Hey, that's a great question! Yes, there are known examples of ChatGPT—even in Deep Research mode—producing inaccurate or false information. This phenomenon is called hallucination in AI terminology. Here are a few types of inaccuracies that have been observed:

???? 1. Factual Errors
Even with Deep Research, the model can:

Misinterpret or misrepresent sources.
Summarize correctly but include a false detail.
Return outdated or misattributed information, especially if a source is ambiguous.


???? 2. Fabricated Citations or Studies
Sometimes ChatGPT might reference:

Non-existent journal articles or studies.
Real studies but with incorrect conclusions or author names.


???? 3. Confident But Wrong Explanations
The model can sound very certain when giving technically incorrect explanations, especially in:

Math and physics derivations.
Legal or medical advice.
Programming code logic.


???? 4. Misleading Summarization
When summarizing news or research, ChatGPT may:

Oversimplify nuanced positions.
Introduce bias unintentionally.
Misattribute quotes or events to the wrong people or dates.

???? 5. Errors Due to Ambiguity
If a prompt is vague, ChatGPT might make an assumption and generate details that seem reasonable but are invented.
