What it costs
An agent resends a long prompt on every turn, so the cached input price matters as much as the input price. GLM 5.3 caches the repeated part of the prompt on its own: from the second turn of a task it is billed at the cached input price.

Frequently asked questions
Does GLM 5.3 work with Zoo Code’s tools?
Yes. It was tested on October 18, 2026 with Zoo Code 3.90.0: tool calls, streaming, reasoning effort and prompt caching.
How much does GLM 5.3 cost in Zoo Code?
Every request Zoo Code makes is billed at the model’s price: $1.19 / $3.74 per 1M input / output tokens. The repeated part of a long prompt is billed at $0.26 per 1M cached input tokens. Each request’s charge is in the console under Logs.
Where do I put my OceanToken key?
Create a key in the OceanToken console and give it a credit limit: an agent sends many requests, and the limit caps what this key can spend. Keep it in an environment variable, never in a file in your repository.
