+QWEN-IMAGE 2512 — FP4 PTQ QUALITY EVALUATION
+================================================================================
+
+Configuration:
+  Baseline: BF16 (no quantization)
+  Latent shape: (1, 4096, 64)
+  Image size: (1024, 1024, 3)
+  Prompt: 'a photo of an astronaut riding a horse on mars, highly detailed, 4k'
+  Seed: 42, Steps: 30, Size: 1024x1024
+
+LATENT-SPACE METRICS (on raw denoised output before VAE decode):
+  Latent MSE  = Mean Squared Error (lower = better, 0 = identical)
+  CosSim      = Cosine Similarity (1.0 = identical direction)
+  SNR         = Signal-to-Noise Ratio in dB (higher = better)
+
+IMAGE-SPACE METRICS (on decoded 1024x1024 images):
+  Img PSNR    = Peak Signal-to-Noise Ratio in dB (higher = better)
+  SSIM        = Structural Similarity Index (1.0 = identical)
+  LPIPS       = Learned Perceptual Similarity (lower = better)
