Frequently asked questions
How do I use GLM 5.3 on Runpod?
Call GLM 5.3 as a Runpod Public Endpoint with your API key. Runpod hosts and scales the model, and you pay per use. You can also deploy the open weights on your own Serverless endpoint.
What GPU do I need to run GLM 5.3?
Start with 8× H200 (1128 GB VRAM). The weights take about 755 GB; longer contexts and more concurrent requests need extra memory for the KV cache.
How much does GLM 5.3 cost on Runpod?
Public Endpoints bill per use at the rates on this page. Serverless endpoints and Pods bill per second for the GPU you choose, with no charge while a Serverless endpoint is scaled to zero.
