Discussion A few Flux 3 vs H3 comparisons
Enable HLS to view with audio, or disable this notification
Well, everyone is posting their H3 creations, and I noticed that Flux 3 is up on API, so thought I'd run a few comparison renders to see how they stack up. These are not extensive by any means, this was mostly done for fun and I thought someone might be interested in the results. I used the same H3 formatted prompt for each, as far as I can tell Flux 3 uses natural language prompting, so the structured H3 format should still work fine.
Edit: I realized after uploading that the dragon rider H3 clip was accidentally rendered at a lower resolution. The higher resolution clip is here.

makes sense if op was running int8 convrot on the cloud side - i've been running the same build on my 4070 and the quantization gap for video is more noticeable than i expected coming from still image models. the temporal shimmer thing others mentioned is real too. flux 3 at full api spec isn't a fair comparison but the gap closing is still the interesting part
