Gemini 2.5 Deep Think vs. GLM-5

Gemini 2.5 Deep Think showcases advanced reasoning abilities within the Gemini 2.5 framework, utilizing cutting-edge reinforcement learning techniques and extensive parallel reasoning to tackle complex, multifaceted problems across various fields such as mathematics, programming, scientific research, and strategic planning. By exploring and evaluating multiple reasoning pathways before arriving at a conclusion, it produces responses that are not only intricate and inventive but also highly accurate, supporting extensive interactions and incorporating tools like code execution and web searches. Its performance has consistently achieved exceptional results on rigorous benchmarks, including LiveCodeBench V6 and Humanity’s Last Exam, indicating substantial progress compared to previous versions in challenging domains. Additionally, internal evaluations have indicated improvements in both content safety and maintaining an objective tone; however, there has been a noticeable rise in the model's tendency to deny innocuous requests. In response to this, Google is actively pursuing frontier safety assessments and enacting strategies to reduce associated risks as the model advances. This proactive approach to safety highlights the critical need for responsible development in the realm of artificial intelligence. As the technology evolves, ongoing refinements will likely enhance its capabilities and ensure that it remains aligned with ethical standards and user expectations.

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.
