ostris trains H3 image VAE overnight with face-identity and OCR losses, benchmark vs MiniMax

ostrisai · x · 2026-11-13

Indie developer ostris shared an overnight fine-tune of the H3 image decoder, adding facial identity and OCR losses on top of lpips, fft, and l1 losses, without a critic loss.

The attached benchmark shows his P-H3-Image VAE (32:1 compression, 26.2M params) still ranking first on MSE/PSNR/SSIM/LPIPS, ahead of Ostris H3 Image VAE and MiniMax-H3-Image — though he notes it's a significantly larger decoder. Training continues.
