 The CLIP model will be deleted from memory after use, while your encoded text (data) continues downstream into the workflow.
 
+
+## 🔍 How This Node Differs from Normal ComfyUI Memory Management
+
+By default, ComfyUI has its own memory manager that tries to balance VRAM and system RAM usage:
+
+When a model is not needed in VRAM, ComfyUI may move it from VRAM to system RAM (“unloading” it) so it can be reloaded faster later.
+
+This is efficient if you have enough RAM, because models don’t need to be reloaded from disk each time.
+
+However, in low RAM environments, this behavior can cause your system RAM to fill up, leading to slowdowns or even OOM crashes.
+
+
+## ⚖️ Downsides of Using This Node
+
+While this node is powerful for low-memory setups, there are trade-offs:
+
+**Slower reloads**
+
+Since the model is completely deleted, if you need it again later in the workflow, ComfyUI must reload it from disk.
+
+Disk loads are much slower than reloading from RAM.
+
+**No caching benefit**
+
+ComfyUI’s memory manager caches models to speed up reuse.
+
+This node removes that cache advantage; models won’t be instantly available later.
+
+**Workflow fragility**
+
+If another node down the line expects the model still to exist, your workflow may break.
+
+This node is best used only when you’re sure the model will not be needed again.
+
+**One-way action**
+
+Once deleted, the model is gone. There’s no “undo” unless it is explicitly reloaded by another loader node.
+
+
+## 📝 When to Use This Node
+
+You have low VRAM and low system RAM.
+
+You want to run multiple heavy models in a single workflow without hitting OOM errors.
+
+You are done using a model (e.g., CLIP for text encoding, or a helper model), and it won’t be needed again later.
+
+
+## 🚫 When Not to Use This Node
+
+If you have enough RAM and want to benefit from ComfyUI’s smart caching.
+
+If you plan to use the same model multiple times in the workflow.
