Thanks for the question, If you want to use OpenAI models to do question answering\completions on your custom data text files, this limit applies to how many data files you can upload and the total size of the files. There is an upload limit, and there are some caveats about document structure and how it might affect the quality of responses from the model. Azure AI Studio and Azure AI Search are two separate services with different capabilities and limitations. The 16MB file size limit you mentioned refers to the maximum size of files that can be uploaded directly to Azure AI Studio. This limit is in place to ensure efficient processing and to optimize the user experience.
On the other hand, Azure AI Search allows you to index data from various sources, including Azure Blob Storage. When using Azure Blob Storage as a data source, the file size limit for individual PDF files is 25MB. This limit is specific to Azure AI Search and is separate from the file size limit for uploads in Azure AI Studio.
In summary, the file size limits for Azure AI Studio and Azure AI Search are different because they are separate services with different capabilities and limitations.
