Product Positioning

What makes it different

One entry point for GLM models and agents: chat for end-users and an API platform for builders spanning text, image, video and task agents.

Primary use case

Use GLM models via chat or API to build apps, automate work, and generate text/images/video with agentic tools.

Core problem it solves

Teams need reliable, costed access to strong models and agent utilities without stitching together many vendors and pricing systems.
