I'm not aware of any specific information about an AI 8.0 download、There are many AI models and software available, and without more context, it's difficult for me to provide a specific answer.

However, I can suggest a few possibilities:

1、Adobe Illustrator: If you're looking for Adobe Illustrator 8.0, I found that it was released in 2001 and is a vector graphics editor、You can try searching for it on Adobe's website or other software download platforms、Keep in mind that older versions of software may not be compatible with newer operating systems or devices.
2、AI chatbot or virtual assistant: If you're looking for a conversational AI model, there are many options available, such as:
* Google Assistant (available on Google Play Store or Apple App Store)
* Microsoft Bot Framework (a set of tools for building conversational AI models)
* Rasa (an opensource conversational AI platform)
3、Machine learning or deep learning frameworks: If you're interested in AI development, you might be looking for frameworks like:
* TensorFlow (available on GitHub or TensorFlow website)
* PyTorch (available on GitHub or PyTorch website)
* Keras (available on GitHub or Keras website)

Could you please provide more context or clarify which AI 8.0 you're referring to? I'll do my best to help.
