Hi NVIDIA team,

I can call google/gemma-4-31b-it successfully with the same API key and endpoint:

POST https://integrate.api.nvidia.com/v1/chat/completions

But google/diffusiongemma-26b-a4b-it returns:

{
  "status": 404,
  "title": "Not Found",
  "detail": "Function 'ffd13b18-1c55-4a7a-b71a-acbfde9ce8a0': Not found for account '<redacted>'"
}

GET /v1/models does list the model:

{
  "id": "google/diffusiongemma-26b-a4b-it",
  "object": "model",
  "created": 735790403,
  "owned_by": "google"
}

This looks specific to google/diffusiongemma-26b-a4b-it, possibly a backend function deployment / entitlement / catalog-to-function mapping issue.

Could you check whether the hosted endpoint for google/diffusiongemma-26b-a4b-it is currently experiencing a service-side issue?

Yes, I have the same problem. Only that model, others are fine
