+|------------|---------------------|
+| 40GB+ VRAM | Standard settings (no special optimization needed) |

-- **`--fp8_scaled`**: Enables training the DiT in scaled FP8 format.
-- **`--fp8_vl`**: Use FP8 for the VLM text encoder.
-- **`--blocks_to_swap <number>`**: Swaps blocks between CPU and GPU to reduce VRAM usage. Higher numbers save more VRAM but reduce training speed.

+The `hunyuan_image_minimal_inference.py` script allows you to generate images using trained LoRA models. Here's a basic usage example:
+
+```bash
+python hunyuan_image_minimal_inference.py \
+  --dit "<path to hunyuanimage2.1.safetensors>" \
+  --text_encoder "<path to qwen_2.5_vl_7b.safetensors>" \

+  --vae "<path to hunyuan_image_2.1_vae_fp16.safetensors>" \
+  --lora_weight "<path to your trained LoRA>" \
+  --lora_multiplier 1.0 \
+  --prompt "A cute cartoon penguin in a snowy landscape" \
+  --image_size 2048 2048 \
+  --infer_steps 50 \
+  --guidance_scale 3.5 \
+  --flow_shift 5.0 \
+  --seed 542017 \
+  --save_path "output_image.png"
+```
+
+**Key Options:**
+- `--fp8_scaled`: Use scaled FP8 format for reduced VRAM usage during inference
+- `--blocks_to_swap`: Swap blocks to CPU to reduce VRAM usage
+- `--image_size`: Resolution (inference is most stable at 2048x2048)
+- `--guidance_scale`: CFG scale (default: 3.5)
