+# Pixel Art Sprite LoRA for FLUX.2-klein-4B
+
+A LoRA adapter trained on FLUX.2-klein-4B for generating pixel art character sprites. Optimized for game-ready assets with transparent backgrounds.
+
+## Highlights
+
+- **4-step inference** — FLUX.2-klein is distilled, so generation is fast
+- **512x512 RGBA** output with transparent backgrounds
+- **CC0 training data** — 100% public domain, no copyright concerns
+- **Game-ready** — designed for Godot, Unity, and other engines
+
+## Quick Start
+
+### Trigger Words
+
+Always include in your prompt:
+
+```
+pixel art sprite, [your character description], game asset, transparent background
+```
+
+**Style modifiers:** `16-bit pixel art`, `32-bit pixel art`, `chibi`
+
+### Inference Parameters
+
+| Parameter | Value |
+|-----------|-------|
+| Steps | 4 |
+| CFG Scale | 1.0 |
+| Resolution | 512x512 |
+| Sampler | Euler |
+
+### Python (Diffusers)
+
+> Requires `diffusers >= 0.37.0.dev0` (install from git main)
+
+```python
+import torch
+from diffusers import Flux2KleinPipeline
+
+# Load base model + LoRA
+pipe = Flux2KleinPipeline.from_pretrained(
+    "black-forest-labs/FLUX.2-klein-4B",
+    torch_dtype=torch.bfloat16,
+    low_cpu_mem_usage=False,
+)
+pipe.load_lora_weights("Limbicnation/pixel-art-lora")
+pipe.to("cuda")
+
+image = pipe(
+    "pixel art sprite, a brave knight in shining armor, game asset, transparent background",
+    num_inference_steps=4,
+    guidance_scale=1.0,
+    height=512,
+    width=512,
+).images[0]
+
+image.save("knight.png")
+```
+
+### ComfyUI
+
+1. Download the LoRA weights:
+   ```bash
+   huggingface-cli download Limbicnation/pixel-art-lora \
+       pytorch_lora_weights.safetensors \
+       --local-dir ./models/loras/
+   ```
+2. Load FLUX.2-klein-4B as the base checkpoint
+3. Add a **Load LoRA** node, point to `pytorch_lora_weights.safetensors`
+4. Set LoRA strength: **0.85 - 1.4** (tested range)
+5. Use trigger words in your positive prompt
+
+A sample workflow is included: [`comfyui_workflow.json`](./comfyui_workflow.json)
+
+## Training Details
+
+| Parameter | Value |
+|-----------|-------|
+| Base model | `black-forest-labs/FLUX.2-klein-4B` |
+| LoRA rank | 64 |
+| LoRA alpha | 128 |
+| rsLoRA | Yes |
+| Dtype | bfloat16 |
+| Steps | 1000 |
+| Batch size | 1 |
+| Gradient accumulation | 4 |
+| Learning rate | 1e-4 |
+| LR scheduler | Cosine with restarts |
+| Optimizer | AdamW 8-bit |
+| Resolution | 512x512 |
+| Dataset | 500 images (CC0 curated + synthetic) |
+
+## Architecture Notes
+
+FLUX.2-klein-4B uses a different architecture from FLUX.1:
+
+- **Text encoder:** Qwen3 (not CLIP+T5)
+- **Pipeline class:** `Flux2KleinPipeline` (not `FluxPipeline`)
+- **VAE:** `AutoencoderKLFlux2`
+- **Distilled:** 4-step inference with guidance scale 1.0
