Granite Code vs. GLM-5

Introducing the Granite series of decoder-only code models, purpose-built for various code generation tasks such as debugging, explaining code, and creating documentation, while supporting an impressive range of 116 programming languages. A comprehensive evaluation of the Granite Code model family across multiple tasks demonstrates that these models consistently outperform other open-source code language models currently available, establishing their superiority in the field. One of the key advantages of the Granite Code models is their versatility: they achieve competitive or leading results in numerous code-related activities, including code generation, explanation, debugging, editing, and translation, thereby highlighting their ability to effectively tackle a diverse set of coding challenges. Furthermore, their adaptability equips them to excel in both straightforward and intricate coding situations, making them a valuable asset for developers. In addition, all models within the Granite series are created using data that adheres to licensing standards and follows IBM's AI Ethics guidelines, ensuring their reliability and integrity for enterprise-level applications. This commitment to ethical practices reinforces the models' position as trustworthy tools for professionals in the coding landscape.

GLM-5 is Z.ai’s most advanced open-source model to date, purpose-built for complex systems engineering, long-horizon planning, and autonomous agent workflows. Building on the foundation of GLM-4.5, it dramatically scales both total parameters and pre-training data while increasing active parameter efficiency. The integration of DeepSeek Sparse Attention allows GLM-5 to maintain strong long-context reasoning capabilities while reducing deployment costs. To improve post-training performance, Z.ai developed slime, an asynchronous reinforcement learning infrastructure that significantly boosts training throughput and iteration speed. As a result, GLM-5 achieves top-tier performance among open-source models across reasoning, coding, and general agent benchmarks. It demonstrates exceptional strength in long-term operational simulations, including leading results on Vending Bench 2, where it manages a year-long simulated business with strong financial outcomes. In coding evaluations such as SWE-bench and Terminal-Bench 2.0, GLM-5 delivers competitive results that narrow the gap with proprietary frontier systems. The model is fully open-sourced under the MIT License and available through Hugging Face, ModelScope, and Z.ai’s developer platforms. Developers can deploy GLM-5 locally using inference frameworks like vLLM and SGLang, including support for non-NVIDIA hardware through optimization and quantization techniques. Through Z.ai, users can access both Chat Mode for fast interactions and Agent Mode for tool-augmented, multi-step task execution. GLM-5 also enables structured document generation, producing ready-to-use .docx, .pdf, and .xlsx files for business and academic workflows. With compatibility across coding agents and cross-application automation frameworks, GLM-5 moves foundation models from conversational assistants toward full-scale work engines.
