HF PRO subscription for large model

I am running the following space: chat-ui - a Hugging Face Space by Cosmic-DNA.
Despite the fact that I just enabled PRO subscription, when interacting with the bot the following message is thrown:

The model h2oai/h2ogpt-gm-oasst1-en-2048-falcon-40b-v1 is too large to be loaded automatically (165GB > 10GB). For commercial use please use PRO spaces or Inference Endpoints.
