ChatGPT is the only bot that reliably cites sources (through Web search mode).

The other bots either make up links or simply don't provide any information that is distinguishable from the LLM predictive output.

Ironically Gemini is also very bad at this, while it should have been the best at Web search.

Gemini also does something very patchy, which is to provide "links" which are in fact GET queries into classic Google search. I'm guessing they did it this way because the links generated/hallucinated by the LLM were too unreliable.
