Possible but it's behavior when asked this question appears consistent and it coincides with an anecdotal reporting of increased performance and the Jimmy Apples "leak" reporting December 14th as the release date for this exact model, "gpt-4.5-turbo"
This proves nothing; note "This conversation may reflect the link creator’s personalized data, which isn’t shared and can meaningfully change how the model responds."

Did you try refreshing that last generation multiple times? Using free ChatGPT with the model displayed at the top of the page being GPT-3.5, it returns any of the following:

Clearly, only one of these can be right, and 1 is not a 3.5 type model at all.

chatgpt answer:
The specific model name answering this query is "gpt-4.5-turbo".
