[czlowieku]

below code baiscly. Usage is set fine when CreateCompletion is used instead.

await foreach (var res in _openAiService.Completions.CreateCompletionAsStream(
completionCreateRequest,_gptConfig.Model,token))
{
if (res.Usage != null)
{
//this is allwayas null
}
if (!string.IsNullOrEmpty(res.Choices.First().Text))
{
//even when this returns something
}
}
