Perplexity with Titled Citations and Thinking

"""
title: Perplexity with Titled Citations and Thinking
version: 0.2.0
license: MIT

Includes all 5 Sonar models from Perplexity.

Deep Research does not return citations. 
I'm not sure why, and there's very little documentation from Perplexity to help figure it out.

Chats from the other Sonar models will include citations at the end.
Citations will be linked and include the page title, so they look nice.
