 # Zen3 Image Fast
 
-**Zen3 Image Fast** is a high-speed text-to-image generation model developed by [Hanzo AI](https://hanzo.ai) as part of the Zen model family. It generates high-quality images from text prompts in just 1-4 inference steps.
+Fast inference variant of Zen3 Image for low-latency image generation.
 
 ## Overview
 
-Zen3 Image Fast is optimized for rapid image generation without sacrificing quality. Using a rectified flow transformer architecture, it produces 1024x1024 images in minimal inference steps, making it ideal for real-time applications and interactive workflows.
-
-### Key Features
+Built on **Zen MoDE (Mixture of Distilled Experts)** architecture with 12B parameters.
 
-- **Ultra-fast generation**: 1-4 step inference for near-instant image creation
-- **High resolution**: Native 1024x1024 output
-- **Rectified flow**: Advanced flow matching for efficient sampling
-- **Production ready**: Optimized for low-latency deployment
+Developed by [Hanzo AI](https://hanzo.ai) and the [Zoo Labs Foundation](https://zoo.ngo).
 
-## Usage
+## Quick Start
 
 ```python
 from diffusers import AutoPipelineForText2Image
 import torch
 
-pipe = AutoPipelineForText2Image.from_pretrained(
-    "zenlm/zen3-image-fast",
-    torch_dtype=torch.bfloat16
-)
-pipe.to("cuda")
-
-image = pipe(
-    "A futuristic cityscape at sunset with neon lights",
-    num_inference_steps=4,
-    guidance_scale=0.0,
-    height=1024,
-    width=1024,
-).images[0]
+model_id = "zenlm/zen3-image-fast"
+pipe = AutoPipelineForText2Image.from_pretrained(model_id, torch_dtype=torch.bfloat16)
+pipe = pipe.to("cuda")
 
+image = pipe("A serene mountain landscape at sunset, photorealistic").images[0]
 image.save("output.png")
 ```
