-# Diffusion
-
-SGLang supports two categories of diffusion models for different use cases. This page covers image and video generation; for diffusion LLMs, see [Diffusion LLMs](diffusion_llms.md).
-
-## Image & Video Generation Models
-
-For generating images and videos from text prompts, SGLang supports [many](../diffusion/compatibility_matrix.md) models like:
-
-- **FLUX, Qwen-Image** - High-quality image generation
-- **Wan 2.2, HunyuanVideo** - Video generation
-
-```bash
-# Example: Launch FLUX for image generation
-python3 -m sglang.launch_server \
-  --model-path black-forest-labs/FLUX.2-klein-4B \
-  --host 0.0.0.0 --port 30000
-```

-# Diffusion Language Models (dLLMs)
-
-These are text-generation models that use diffusion (denoising) instead of autoregressive decoding:
-
-- **LLaDA** - Large Language Diffusion with mAsking
-
-```bash
-# Example: Launch LLaDA for text generation
-python3 -m sglang.launch_server \
-  --model-path GSAI-ML/LLaDA-8B-Instruct \
-  --host 0.0.0.0 --port 30000
