Free GLM API Models with $0 Input & Output via Z.ai

Offer Details
Completely free API models
Z.ai’s current official pricing lists GLM-4.7-Flash, GLM-4.5-Flash, and GLM-4.6V-Flash as free for input, cached input, cached-input storage, and output.
GLM-4.7-Flash and GLM-4.5-Flash are text models, while GLM-4.6V-Flash accepts video, image, text, and file inputs.
This is actual $0 model pricing rather than a one-time credit.
However, “free” should not be read as unlimited: Z.ai documents API rate-limit and daily-limit errors, while a fixed universal quota for these specific free models could not be verified.
How to Claim this Deal
- Register or sign in through the Z.ai API Platform (z.ai).
- Open API Keys (z.ai) and create an API key. Z.ai’s quick-start guide says account funding is only needed “if needed.”
- Follow the API Quick Start (docs.z.ai) and use Z.ai’s general API endpoint with a free model such as glm-4.7-flash, glm-4.5-flash, or glm-4.6v-flash.
- Check the current Z.ai pricing page (docs.z.ai) before production use, since model availability and pricing can change.
