# PokéPixels1-9M (CPU)

+
|
| 21 |
+
A minimal diffusion model trained **from scratch on CPU**.
|
| 22 |
+
|
| 23 |
+
This project explores the lower limits of diffusion models:
|
| 24 |
+
**How small and simple can a diffusion model be while still producing recognizable images?**

## 🧠 Overview
|
| 29 |
+
|
| 30 |
+
TinyPokemonDiffusion is a lightweight DDPM-based generative model trained on Pokémon images.
|
| 31 |
+
|
| 32 |
+
Despite its small size and CPU-only training, the model learns:
|
| 33 |
+
- Color distributions
|
| 34 |
+
- Basic shapes
|
| 35 |
+
- Early-stage object structure
|

## 🖼️ Results
|
| 64 |
+
|
| 65 |
+
The model generates:
|
| 66 |
+
|
| 67 |
+
- Coherent color palettes
|
| 68 |
+
- Recognizable Pokémon-like silhouettes
|
| 69 |
+
- Early-stage structure formation
|
| 70 |
+
|
| 71 |
+
Limitations:
|
| 72 |
+
- Blurry outputs
|
| 73 |
+
- Weak spatial consistency
|
| 74 |
+
- No semantic understanding

## 🚀 Usage
|
| 79 |
+
|
| 80 |
+
### Generate images
|
| 81 |
+
|
| 82 |
+
```bash
|
| 83 |
+
python generate.py \
|
| 84 |
+
--checkpoint model.pt \
|
| 85 |
+
--n_images 8 \
|
| 86 |
+
--steps 50 \
|
| 87 |
+
--seed 42
|
| 88 |
+
📁 Output
|
| 89 |
+
|
| 90 |
+
Generated images are saved as a horizontal grid:

>> ⚠️ Limitations
|
| 95 |
+
|
| 96 |
+
Unconditional model (no prompts)
|
| 97 |
+
|
| 98 |
+
Limited dataset diversity
|
| 99 |
+
Early training stage
|
| 100 |
+
No DDIM (yet)

>> 🔬 Research Direction
|
| 103 |
+
|
| 104 |
+
This project demonstrates that:
|
| 105 |
+
|
| 106 |
+
Diffusion models can learn meaningful visual structure even at extremely small scales.
|
| 107 |
+
|
| 108 |
+
Future work:
|
| 109 |
+
|
| 110 |
+
Conditional generation (class-based)
|
| 111 |
+
Text-to-image (v2.0)
|
| 112 |
+
DDIM sampling
|
| 113 |
+
Larger model variants
|
| 114 |
+
💡 Motivation
|
| 115 |
+
|
| 116 |
+
Most diffusion research focuses on scaling up.
|
| 117 |
+
|
| 118 |
+
This project explores the opposite direction:
|
| 119 |
+
|
| 120 |
+
What is the minimum viable diffusion model?
