The model `…` does not exist or you do not have access to it
The model name is wrong, deprecated, or your account/key doesn’t have access to it. Check the exact model id, your access, and that you’re calling the right endpoint and base URL.
On Standard Compute the model is always just “standardcompute” — a single id that routes to the best available frontier model. You never chase renamed or deprecated model names. Set the base URL to https://api.stdcmpt.com/v1 and you’re done.
Providers deprecate and rename models regularly. A name that worked last month can 404 today. Pinning to a single routed identifier avoids the churn.
