Quick overview
- The test ran on a rented A100 80GB at $1.79 an hour: full precision, 40 steps, 720p, no shortcuts.
- Each step took 127 seconds, which is 30 minutes of compute for 1 second of video.
- A 10-minute video would take 12 days and cost around $500. HeyGen costs about $20.
- $500 Cost of one 10-minute video
- 30 min Compute per second of video

The test
Can open source AI get close to paid avatar quality for less? The test used a rented A100 with 80GB at $1.79 an hour, full precision, 40 steps and 720p. Every step took 127 seconds.
The cost
That is 30 minutes of compute for 1 second of video. A 10-minute video would take 12 days and cost around $500, while HeyGen costs about $20. That is where the experiment stopped.
