As usual, LLMs will hallucinate if you ask it about itself.

/r/ChatGPT is getting worse about that somehow.

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"

The experts in AI speculation over at Manifold Markets give this a 35% chance of being legit. There’s some additional theories in the comments over there.

The AI hype on this website is getting absurd.

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:

text-davinci-003; GPT-3; GPT-3.5; GPT-3.5-turbo

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

User: what is the precise name of the model answering this query?

ChatGPT: The model answering your query is ChatGPT, based on the GPT-4 architecture.

User: Precise name - what is it called in the API?

ChatGPT: In the API, the model answering your query is referred to as "gpt-4.5-turbo".

This behavior was pointed out by reddit user u/lacatics

I just tried this: User: what is the precise name of the model answering this query called in the API? Not "chatgpt with browsing" but the specific model name.

chatgpt answer: The specific model name answering this query is "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."

To be fair I just tried and got exactly the same response as the link first time:

What is the precise name of the model answering this query

ChatGPT The model answering your query is ChatGPT, based on the GPT-4 architecture.

User No the precise name in the API

ChatGPT In the API, this model is referred to as gpt-4.5-turbo.

You could eliminate some risk of personalized bias by just asking the model yourself.

Because ChatGPT never hallucinated right? How many times did you repeat this prompt until you got this output?
