       | My theory is that they're using a fine-tuned version of
       | GPT-4-turbo in ChatGPT to fix the issue with everyone saying it
       | was lazy. They fine-tuned it using responses from GPT-4.5-turbo,
       | which they have internally. This synthetic data was probably
       | based on a suite of questions which included self-identification,
       | leading to it releasing its model name in the training data, and
       | the new ChatGPT less lazy model is adopting the name via osmotic
       | data leakage.

       | Chat GPT want to grow?" Cue the Techcrunch articles.

         | It is also about reducing competitors. Like Nuclear Weapons,
         | the first one rules the world. After you had them, you made
         | sure that nobody else will get them. Or at least they did their
         | best.

           | It could be something as mundane as making a portmanteau of
           | "gpt-4" and "gpt-3.5-turbo" to get "gpt-4.5-turbo".

       | people of wrong information based on those hallucinations is not
       | what I dreamed about doing in this industry as a kid and a young
       | adult. I just wanted to make video games and after that I just
       | wanted to use technology to make things more efficient for
       | people. I now wish I would have gone to medical school.
