# What does this PR do?
OpenAI Chat Completions supports passing a base64 encoded PDF file to a
model, but Llama Stack currently does not allow for this behavior. This
PR extends our implementation of the OpenAI API spec to change that.

Closes #2129

## Test Plan
A new functional test has been added to test the validity of such a
request
