Is chat gpt has answer of everything?

No, OpenAI's GPT-3 language model is a highly advanced AI model that has been trained on a large corpus of text, but it is not capable of answering every possible question or providing information on every topic. While it has a vast knowledge base and can generate human-like text, it is not perfect and can make mistakes or provide incorrect information. Additionally, the model has a limited understanding of the world, and there may be some questions or topics that it simply does not have enough information to answer accurately.
