The version of the model (e.g. '0125' for 'gpt-3.5-0125').
Azure OpenAI doesn't return model version with the response by default so it must be manually specified if you want to use this information downstream, e.g. when calculating costs.
When you specify the version, it will be appended to the model name in the response. Setting correct version will help you to calculate the cost properly. Model version is not validated, so make sure you set it correctly to get the correct cost.
