Chinese startup Z.ai, formerly known as Zhipu AI, has unveiled GLM-5.2, a large language model (LLM) designed for "long-horizon" autonomous coding and engineering tasks.Long-horizon tasks are projects that require an AI system to plan ahead, retain context, and complete many connected steps over an extended period, rather than carrying out a single action.According to Ollama, which hosts Z.ai's flagship AI models, including the GLM-5 series, the model is built to handle large-scale software development work."With a truly usable 1M-token context window, it can handle project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and complete the…
