Request: Enable DeepSeek V4 Flash 0731 inference access on my account

Hello,

I have an NVIDIA NIM API key associated with this account. The key authenticates successfully and GET /v1/models returns HTTP 200, but every inference call to POST /v1/chat/completions for deepseek-ai/deepseek-v4-flash-0731 (and other DeepSeek models) returns:

404 Not Found — Function not found for account 'QUdDmEUcG-...'

This indicates my account is not yet enabled for inference on these models. Could you please activate inference access for the DeepSeek family (specifically deepseek-ai/deepseek-v4-flash-0731) on my account, or confirm whether this model is currently restricted/coming soon?

Key prefix: nvapi- Thank you for your help.
