking.

Deep Integration with the Agentic Coding Ecosystem: Natively compatible with mainstream development workflows such as Claude Code and OpenClaw, making it the preferred model within the coding agent community and delivering developers a genuine boost in productivity.</
