# Clover Image Tiny Inpaint HQ

Clover Image Tiny Inpaint HQ is the high-quality, context-aware inpainting
companion to [Clover Image Tiny](https://huggingface.co/neonforestmist/Clover-Image-Tiny).
It combines the complete Stable Diffusion 1.5 inpainting U-Net with Clover
Image Tiny's tokenizer, text encoder, VAE, and scheduler.
This preserves Clover compatibility while replacing the compact inpainting
denoiser that frequently produced blurry or unrecognizable masked objects.

The pipeline uses the standard nine-channel inpainting contract:

```text
[noisy latent (4), mask (1), masked-image latent (4)]
```

## Diffusers example

```python
import torch
from diffusers import AutoPipelineForInpainting, DPMSolverMultistepScheduler
from diffusers.utils import load_image

pipe = AutoPipelineForInpainting.from_pretrained(
    "neonforestmist/Clover-Image-Tiny-Inpaint",
    torch_dtype=torch.float16,
).to("cuda")
pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)

image = pipe(
    prompt="a glossy red enamel kettle resting naturally on the countertop",
    negative_prompt="blurry, distorted, low detail",
    image=load_image("source.png"),
    mask_image=load_image("mask.png"),
    num_inference_steps=20,
    guidance_scale=6.0,
    padding_mask_crop=96,
).images[0]
image.save("clover-inpaint.png")
```

Recommended interactive defaults are DPM-Solver++, 20 steps, CFG 6.0, and a
96-pixel context crop. Composite the generated result through the exact binary
mask when unchanged source pixels must remain byte-for-byte untouched.

## Inpainting example

This edit starts from the Clover Image Tiny artwork below and uses the prompt
`add blue sunglasses`. The source and result are included so the masked edit
can be compared directly.

| Source image | Inpainted result |
|:---:|:---:|
| ![Cat source before adding sunglasses](examples/sunglasses-source.png) | ![Cat after adding blue sunglasses](examples/sunglasses-result.png) |

## Quality gate

The release was evaluated on 24 deterministic, held-out, human-rated
InpaintCOCO edits. Every output was also reviewed in three visual contact
sheets before release.

| Metric | Previous Clover inpaint | HQ release | SD 1.5 inpaint teacher |
|---|---:|---:|---:|
| Masked prompt CLIP similarity (higher) | 0.2642 | **0.2768** | 0.2820 |
| Masked target MAE (lower) | 0.2510 | **0.2231** | 0.2156 |
| Changed pixels outside the mask | 0 | **0** | 0 |

The HQ release improves prompt alignment by 4.8% and reduces masked target
error by 11.1% relative to the previous Clover inpainting release. The visual
gate showed recognizable buses, dogs, trains, furniture, signs, and
scene-consistent lighting where the compact candidates often collapsed into
amorphous fills.

## Selection provenance

The release process compared the existing checkpoint, a 30,000-step full-U-Net
distillation run, two fused context-LoRA refinements, partial weight blends,
the full Stable Diffusion inpainting reference, and this Clover-component
hybrid. The 30,000-step and context-LoRA candidates were rejected because they
did not beat the existing release across both visual and quantitative gates.
The published HQ architecture was the only Clover-compatible candidate that
materially improved both prompt alignment and reconstruction.

## Core ML and style mixing

The companion iOS resources are published at
[`neonforestmist/Clover-Image-Tiny-Inpaint-CoreML`](https://huggingface.co/neonforestmist/Clover-Image-Tiny-Inpaint-CoreML).
Its batch-one stateful U-Net supports up to three Clover styles simultaneously
with independent strengths. The style tensors remain separate downloads and
are composed exactly at runtime; they are not fused into three full 1.6 GB
models.

## Limitations

Small text, hands, faces, exact logos, and masks below latent resolution can
still fail. Output quality depends on the source, mask, prompt, scheduler,
guidance, seed, and step count. This release inherits the limitations and
license obligations of Clover Image Tiny and Stable Diffusion 1.5 inpainting.
