Question about api-version Parameter and Usage in OpenAI API within SAP Gen AI Hub

[doinnam]

Hello, I am currently developing an AI service using the OpenAI model within the SAP BTP environment, specifically leveraging the SAP Gen AI Hub.

During the process of setting the deployment URL, I noticed the `api-version` parameter. The provided example URL format is as follows:

"/v2/inference/deployments/{my deployment info}/chat/completions?api-version=2023-05-15"

I have a few questions regarding this:

1. What does the `api-version=2023-05-15` parameter signify, and is it safe to change it arbitrarily?

2. Are there any official documents or resources where I can learn more about this parameter?

3. Are there any specific considerations when specifying the API version for OpenAI within SAP BTP?

I am using AI Core and SAP Generative AI Hub to deploy my model and aim to integrate it into an end-to-end service. Properly setting the API version is crucial for this integration.

I would appreciate any insights or guidance on this matter. Thank you!
