-# ComfyUI PyWorker
-
-This is the base PyWorker for ComfyUI. It provides a unified interface for running any ComfyUI workflow through a proxy-based architecture.
-
-The cost for each request has a static value of `1`.  ComfyUI does not handle concurrent workloads and there is no current provision to load multiple instances of ComfyUI per worker node.
-
-## Requirements
-
-This worker requires both [ComfyUI](https://github.com/comfyanonymous/ComfyUI) and [ComfyUI API Wrapper](https://github.com/ai-dock/comfyui-api-wrapper).
-
-A docker image is provided but you may use any if the above requirements are met.
-
-## Benchmarking
-
-A simple image generation benchmark runs when each worker initializes to validate GPU performance and identify underperforming machines.
-
-The benchmark uses Stable Diffusion v1.5 with ComfyUI's default text-to-image workflow. Configure the benchmark complexity and duration using these variables:
-
-| Environment Variable | Default Value | Description |
-| -------------------- | ------------- | ----------- |
-| BENCHMARK_TEST_WIDTH | 512 | Image width (pixels) |
-| BENCHMARK_TEST_HEIGHT | 512 | Image height (pixels) |
-| BENCHMARK_TEST_STEPS | 20 | Number of denoising steps |
-
-Each benchmark run uses a random prompt from `misc/test_prompts.txt` and a random seed to ensure consistent GPU load patterns.
-
-### Calibrating Benchmark Duration
-
-To screen for underperforming hardware, set `BENCHMARK_TEST_STEPS` to match your expected production workflow duration. This allows you to identify machines that won't meet performance requirements.
-
-**Example:** If your typical workflow should complete in 90 seconds on acceptable hardware:
-
-```bash
-# 1. Measure it/sec on your reference machine
-# RTX 4090 typically achieves ~43 it/sec with SD1.5
-
-# 2. Calculate required steps
-# 90 seconds × 43 it/sec = 3870 steps
-
-# 3. Configure benchmark
-export BENCHMARK_TEST_STEPS=3870
-
-# 4. Machines completing significantly slower than 90s indicate hardware issues
-```
-
-**Performance expectations:**
-- Benchmark duration should remain consistent across identical GPU models
-- Significant variation (>20%) may indicate thermal, power, or configuration issues
-
-## Endpoint
-
-The worker provides a single endpoint:
-
-- `/generate/sync`: Processes ComfyUI workflows using either predefined modifiers or custom workflow JSON
-
-## Request Format
-
-The worker accepts requests in the following format. Choose either modifier mode OR custom workflow mode:
-
-**Modifier Mode:**
-```json
-{
-  "input": {
-    "request_id": "uuid-string",    // optional - UUID generated if not provided
-    "modifier": "RawWorkflow",
-    "modifications": {
-      "prompt": "a beautiful landscape",
-      "width": 1024,
-      "height": 1024,
-      "steps": 20,
-      "seed": 123456789
-    },
-    "s3": { ... },       // optional
-    "webhook": { ... }   // optional
-  }
-}
-```
-
-**Custom Workflow Mode:**
-```json
-{
-  "input": {
-    "request_id": "uuid-string",    // optional - UUID generated if not provided
-    "workflow_json": {
-      // Complete ComfyUI workflow JSON
-    },
-    "s3": { ... },       // optional
-    "webhook": { ... }   // optional
-  }
-}
-```
-
-## Request Fields
-
-### Required Fields
-
-- **`input`**: Contains the main workflow data
-- **`input.request_id`**: Unique identifier for the request
-
-### Workflow Mode (Choose One)
-
-You must provide either `modifier` OR `workflow_json`, but not both:
-
-#### Option 1: Modifier Mode
-- **`input.modifier`**: Name of the predefined workflow modifier (e.g., "Text2Image")
-- **`input.modifications`**: Parameters to pass to the modifier
-
-#### Option 2: Custom Workflow Mode  
-- **`input.workflow_json`**: Complete ComfyUI workflow JSON
-
-### Optional Fields
-
-- **`input.s3`**: S3 configuration for file storage
-- **`input.webhook`**: Webhook configuration for notifications
-
-These configurations can be provided in the request JSON or via environment variables. Request-level configuration takes precedence over environment variables.
-
-#### S3 Configuration
-
-**Via Request JSON:**
-```json
-"s3": {
-  "access_key_id": "your-s3-access-key",
-  "secret_access_key": "your-s3-secret-access-key", 
-  "endpoint_url": "https://my-endpoint.backblaze.com",
-  "bucket_name": "your-bucket",
-  "region": "us-east-1"
-}
-```
-
-**Via Environment Variables:**
-```bash
-S3_ACCESS_KEY_ID=your-key
-S3_SECRET_ACCESS_KEY=your-secret
-S3_BUCKET_NAME=your-bucket
-S3_ENDPOINT_URL=https://s3.amazonaws.com
-S3_REGION=us-east-1
-```
-
-#### Webhook Configuration
-
-**Via Request JSON:**
-```json
-"webhook": {
-  "url": "your-webhook-url",
-  "extra_params": {
-    "custom_field": "value"
-  }
-}
-```
-
-**Via Environment Variables:**
-```bash
-WEBHOOK_URL=https://your-webhook.com  # Default webhook URL
-WEBHOOK_TIMEOUT=30                   # Webhook timeout in seconds
-```
-
-## Examples
-
-### Basic Text-to-Image (Modifier Mode)
-
-```json
-{
-  "input": {
-    "modifier": "Text2Image",
-    "modifications": {
-      "prompt": "a cat sitting on a windowsill",
-      "width": 512,
-      "height": 512,
-      "steps": 20,
-      "seed": 42
-    }
-  }
-}
-```
-
-### Custom Workflow Mode
-
-```json
-{
-  "input": {
-    "request_id": "67890",    // optional - using custom ID for tracking
-    "workflow_json": {
-      "3": {
