Show HN: Infinity – Realistic AI characters that can speak

Article summary

The authors of Infinity AI have trained a video diffusion transformer model that can generate realistic AI characters that speak, allowing for expressive and realistic-looking characters. The model takes in a single image, audio, and other conditioning signals and outputs video. The authors claim this is the first time someone has trained a video diffusion transformer driven by audio input. The model has been trained for about 11 GPU years and is still actively being trained.

Main themes

• AI-generated video
• Realistic characters
• Audio-driven animation
• Model training
• Pricing and accessibility
• UI design trends

What commenters say

• The company should make the model's weights open-source, at least for older versions, to promote transparency and collaboration.
• The model's ability to generate realistic characters that speak has the potential to revolutionize the entertainment industry, particularly in dubbing and voice acting.
• Requiring users to sign up before using the model is unnecessary and may deter potential users, who may prefer a more open and accessible approach.
• The use of celebrity images without consent in product demos raises legal and ethical concerns, and the company should reconsider its approach to avoid potential lawsuits.
• The current web design trend of using animations and dynamic content is seen as engaging and beautiful by some, but exhausting and distracting by others, who prefer simpler and more static designs.
• The company's decision to use a standard CSS package and UI design is seen as a practical choice, but also criticized for lacking uniqueness and originality.
• The model's limitations, such as its inability to handle animals or cartoons, and its tendency to distort people's identities, are notable and should be addressed in future updates.
• The company's stance on using famous people's images for parody videos is seen as a complex issue, with some arguing it is a form of free speech and others seeing it as a potential infringement on celebrity rights.
