Kompact and “ Voice / Face Animation” on www.HemenParekh.ai

 


 

Dear Chetanbhai :

 

Sub : Kompact and “ Voice / Face Animation” on www.HemenParekh.ai

 

In Feb 2024 , we chatted about animating my face ( with lip-sync ) on

www.HemenParekh.ai


I reproduce a portion of our chat below at ( A )

This required using a GPU server and as drafted by you , my colleague Sandeep

 sent email to Big Rock Team , shown below at ( B )


Unfortunately, price for use of GPU-based service, came out to around $ 1040

 per month.


I gave up this project since this price was unaffordable


Today, I just came across a news report re; IIT-Madras team having launched “

 Kompact “ innovation , which enables LLMs to run on a standard CPU !  No need

 for a GPU  ! . Read this at ( C ) below


Question:

By using KOMPACT, can we manage that “ Animation “ on Big Rock  ( current CPU-

based configuration ) ?

 


( A )  Extract from my past chat with ChatGPT ( 10 Feb 2024 )  :


I said:

Hey , thanks for your encouraging words and how this might become possible . It is heartening that my Virtual Avatar would be able to establish with each visitor , a unique relationship . Even at this moment ( for past 2 years ) , my Avater V 1.o ( www.HemenParekh.ai ) is able to " speak ( although, in a synthetic voice ) in 26 languages but I am told , animating my photo on my site to lip-sync and speak in my own voice, would be quite expensive. Can you suggest a free or a cheap method to achieve this ?

ChatGPT said:

You're already ahead of the curve with HemenParekh.ai V1.0 speaking in 26

 languages! 


The next logical step—lip-syncing animation with your own voice—can

 be achieved using some low-cost or even free AI tools.

Hello Hemenbhai,

It's great to reconnect with you! I understand your interest in animating your

 avatar's face with lip-sync on www.HemenParekh.ai, and the challenges you've

 faced due to the high costs associated with GPU-based services.

​

The recent development of Kompact AI by IIT Madras and Ziroh Labs is indeed

 promising. This platform aims to run large AI models efficiently on standard

 CPUs, potentially reducing the reliance on expensive GPUs. ​Tech in

 Asia+8Hindustan Times+8LinkedIn+8Tech in Asia+3The Tech Portal+3Hindustan Times+3


However, it's important to note that while Kompact AI shows potential in making

 AI more accessible, there have been critiques regarding the novelty and

 practicality of its achievements. Some in the tech community have replicated

 similar performance using existing tools, suggesting that the claimed

 breakthroughs may not be as groundbreaking as presented. ​Medium+1Medium+1



Regarding your specific application—animating your avatar's face with lip-sync

—the feasibility of using Kompact AI depends on several factors:


  1. Model Compatibility: 

  3. Kompact AI has optimized certain models to run on CPUs. If your animation tools can leverage these models, integration might be possible.​The Indian Express+2LinkedIn+2Analytics India Magazine+2

  1. Performance Requirements: 

  3. Real-time face animation with lip-sync is computationally intensive. While Kompact AI aims to run models on CPUs, achieving smooth, real-time animation without GPUs may still be challenging.​Medium+6TICE News+6Analytics India Magazine+6

  1. Integration Complexity: 

  3. Adapting your existing setup to work with Kompact AI would require technical adjustments. The ease of this integration would depend on the flexibility of your current system and the support provided by Kompact AI.
  4. ​

Given these considerations, while Kompact AI offers an exciting avenue to explore, it may not fully meet the performance needs for high-quality, real-time avatar animation without further optimization or support.


Alternative Approaches:


  • Pre-rendered Animations: 

  • Instead of real-time animation, consider generating pre-rendered videos of your avatar speaking common phrases. These can be triggered based on user interactions, reducing computational demands.
  • ​
  • Hybrid Systems: 

  • Use CPU-based processing for less intensive tasks and reserve GPU resources for demanding processes. This approach balances performance and cost.
  • ​
  • Cloud-based Services: 

  • Some platforms offer pay-per-use models for avatar animation. This can be more cost-effective than maintaining dedicated GPU infrastructure.
  • ​

If you'd like, I can assist in evaluating these alternatives or provide more detailed guidance on integrating Kompact AI into your project. Let me know how you'd like to proceed!
