GLM-4.5

GLM-4.5 is an open-source large language model released by Z.ai, formerly known as Zhipu, and made publicly downloadable for free, with its codebase hosted under the zai-org organization on GitHub. The release is positioned by Z.ai as a step forward for open-weight AI, offering enterprise-level capabilities that the developer had previously kept behind proprietary systems. Coverage around its launch framed the model as a cost-conscious alternative to peers such as DeepSeek, reflecting Z.ai's strategy of combining open availability with competitive pricing.

According to third-party descriptions, GLM-4.5 is designed specifically for agentic workflows, advanced reasoning, and software development, making it a practical fit for coding agents, tool-using assistants, and complex task automation. Reportedly, at roughly half the size of DeepSeek's comparable model, it can run on about eight Nvidia H20 chips, which lowers the hardware bar for self-hosting and local experimentation. Combined with its open weights and developer-oriented focus, GLM-4.5 is best suited to teams building agent frameworks, retrieval-augmented pipelines, and reasoning-heavy applications that benefit from a transparent, locally deployable foundation model.
