What Is GLM 5 AI?
GLM 5 AI is a fifth-generation frontier large language model featuring 745B total parameters, Mixture-of-Experts architecture with 44B activated parameters, and 128K context window — delivering open-source SOTA performance across reasoning, coding, and agentic tasks.
GLM 5 AI Architecture: MoE with 745B Parameters
GLM 5 AI uses a Transformer decoder with Mixture-of-Experts (MoE) structure — 78 layers, 256 experts per layer with 8 activated, yielding ~44B active parameters at 5.9% sparsity. The first three layers are dense; subsequent layers use DeepSeek-style Sparse Attention (DSA).
GLM 5 AI Advanced Reasoning & Coding
GLM 5 AI achieves state-of-the-art scores on MMLU, BBH, HumanEval, and AgentBench. Its agentic reasoning pipeline and code generation capabilities compete with Claude Opus 4.5 and GPT-class models — making it the open-source coding and agent SOTA.
GLM 5 AI 128K Context & Multi-Language Support
GLM 5 AI supports a 128K token context window for long-document understanding, multi-turn dialogue, and complex agent workflows. Native support for English, Chinese, and 15+ additional languages with leading multilingual performance.
GLM 5 AI Multi-Token Prediction (MTP)
GLM 5 AI employs Multi-Token Prediction for faster inference — predicting multiple tokens per forward pass, reducing latency while maintaining output quality. Combined with DSA, this delivers 2x throughput over traditional autoregressive decoding.
GLM 5 Key Features and Capabilities
GLM 5 delivers frontier-level performance across reasoning, coding, creative writing, and agentic AI — rivaling the best proprietary models.
Advanced Reasoning
GLM 5 excels at multi-step logical reasoning, mathematical problem-solving, and complex analytical tasks with chain-of-thought capability.
Agentic AI Workflows
GLM 5 powers autonomous agent pipelines — tool use, function calling, multi-turn planning, and self-correction for complex real-world tasks.
Code Generation
State-of-the-art coding performance on HumanEval and BigCodeBench. GLM 5 generates, debugs, and refactors code across 50+ programming languages.
Creative Writing
GLM 5 produces high-quality long-form content, marketing copy, technical documentation, and creative fiction with nuanced style control.
128K Context Window
Process entire codebases, research papers, and legal documents in a single prompt. GLM 5's 128K context enables true long-document understanding.
Image Generation
GLM 5 ecosystem includes Seedream 5.0 for photorealistic 2K image generation — text-to-image, image editing, and multi-subject composition.

What Users Say About GLM 5
Developers, researchers, and teams worldwide trust GLM 5 for production-grade AI tasks.
Jordan Vance
“GLM 5's coding capability rivals the best. My code review and generation pipeline runs 3x faster with the 128K context window.”
Alex Romero
“We use GLM 5 agents to automate our CI/CD pipeline debugging. It reads logs, identifies root causes, and suggests fixes — saving our team 10+ hours per week.”
Emma Collins
“We run user interview analysis through GLM 5 — it synthesizes hundreds of transcripts into actionable insights with themes I'd have missed manually.”
Mei Zhang
“The multilingual capability is genuinely impressive. GLM 5 handles Chinese-English cross-lingual tasks better than any model I've benchmarked.”
