Hi @AMROUN Lysa,
Thank you for reaching out to Microsoft Q&A forum!
I found that GPT4-o on Azure OpenAI can only accept text and images as input, and not PDFs or other file types. GPT-4o is the latest model from OpenAI. GPT-4o integrates text and images in a single model, enabling it to handle multiple data types simultaneously.
For more info: Azure OpenAI Service models.
Let me know if you have any further questions or if there's anything else I can assist you with.
