## Is this contains the real GPT-5 API?

**Question:**

*Why, when I ask the **`GPT-5`** model about its model name, does it answer **`GPT-4`**? instead of **`GPT-5`***

**Answer:**
> The name given to a model is often created after the model has been trained. So, it has no idea what it’s called.
Also, the models do not have a sense of self, they often produce results from the perspective of a human, because that’s what’s in the training data. Ask an AI about AI’s and they will refer to the AIs as outsiders to us humans.
The only way GPT-5 knows what it is, is if you tell it in the system prompt as _j pointed out.
