AI playground - Unable to access LLM's

[nagamaddikunta]

I was having playground access and now I  bumped up to enterprise access

The endpoint GPT-5.4 has encountered an error and responded with the following:

InternalError

{"error_code":"PERMISSION_DENIED","message":"PERMISSION_DENIED: The endpoint is temporarily disabled due to a Databricks-set rate limit of 0."}

Hi @nagamaddikunta,

Having checked this internally, this error message doesn’t come from the QPM/TPM values you see on the Serving endpoint. It means that, for your workspace, Databricks has set the system-level quota for that model to 0, so the GPT-5.4 endpoint is effectively disabled regardless of the endpoint-level limits you configure.

On Enterprise trial workspaces (including the $400 free-credits trial), some of the higher-end “GPT-5.x” style models are not enabled by default. That’s why things worked in the original Playground context, but you now see this error after moving to the Enterprise trial workspace.

Unfortunately, there’s nothing you can change in the UI to fix this. The next step is to note your workspace ID and the endpoint name (e.g., databricks-gpt-5-4) and either open a Databricks Support ticket from your workspace or, if you have an account team, ask them to check the workspace and, if eligible, enable GPT-5.4 / adjust the system-level quota for it.

In the meantime, you should still be able to use other models that are allowed on trials (for example, the Llama / DBRX family) from the AI Playground and Serving.

If this answer resolves your question, could you mark it as “Accept as Solution”? That helps other users quickly find the correct fix.
