+# 🚀 ComfyUI Any-Device Offload
+
+**Force any Model, VAE, or CLIP to any GPU or CPU—and keep it there (or don't).**
+
+This custom node gives you total control over where your models run and where they live in memory. It solves common "Out of Memory" (OOM) errors, enables multi-GPU workflows, and fixes persistent crashes when trying to run modern workflows (like Flux/SD3) on CPUs or secondary GPUs.

+
+
+### ✨ Key Features
+
+* **👇 Manual Device Selection:** Force specific models to run on `cuda:0`, `cuda:1`, `cpu`, or Mac `mps`.
+* **🧠 Intelligent VRAM Management:**
+    * **Keep in Memory (True):** Pin models to VRAM for instant switching.
+    * **Keep in Memory (False):** The "Kill Switch." Automatically unloads the Model, CLIP, and VAE from VRAM immediately after generation finishes. It aggressively triggers garbage collection (`gc.collect`) and clears the CUDA cache (`empty_cache`) to free up space for other apps or workflows.
+* **🛠️ VAE Patcher (The Crash Fixer):**
+    * Fixes `RuntimeError: Input type (c10::BFloat16) and bias type (float) should be the same`.
+    * Fixes `CuDNN error: GET was unable to find an engine to execute this computation`.
+    * Automatically converts inputs and weights to matching types (Float32/BFloat16) on the fly without breaking the workflow.
+* **🛡️ CPU "Safe Mode":**
+    * Automatically intercepts **xFormers** calls on CPU (which usually crash with "No operator found") and redirects them to standard PyTorch attention.
+    * Auto-casts Float16 inputs to Float32 when running on CPU to prevent "mat1 and mat2" dtype errors.

+
+### 📦 Installation
+
+1.  Navigate to your ComfyUI custom nodes directory:
+    ```bash
+    cd ComfyUI/custom_nodes/
+    ```
+2.  Clone this repository:
+    ```bash
+    git clone [https://github.com/YOUR_USERNAME/ComfyUI-AnyDeviceOffload](https://github.com/YOUR_USERNAME/ComfyUI-AnyDeviceOffload)
+    ```
+3.  **Restart ComfyUI.**
+
+---
+
+### 📖 Usage
+
+Add the node **"Offload Anything (GPU/CPU)"** to your workflow (found under `utils/hardware`).
+
+#### **Inputs**
+1.  **target_device:**
+    * Select the hardware you want to use (e.g., `cuda:0`, `cuda:1`, `cpu`).
+    * *Note: If you select CPU, the node automatically enables "Safe Mode" to prevent xFormers crashes.*
+2.  **vae_mode:**
+    * **`Original` (Default):** Uses the standard VAE behavior.
+    * **`Vae Patched`:** **⚠️ IMPORTANT:** Select this if you get **black images**, **NaN errors**, or **PyTorch crashes** (especially with Flux, SD3, or secondary GPUs). It forces Float32 precision and auto-casts incoming tensors to ensure compatibility.
+3.  **keep_in_memory:**
+    * **`True`:** Models stay loaded on the device (faster for repeated runs).
+    * **`False`:** Models are aggressively purged from VRAM immediately after the image is saved. Great for low-VRAM cards.
+
+#### **Connections**
+* Connect your **MODEL**, **CLIP**, and/or **VAE** into the inputs.
+* Connect the outputs to your KSampler or VAE Decode.

+
+### 💡 Troubleshooting / FAQ
+
+**Q: My generation crashes with "Input type and bias type should be the same".**
+> **A:** Switch **`vae_mode`** to **`Vae Patched`**. This forces the VAE to handle the data type mismatch (usually caused by Flux/SD3 generating BFloat16 latents while the VAE expects Float32).
+
+**Q: I get an xFormers error when using CPU.**
+> **A:** This node automatically patches xFormers to work on CPU. If you still see it, ensure you are running the latest version of this node and have restarted ComfyUI.
+
+**Q: Why is my GPU memory not clearing?**
+> **A:** Uncheck **`keep_in_memory`**. This activates the "Kill Switch" which forces a `torch.cuda.empty_cache()` immediately after the VAE finishes decoding.
