| # 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. |
