Just a quick test of the same seed between v48 and HD, with both t5 and gner. I opted not to include flan since all of the results with it were very close to t5. Both encoders are fp16.

Positive: Anime screenshot of the Pokemon Horizons series. The subject is Meowscarada the Pokemon. He is looking at the viewer with a smug expression. Outdoors at midday.

Negative: Low Quality. Worst quality.

Cfg: 4, Euler+beta at 26 steps.

I opted not to include flan since the results were almost identical to t5, but slightly worse. Gner produces different enough outputs I think its worth keeping for variety.

HD is confused by the stylized anatomy, and the t5 HD example shows that blurring effect that plagued v50 as well.
