Do not see option Add your data in Azure AI chat playground for DeepSeek model

Issue 1:

I am evaluating different models in Azure AI Foundry against my own data in Azure AI search and do not see option to add your data when DeepSeek-R1 model is selected in chat playground. It used to be there but disappeared recently ( precisely on Feb 18 ET). However see option to add your data when gpt models are selected in chat play ground.

Issue 2:

When add your data option was available for DeepSeek-R1 model (prior to Feb 18,2025), I was getting following error in chat playground "An error occurred when calling Azure OpenAI: Server responded with status 400. Error message: {'error': {'code': 'unknown_model', 'message': 'Unknown model: chatgpt', 'details': 'Unknown model: chatgpt'}}"
