ComfyUI Infinite Talk— One-Click Installer - Nvidia 50XX Series Compatible — Patron Supporter Exclusive 🎁 (Patreon)

Hi Friends,

Like with my other Video here is a super simple — no hassle, confusion free setup that works out of the box. And the best part? It should run smoothly even on older GPUs. If not, don’t worry — just send me a message and I’ll help you out!

1. Download Python 3.13 🐍

https://www.python.org/downloads/release/python-3137/

2. Get Git

If you haven’t already, install Git from here:

https://git-scm.com/

🧪 3. Check Git Version

Make sure it’s installed properly:

git –version

🏃‍♂️‍➡️ 4. Run the bat file Installer Script. My 🎁 to you :)

The Download can take quite a while... because its up to 50 GB in size.

💬 If you run into any issues, just send me a direct message and include your .log so I can help out faster.

💡 What About Sage Attention?

I invested around 30 hours creating this installer to ensure a smooth, no-hassle setup. During testing, I also attempted to integrate Sage Attention. However, Sage Attention is not yet compatible with Python 3.13, which this installer is based on.

To work around this, I’ve prepared a dedicated model-only downloader. You can combine the installers as follows:

1. Run the Sage Attention installer first and the Update.bat

2. Afterwards, execute the infinite-talk_model-standalone-downloader bat from the same folder.

3. Finally, install any missing nodes via the Manager.

This way, you still get a clean setup while keeping compatibility intact.

Best,
Chris
