Pricing

GLM 5.3 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.

GLM 5.3 bills at the same per-token rates as GLM 5.2. Pricing is flat across the full context window, with no long-context surcharge and no separate cache-write fee.
