Frequently asked questions
What Z.ai models can I run on ModelRunner?
The catalog has 1 public Z.ai model: GLM-5.2. It covers text-to-text. It has its own page with a free playground, the full input schema, and copy-paste code.
How much do Z.ai models cost?
Pay-per-use, with no subscription: the one Z.ai model billed per 1M cached input tokens costs $0.35, and every page publishes its own rate — some are tiered, so a lower resolution or a shorter clip costs less per run. You buy credits and pay only for what you generate.
How do I call a Z.ai model from the API?
POST to https://queue.modelrunner.run/z-ai/glm-5.2 with an Authorization: Key header and the input fields as the top-level JSON body (no wrapper object), then poll the returned status_url and fetch the result from response_url. The JavaScript SDK (@modelrunner/client) wraps that in a single subscribe() call, which is the one place an { input } object is used.
Can I run Z.ai model from Claude or Cursor?
Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and Z.ai's model becomes a tool your assistant can call with run_model — authorized over OAuth 2.1, so no API key goes into a config file. Results come back as hosted URLs in the conversation.
Where is the source code or paper for Z.ai models?
1 of the 1 Z.ai model in the catalog link their own upstream sources — GLM-5.2 — covering some combination of code repository, paper, weights and licence. The links are listed on this page and on each model's own page.
