GLM 5.3 Flash is an open-weight model from Z.ai. Cursor serves it through our inference partners. Learn more about where models are hosted or see the full list of sub-processors.
Pricing¶
GLM 5.3 Flash is a third-party model, so it isn’t part of the usage included with Cursor plans. On The X Subscription it’s billed at the rates below from your prepaid credit. On legacy Cursor plans it draws from the Other Models pool. All prices are per million tokens.
Pricing is flat across the full context window, with no long-context surcharge and no separate cache-write fee.
