    Hi Pathania, Sandeep [RTL Deutschland], u deployed the o4-mini model in azure ai playground and it’s throwing this "completions call failed" error, right?

    U should check if the deployment actually finished. sometimes azure says it’s done but… not really ) go to the deployments tab in azure openai studio and see if the status is "succeeded". if it’s still "processing", just wait a bit. here’s the microsoft docs on deployments.

    next, make sure u’re using the right endpoint and key. u can find these in the "keys and endpoint" section of ur azure openai resource. copy-paste them into the playground settings. if u messed up even one character, it’ll fail ))

    also, the model might not be available in ur region. o4-mini is kinda new. if not, u gotta switch regions or pick another model.

    if u tried both global and data standard deployments and it still fails, there might be a quota issue. go to the "quotas" section in azure ai studio and see if u hit the limit. sometimes u gotta request more capacity.

    last thing check the activity logs. they’re like a detective tool for azure errors. go to ur resource group, find the "activity log" tab, and look for failed operations. might give u a clue.

    hope this helps )) azure can be a pain, but once it works, it’s smooth sailing. let me know if u’re still stuck!

    Best regards,

    Alex

    Hi Pathania, Sandeep [RTL Deutschland]

    Could you please provide more clarity on this point.

    Actually I am using Model from Germany but for region i have selected swedencentral,

    Does this mean your Azure OpenAI resource is hosted in Sweden central but you have selected Germanywestcentral as deployment region for your GPT-4o-mini model

    In that case, it might fail too as the model supportability is more emphasized on deployment region so deploying a model in sweden central while azure openai base region Germany might work.

    Plus, All Azure OpenAI deployment inherits their resource region from OpenAI base region.

    So, I would suggest you create a Azure OpenAI account in sweden central and create a GPT 4o-mini model

    Requesting to share a screenshot from your side to map the above error if the issue persists,

    Thank you.
