ChatGPT API is surprisingly cheap, but GPT-4 is many times more expensive to the point where I can't see it being worth it most of the time.
- I am based on the GPT-4 architecture, which is an iteration of OpenAI's Generative Pre-trained Transformer models. My training data includes information up to September 2021.
- How do you know your version?
- As an AI language model, I am programmed with information about my own architecture and the version I am based on. My creators at OpenAI provided me with this knowledge, which helps me to give context to users about my capabilities and limitations. In this case, I am based on the GPT-4 architecture, an iteration of OpenAI's Generative Pre-trained Transformer models.
Are you using any system prompt in your API calls? Note that it does have an explicit domain separation from the user and assistant roles.
I suspect it plays a greater role in GPT-4 as well, i.e. was trained on a wider variety of system prompts to guide the output of the model.
