ChatGPT (at least in Plus) when using the GPT-4 model selected (instead of GPT-3.5) currently consistently reports the April 2023 knowledge cutoff of GPT-4-Turbo (gpt-4-1106-preview/gpt-4-vision-preview) as its knowledge cutoff, not the Sep 2021 cutoff for gpt-4-0613, the most recent pre-turbo GPT-4 model release.
The most sensible explanation is that ChatGPT is using GPT-4-Turbo as its GPT-4 model.
