Overview

GLM 5 is a fifth-generation frontier large language model developed by Zhipu AI, featuring 745B total parameters with a Mixture-of-Experts architecture that activates ~44B per inference. It delivers state-of-the-art performance in reasoning, coding, creative writing, and agentic AI tasks, with a 200K token context window and multilingual support. This independent platform offers chat, image, and video generation, plus an OpenAI-compatible API, making it suitable for developers, researchers, and content creators. This is an independent third-party service and is not operated by the company behind the model it is built around.

Architecture and performance

GLM 5 uses a Transformer decoder with Mixture-of-Experts, featuring 78 layers, 256 experts per layer with 8 activated, and DeepSeek-style Sparse Attention. It employs Multi-Token Prediction for faster inference, achieving 2x throughput over traditional autoregressive decoding. The model supports a 200K token context window, enabling long-document understanding and complex agent workflows.

Key capabilities

GLM 5 excels in advanced reasoning, code generation across 50+ programming languages, and agentic AI workflows with tool use and function calling. It also supports creative writing with nuanced style control and image generation via Seedream 5.0 for photorealistic 2K output. Video generation is available with models like Seedance and Kling.

Who it is for

GLM 5 is designed for developers, researchers, product teams, and businesses needing strong reasoning, coding, and long-context analysis. It is also useful for content creators generating images and videos, and for teams building AI agents and automation systems. The platform is accessible via browser and API, with no local hardware required.

Pricing and plans

GLM 5 offers flexible credit-based pricing with monthly and yearly plans. Starter costs $9.9/month, Plus $14.9/month, and Enterprise $39.9/month, with yearly plans saving up to 50%. Free credits are available to start without a credit card. Credits are shared across chat, API, image, and video, with one-time packs that never expire.
