GLM-5 vs. DeepSeek-V4 vs. DeepSeek Coder

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.

DeepSeek-V4 represents a new generation of open large language models focused on scalable reasoning, advanced problem solving, and agentic intelligence. Designed to handle complex analytical tasks, it integrates DeepSeek Sparse Attention (DSA), a long-context attention innovation that significantly lowers computational demands while preserving model quality. This mechanism enables efficient processing of extended inputs without the typical performance trade-offs associated with large context windows. The model is trained using a robust, scalable reinforcement learning pipeline that enhances reasoning depth and real-world task alignment. DeepSeek-V4 further strengthens its agent capabilities through a large-scale task synthesis framework that generates structured reasoning examples and tool-interaction demonstrations for post-training refinement. An updated conversational template introduces enhanced tool-calling logic, enabling smoother integration with external systems and APIs. The optional developer role supports advanced orchestration in multi-agent or workflow-based environments. Its architecture is optimized for both academic research and production-grade deployments requiring long-horizon reasoning. By combining computational efficiency with elite reasoning benchmarks, DeepSeek-V4 competes with leading frontier models while remaining open and extensible. The model is particularly well suited for applications involving autonomous agents, tool-augmented reasoning, and structured decision-making tasks. DeepSeek-V4 demonstrates how open models can achieve cutting-edge performance through architectural innovation and scalable training strategies.
