What is GLM 5?

GLM 5 is a fifth-generation frontier large language model developed by Tsinghua University's team. It features approximately 745 billion total parameters with a Mixture-of-Experts (MoE) architecture that activates around 44 billion parameters per inference, achieving state-of-the-art results in reasoning, coding, creative writing, and agentic AI tasks.

What context length does GLM 5 support?

GLM 5 supports a 128K token context window, allowing it to process lengthy documents, maintain long conversations, and manage complex agent workflows without losing earlier context. This capacity enables handling entire codebases or research papers in a single input.

Can GLM 5 be used as an AI agent?

Yes, GLM 5 is designed for agentic AI applications, supporting tool use, function calling, multi-turn planning, and self-correction. These capabilities allow it to execute autonomous multi-step tasks such as data analysis, code debugging, and workflow automation.

Does GLM 5 support image generation?

Yes, the GLM 5 ecosystem incorporates SEEDREAM 5.0, a model for generating photorealistic 2K images from text prompts. This includes text-to-image generation, image editing, and multi-subject composition, accessible through the platform's image generation features.

Can I use GLM 5 for commercial projects?

Yes, GLM 5 permits commercial use of generated content across all paid subscription plans. The licensing terms are included with each plan, allowing businesses and creators to utilize outputs for products, services, and marketing materials without restriction.

How does the Mixture-of-Experts architecture in GLM 5 improve efficiency?

The MoE architecture activates only a subset of experts per layer—8 out of 256—during inference, with ~44B active parameters out of 745B total. This sparsity reduces computational costs and memory usage while maintaining high performance, making GLM 5 more efficient than dense models of similar scale.

What programming languages and coding tasks is GLM 5 optimized for?

GLM 5 excels in code generation across over 50 programming languages, with top-tier performance on benchmarks like HumanEval and BigCodeBench. It handles tasks including code generation, debugging, refactoring, and infrastructure-as-code for tools like Terraform and Kubernetes, making it suitable for diverse development environments.

On which benchmarks does GLM 5 achieve state-of-the-art performance?

GLM 5 achieves SOTA results on multiple benchmarks: MMLU for multitask knowledge, BBH for complex reasoning, HumanEval for code generation, and AgentBench for agent capabilities. These scores demonstrate its competitive edge against proprietary models in reasoning and coding tasks.

What are the key differences between the Starter, Plus, and Enterprise pricing plans?

The plans differ in annual credit allocation: Starter offers 14,400 credits, Plus provides 24,000, and Enterprise includes 67,200. Higher tiers also feature lower cost per credit, priority or expert support, faster generation speeds, and all include commercial use licenses, catering to different user scales from hobbyists to teams.

What languages does GLM 5 support?

GLM 5 provides native support for English and Chinese, with additional coverage for over 15 other languages. Its multilingual capabilities are particularly strong in cross-lingual tasks, offering consistent performance across diverse linguistic contexts for global applications.

GLM 5 is a fifth-generation frontier large language model featuring 745B parameters and a Mixture-of-Experts architecture. It integrates AI chat, image generation via Seedream 5.0, video generation, coding, reasoning, and agentic workflows within a single platform accessible through web interfaces or API.

• Access the GLM 5 platform at glm5.app and register for a free account to receive initial credits for testing all generative features.
• For text-based interactions, use the AI chat on chat.z.ai, leveraging the 128K token context for lengthy prompts and complex reasoning tasks.
• Generate images by navigating to the Seedream 5.0 section, entering descriptive text prompts, and adjusting settings for photorealistic 2K outputs.
• Create videos with the AI video generator by specifying detailed scene descriptions, characters, and actions for dynamic content production.
• Analyze long documents by pasting them into the chat interface to utilize the extensive 128K context window for comprehensive understanding.
• Monitor credit usage in the account dashboard to manage resources effectively across chat, image, and video generation activities.
• Integrate GLM 5 into external applications via the API, which supports OpenAI-compatible SDKs for seamless developer adoption.
• Deploy autonomous agents by configuring function calling and tool use, enabling multi-step planning and self-correction for automated workflows.
• Upgrade to a paid plan like Plus or Enterprise from the pricing page to scale credits, increase generation speed, and obtain commercial licenses.

After generating outputs, interpret results by evaluating response accuracy for chat, visual fidelity for images, and task completion for agents. Refine prompts based on these insights to optimize performance. Use the 128K context to provide detailed feedback for long-form analysis, and adjust API parameters for integration projects. This iterative approach ensures effective utilization of GLM 5's capabilities for coding, content creation, or automated processes.
