# Image comparison gallery

All comparison pictures are actual recorded inference outputs. Each stack
contains labeled full frames, identical 1:1 crops and absolute RGB differences
amplified eight times. Metrics apply to full-resolution images, not previews.

[The editing demonstration](https://huggingface.co/devin-lai/MiniMax-H3-Image-mlx-examples/blob/v0.4.0/comparisons/edit-example/before-after.png) places the input
reference beside the native MLX emerald-glass edit. It is a functional example,
not a pixel-similarity comparison.

The CUDA comparison uses the original saved RTX 5090 BF16 run with upstream
`quality=lossless`. Its hardware and decoder quality setting differ from the
MLX native tile recipe. It provides visual context; it does not isolate port
error or establish a same-hardware speedup.

The default MLX BF16 output is the reference for the quantization/tuning
comparisons. Q8, Q4, fused kernels and fewer steps change its pixels. Read the
[experiment report](../reports/RESULTS.md) before selecting a profile.

Full-resolution Mac outputs and trace tensors are retained locally under
`outputs/suite/` (ignored by Git). Source hashes, configuration, memory and
timing records are exported under `reports/inference/` and each gallery's
`metrics.json`. Original model weights are not included.
