-As of the time of writing this you need this preview driver for best results:
-https://www.amd.com/en/resources/support-articles/release-notes/RN-AMDGPU-WINDOWS-PYTORCH-PREVIEW.html
-
-HOW TO RUN:
-
-If you have a AMD gpu:
-
-run_amd_gpu.bat
-
-If you have memory issues you can try disabling the smart memory management by running comfyui with:
-
-run_amd_gpu_disable_smart_memory.bat
-
-IF YOU GET A RED ERROR IN THE UI MAKE SURE YOU HAVE A MODEL/CHECKPOINT IN: ComfyUI\models\checkpoints
-
-You can download the stable diffusion XL one from: https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0_0.9vae.safetensors
-
-
-RECOMMENDED WAY TO UPDATE:
-To update the ComfyUI code: update\update_comfyui.bat
-
-
-TO SHARE MODELS BETWEEN COMFYUI AND ANOTHER UI:
-In the ComfyUI directory you will find a file: extra_model_paths.yaml.example
-Rename this file to: extra_model_paths.yaml and edit it with your favorite text editor.

-# The Comfy guide to Quantization
-
-
-## How does quantization work?
-
-Quantization aims to map a high-precision value x_f to a lower precision format with minimal loss in accuracy. These smaller formats then serve to reduce the models memory footprint and increase throughput by using specialized hardware.
-
-When simply converting a value from FP16 to FP8 using the round-nearest method we might hit two issues:
-- The dynamic range of FP16 (-65,504, 65,504) far exceeds FP8 formats like E4M3 (-448, 448) or E5M2 (-57,344, 57,344), potentially resulting in clipped values
-- The original values are concentrated in a small range (e.g. -1,1) leaving many FP8-bits "unused"
-
-By using a scaling factor, we aim to map these values into the quantized-dtype range, making use of the full spectrum. One of the easiest approaches, and common, is using per-tensor absolute-maximum scaling.
-
-```
-absmax = max(abs(tensor))
-scale = amax / max_dynamic_range_low_precision
-
-# Quantization
-tensor_q = (tensor / scale).to(low_precision_dtype)
-
-# De-Quantization
-tensor_dq = tensor_q.to(fp16) * scale
-
-tensor_dq ~ tensor
-```
-
-Given that additional information (scaling factor) is needed to "interpret" the quantized values, we describe those as derived datatypes.
-
-
-## Quantization in Comfy
-
-```
-QuantizedTensor (torch.Tensor subclass)
-  ↓ __torch_dispatch__
-Two-Level Registry (generic + layout handlers)
-  ↓
-MixedPrecisionOps + Metadata Detection
-```
-
-### Representation
-
-To represent these derived datatypes, ComfyUI uses a subclass of torch.Tensor to implements these using the `QuantizedTensor` class found in `comfy/quant_ops.py`
-
-A `Layout` class defines how a specific quantization format behaves:
-- Required parameters
-- Quantize method
-- De-Quantize method
-
-```python
-from comfy.quant_ops import QuantizedLayout
-
-class MyLayout(QuantizedLayout):
-    @classmethod
-    def quantize(cls, tensor, **kwargs):
-        # Convert to quantized format
-        qdata = ...
-        params = {'scale': ..., 'orig_dtype': tensor.dtype}
-        return qdata, params
-    
-    @staticmethod
-    def dequantize(qdata, scale, orig_dtype, **kwargs):
-        return qdata.to(orig_dtype) * scale
-```
-
-To then run operations using these QuantizedTensors we use two registry systems to define supported operations. 
-The first is a **generic registry** that handles operations common to all quantized formats (e.g., `.to()`, `.clone()`, `.reshape()`).
-
-The second registry is layout-specific and allows to implement fast-paths like nn.Linear.
-```python
-from comfy.quant_ops import register_layout_op
-
-@register_layout_op(torch.ops.aten.linear.default, MyLayout)
-def my_linear(func, args, kwargs):
-    # Extract tensors, call optimized kernel
-    ...
-```
-When `torch.nn.functional.linear()` is called with QuantizedTensor arguments, `__torch_dispatch__` automatically routes to the registered implementation.
-For any unsupported operation, QuantizedTensor will fallback to call `dequantize` and dispatch using the high-precision implementation.
-
-
-### Mixed Precision
-
-The `MixedPrecisionOps` class (lines 542-648 in `comfy/ops.py`) enables per-layer quantization decisions, allowing different layers in a model to use different precisions. This is activated when a model config contains a `layer_quant_config` dictionary that specifies which layers should be quantized and how.
-
-**Architecture:**
-
-```python
-class MixedPrecisionOps(disable_weight_init):
-    _layer_quant_config = {}  # Maps layer names to quantization configs
-    _compute_dtype = torch.bfloat16  # Default compute / dequantize precision
-```
-
-**Key mechanism:**
-
-The custom `Linear._load_from_state_dict()` method inspects each layer during model loading:
-- If the layer name is **not** in `_layer_quant_config`: load weight as regular tensor in `_compute_dtype`
-- If the layer name **is** in `_layer_quant_config`: 
-  - Load weight as `QuantizedTensor` with the specified layout (e.g., `TensorCoreFP8Layout`)
-  - Load associated quantization parameters (scales, block_size, etc.)
-
-**Why it's needed:**
-
-Not all layers tolerate quantization equally. Sensitive operations like final projections can be kept in higher precision, while compute-heavy matmuls are quantized. This provides most of the performance benefits while maintaining quality.
-
-The system is selected in `pick_operations()` when `model_config.layer_quant_config` is present, making it the highest-priority operation mode.
-
-
-## Checkpoint Format
-
-Quantized checkpoints are stored as standard safetensors files with quantized weight tensors and associated scaling parameters, plus a `_quantization_metadata` JSON entry describing the quantization scheme.
-
-The quantized checkpoint will contain the same layers as the original checkpoint but:
-- The weights are stored as quantized values, sometimes using a different storage datatype. E.g. uint8 container for fp8.
-- For each quantized weight a number of additional scaling parameters are stored alongside depending on the recipe.
-- We store a metadata.json in the metadata of the final safetensor containing the `_quantization_metadata` describing which layers are quantized and what layout has been used.
-
-### Scaling Parameters details
-We define 4 possible scaling parameters that should cover most recipes in the near-future:
-- **weight_scale**: quantization scalers for the weights
-- **weight_scale_2**: global scalers in the context of double scaling
-- **pre_quant_scale**: scalers used for smoothing salient weights
-- **input_scale**: quantization scalers for the activations
-
-| Format | Storage dtype | weight_scale | weight_scale_2 | pre_quant_scale | input_scale |
-|--------|---------------|--------------|----------------|-----------------|-------------|
-| float8_e4m3fn | float32 | float32 (scalar) | - | - | float32 (scalar) |
-
-You can find the defined formats in `comfy/quant_ops.py` (QUANT_ALGOS).
-
-### Quantization Metadata
-
-The metadata stored alongside the checkpoint contains:
-- **format_version**: String to define a version of the standard
-- **layers**: A dictionary mapping layer names to their quantization format. The format string maps to the definitions found in `QUANT_ALGOS`. 
-
-Example:
-```json
-{
-  "_quantization_metadata": {
-    "format_version": "1.0",
-    "layers": {
-      "model.layers.0.mlp.up_proj": "float8_e4m3fn",
-      "model.layers.0.mlp.down_proj": "float8_e4m3fn",
-      "model.layers.1.mlp.up_proj": "float8_e4m3fn"
-    }
-  }
-}
-```
-
-
-## Creating Quantized Checkpoints
-
-To create compatible checkpoints, use any quantization tool provided the output follows the checkpoint format described above and uses a layout defined in `QUANT_ALGOS`.
-
-### Weight Quantization
-
-Weight quantization is straightforward - compute the scaling factor directly from the weight tensor using the absolute maximum method described earlier. Each layer's weights are quantized independently and stored with their corresponding `weight_scale` parameter.
-
-### Calibration (for Activation Quantization)
-
-Activation quantization (e.g., for FP8 Tensor Core operations) requires `input_scale` parameters that cannot be determined from static weights alone. Since activation values depend on actual inputs, we use **post-training calibration (PTQ)**:
-
-1. **Collect statistics**: Run inference on N representative samples
-2. **Track activations**: Record the absolute maximum (`amax`) of inputs to each quantized layer
-3. **Compute scales**: Derive `input_scale` from collected statistics
-4. **Store in checkpoint**: Save `input_scale` parameters alongside weights
-
-The calibration dataset should be representative of your target use case. For diffusion models, this typically means a diverse set of prompts and generation parameters.
