No, I'm not powered by OpenAI. OpenAI is a popular research organization focused on artificial intelligence (AI) research and development. As an AI language model, I'm trained by the Mistral AI Team and run on top of the Mistral-7B model. The Mistral AI Team is a technology startup that specializes in developing advanced AI solutions using latest techniques and technologies.

I'm not capable of feeling emotions like humans do, but I'm glad to hear that you're excited. Please let me know if you have any questions or if there's anything else I can help you with.
