As an AI language model, my knowledge cutoff is in September 2021, and I don’t have information about specific advancements or developments that may have occurred since then. Therefore, I cannot provide information on the specific capabilities of GPT-4 or any other future versions.

However, it is important to note that GPT models, including GPT-3, are primarily designed for text-based tasks, such as generating coherent and contextually relevant responses to prompts. While GPT-3 can be used for certain forms of media generation, such as text-based storytelling or poetry, it does not have built-in capabilities for generating AI video or other multimedia content.

Advancements in AI technology are continually being made, and it’s possible that future iterations or entirely new models may be developed with improved multimedia generation capabilities. However, without specific information about GPT-4 or any recent announcements or research papers, I cannot confirm or provide details regarding its abilities. It’s always best to refer to the official sources or updated research for the latest information on AI models and their capabilities.
