# ComfyUI Ultimate Auto Sampler Config Grid Testing Suite




Want to support development of this project? Buy me a coffee on Ko-fi:







  







**A professional-grade benchmarking and "IDE-like" testing suite for ComfyUI.**

Stop guessing which Sampler, Scheduler, Prompt, Denoise, Model, Lora or CFG value works best. This custom node suite allows you to generate massive Cartesian product grids, view them in an interactive infinite-canvas dashboard, and refine your settings with a "Revise & Generate" workflow without ever leaving the interface.



---

## 🌟 Key Features

### 🚀 Powerful Grid Generation

* **Cartesian Product Engine:** Automatically generates every permutation of your input settings. Test unlimited Samplers, Schedulers, CFG scales, Sizes, Prompts, LoRA combinations all in one go.

* **Non-Standard Model Support:** Full support for SD3, Flux, Z-Image, and other non-standard architectures with automatic latent channel detection.

* **Multi-Model Support:** Test multiple checkpoints in a single run by passing an array of model names or folder paths.

* **Multi-LoRA Stacking:** Layer multiple LoRAs with custom strengths using the `+` separator. Supports folder expansion for testing entire LoRA directories.

* **Auto LoRA Trigger Words:** Automatically fetches and appends LoRA trigger words from CivitAI API using SHA256 hash lookup. Results are cached locally for offline use.

* **Multi-Seed Generation:** Add extra random variations per config with the `add_random_seeds_to_gens` parameter - perfect for evaluating consistency.

* **Smart Caching:** Intelligently skips model and LoRA reloading when consecutive runs share the same resources, making generation instant for parameter tweaks.

* **Stop & Resume:** Intelligent skip detection - if you stop a generation mid-run, resuming will skip already-generated images and continue where you left off.

* **Advanced Skip Logic:** Uses conditioning tensor hashing to detect prompt changes even when using pre-encoded conditioning from CLIP nodes.

* **LoRA Compatibility Detection:** Automatically detects and skips incompatible LoRAs with detailed error reporting, preventing log spam.

* **VAE Batching:** Includes a `vae_batch_size` input to batch decode images, significantly speeding up large grid runs.

* **Live Dashboard Updates:** Configure `flush_batch_every` to update the dashboard incrementally (e.g., every 4 images) instead of waiting for the entire batch to complete.

### 🎨 Interactive Dashboard (The "IDE")

* **Infinite Canvas with Pan/Zoom:** Google Maps-style navigation with mouse drag, mousewheel zoom, and keyboard shortcuts.

* **Virtual Scrolling:** Ultra-optimized rendering handles thousands of images smoothly by only loading visible items - scroll through 5000+ images without lag.

* **Mobile Touch Support:** Full pinch-to-zoom and pan gestures on mobile devices with optimized touch controls.

* **Fullscreen Mode:** Click the fullscreen button (⛶) to expand the dashboard to fill your entire screen.

* **Favorites System:** Star your best images with a ⭐ button - favorites are collected in a separate gold JSON bar for easy export.

* **Smart Filtering:** Toggle visibility by Model, Sampler, Scheduler, Denoise, or LoRA type.

  - **Shift+Click:** Isolate a single filter (deselect all others) for quick A/B testing

* **Intelligent Sorting:** Instantly sort your grid by **Oldest**, **Newest**, or **Fastest** (generation time). Your preference is saved to localStorage.

* **Go to Image #:** Jump directly to any image number with the "Go to #" input field in the header.

* **Auto-Load Sessions:** Dashboard automatically loads when generation starts - no manual session name entry needed.

* **Session Management:** Save and Load previous testing sessions directly from the UI.

* **Keyboard Navigation:**

  - `Space` - Pan down one row

  - `Shift+Space` - Pan up one row  

  - `Arrow Keys` - Pan in any direction

  - `+/-` - Zoom in/out

  - `0` - Reset zoom to 1:1

  - `F` - Auto-fit first row to viewport width

### ⚡ The "Revise & Generate" Workflow

* **One-Click Revision:** Click "REVISE" on any image to open a detail view.

* **Complete Metadata View:** Shows model, seed, prompts (with trigger words), and all generation parameters.

* **Instant Tweak:** Adjust CFG, Steps, or Sampler for *just that specific image*.

* **Generate New:** A "GENERATE NEW" button queues the new variation immediately without needing to disconnect wires or change the main batch.

* **Similarity Reel:** The revision modal shows a side-scrolling reel of all other images that share the same seed, allowing for perfect A/B comparison.

* **Multiple Prompts:** Use an array to run multiple prompts in one run without re-running your entire workflow: `["picture of a forest", "mountains at night", "masterpiece, painting of dog"]`

### 🧹 Curation & JSON Export

* **Rejection System:** Click the red **"✕"** on bad generations to hide them.

* **Triple JSON Bars (Horizontal Layout):**

    * **Green Bar (Left):** Automatically groups all *accepted* configs into a clean, optimized JSON array ready for copy-pasting.

    * **Gold Bar (Center):** Contains all *favorited* configs - your best-performing settings.

    * **Red Bar (Right):** Collects all *rejected* configs so you know exactly what settings to avoid.

## 🛠️ Usage Guide

### 1. The Nodes

This suite consists of two main nodes found under the `sampling/testing` category:

1. **Ultimate Sampler Grid (Generator):** The engine. It handles model loading, grid generation, and saving.

2. **Ultimate Grid Dashboard (Viewer):** The display. It renders the HTML output.

**Basic Setup:**

* Add the **Generator** node.

* Connect your Checkpoint, CLIP, and VAE (optional, see "Hybrid Inputs" below).

* Add the **Viewer** node.

* Connect the `dashboard_html` output from the Generator to the input of the Viewer.

### 2. Generator Node Parameters

#### Core Settings

* **`ckpt_name`**: Default checkpoint to use (can be overridden by `model` in JSON or optional input).

* **`positive_text`** / **`negative_text`**: Prompts. Supports arrays: `["prompt 1", "prompt 2"]` or JSON arrays.

* **`seed`**: Base seed. Each config uses this seed unless overridden.

* **`denoise`**: Denoise strength(s). Supports single value, array, or comma-separated: `"1.0"` or `"0.8, 0.9, 1.0"`.

#### Performance Settings

* **`vae_batch_size`**: How many images to decode at once.

  - `4` (default): Good for 8-12GB VRAM

  - `12-24`: For 24GB+ VRAM  

  - `-1`: Decode all images at once (fastest, but risky)

  

* **`flush_batch_every`**: Update dashboard every X images (0 = use VAE batch size).

  - `0`: Wait until VAE batch is full

  - `4`: Update dashboard every 4 images (recommended for live monitoring)

#### Advanced Settings

* **`overwrite_existing`**: 

  - `False` (default): Skip already-generated images (resume mode)

  - `True`: Re-generate everything

  

* **`add_random_seeds_to_gens`**: Generate X extra random variations per config.

  - `0` (default): Only use base seed

  - `3`: Generate 3 additional random seed variations per config

  - Random seeds are deterministic per base seed - changing base seed generates new random variations

* **`lookup_and_append_lora_triggerwords`**: Automatically fetch and append LoRA trigger words.

  - `False` (default): Use prompts as-is

  - `True`: Calculate SHA256 hash of each LoRA, query CivitAI API for trigger words, cache results locally, and prepend to prompts

  - Example: LoRA has trigger word "character_name" → Prompt becomes "character_name, your original prompt"

  - Cache stored in `loras_tags.json` for offline use

* **`session_name`**: Folder name where results are saved (`ComfyUI/output/benchmarks/{session_name}/`).

### 3. The JSON Configuration

The `configs_json` widget determines your grid. It accepts an array of objects. All fields support single values or arrays.

**Basic Example:**

```json

[

  {

    "sampler": ["euler", "dpmpp_2m"],

    "scheduler": ["normal", "karras"],

    "steps": [20, 30],

    "cfg": [7.0, 8.0]

  }

]

```

*Generates 16 images (2 samplers × 2 schedulers × 2 steps × 2 cfg)*

**Advanced Features:**

#### Multi-Model Testing

```json

[

  {

    "sampler": "euler",

    "scheduler": "normal", 

    "steps": 20,

    "cfg": 7.0,

    "model": [

      "sd_xl_base_1.0.safetensors",

      "juggernautXL_v9.safetensors",

      "ponyDiffusionV6XL_v6.safetensors"

    ]

  }

]

```

*Tests 3 different models with the same settings*

#### Folder Expansion

```json

[

  {

    "sampler": "euler",

    "scheduler": "normal",

    "steps": 20, 

    "cfg": 7.0,

    "model": "sdxl_models/"  // Tests ALL models in this folder

  }

]

```

#### Multi-LoRA with Stacking

```json

[

  {

    "sampler": "euler",

    "scheduler": "normal",

    "steps": 20,

    "cfg": 7.0,

    "lora": [

      "None",

      "style_lora.safetensors:0.8:1.0",

      "style_lora.safetensors:0.5:1.0 + detail_lora.safetensors:1.0:1.0",

      "loras_folder/"  // Tests ALL loras in folder

    ]

  }

]

```

*LoRA format: `filename:strength_model:strength_clip`*  

*Stack with `+` separator: `lora1:0.8:1.0 + lora2:1.0:1.0`*

#### Resolution Grid

```json

// In resolutions_json input:

[

  [1024, 1024],

  [1024, 1536], 

  [1536, 1024]

]

```

#### Multiple Prompts

```json

// In positive_text input (as JSON array):

[

  "a beautiful landscape, mountains, sunset",

  "cyberpunk city at night, neon lights",

  "portrait of a warrior, detailed armor"

]

```

### 4. Hybrid Inputs (Optional)

The Generator node features built-in widgets for Model Selection and Prompts, but also has **Optional Inputs** for flexibility:

* **Standalone Mode:** Use the dropdown menu to select a checkpoint and type prompts into the text boxes.

* **Hybrid Mode:** Connect a `MODEL`, `CLIP`, `VAE`, or `CONDITIONING` wire. The node will automatically ignore the internal widget and use the connected input instead.

* **Non-Standard Models:** For SD3, Flux, Z-Image, and other architectures:

  - Connect `optional_model`, `optional_clip`, and `optional_vae` from your model loader

  - Connect `optional_positive` and `optional_negative` for pre-encoded conditioning

  - The node automatically detects latent channel count (4 for SD1.5/SDXL, 16 for SD3/Flux/Z-Image)

  - Skip detection uses conditioning tensor hashing to properly detect prompt changes

* **Latent Input:** Connect a `LATENT` to use img2img or upscaling workflows.

  - For SD3/Flux: Use `EmptySD3LatentImage` instead of `EmptyLatentImage`

  - Latent dimensions are automatically preserved

## 🔧 Performance Tips

### For Large Batches (1000+ images)

1. Set `flush_batch_every: 10-20` to see progress updates without overwhelming the browser

2. Use `vae_batch_size: 8-12` (balance between speed and VRAM)

3. Enable `overwrite_existing: False` so you can stop/resume safely

4. Close other browser tabs to free up memory for virtual scrolling

### For Multi-Model Testing

1. Sort models by similarity in the JSON (reduces cache invalidation)

2. Use identical LoRA/prompt settings across models for fair comparison

3. Use `add_random_seeds_to_gens: 2-3` to evaluate model consistency

### For Memory-Constrained Systems

1. Lower `vae_batch_size` to 1-2

2. Test one model at a time instead of multi-model arrays

3. Use smaller resolution grids

4. Filter the dashboard to reduce visible cards

---

## ⚠️ Troubleshooting

### Generation Issues

* **"Session not found":** Ensure the `session_name` matches a folder inside `ComfyUI/output/benchmarks/`.

* **OOM Errors:** If you crash during decoding, lower the `vae_batch_size` to 1 or 2.

* **Images not resuming:** Make sure `overwrite_existing: False`. Check console for skip messages.

* **Random seeds different each run:** This is intentional - random seeds are tied to the base seed. Change the base `seed` parameter to generate new random variations.

* **"mat1 and mat2 shapes cannot be multiplied" error:**

  - This indicates a model architecture mismatch

  - For SD3/Flux/Z-Image models, ensure you connect ALL optional inputs (model, clip, vae, positive, negative)

  - Check that your LoRAs are compatible with your model architecture

  - Incompatible LoRAs are automatically detected and skipped with detailed error messages

* **Dashboard not auto-loading:**

  - Ensure the dashboard node is connected to the sampler's `dashboard_html` output

  - Check browser console for connection errors

  - Try manually clicking "RELOAD / SHOW SESSION" button

### Dashboard Issues

* **Cards not appearing:** Click inside the viewport area first to give it focus, then use keyboard navigation.

* **Can't scroll/pan:** Right-click on the canvas area to focus it, or click and drag with left mouse button.

* **Slow performance with many images:** The virtual scrolling should handle 5000+ images smoothly. If it's slow, try:

  - Closing other browser tabs

  - Reducing browser zoom to 100%

  - Clearing localStorage (`F12` → Console → `localStorage.clear()`)

* **Images not loading:** Scroll slower to give the lazy loader time to fetch images.

* **Hover z-index issues:** Ensure you're using the latest CSS file with `z-index: 999999 !important` on card hover.

* **Mobile touch not working:** 

  - Ensure you're using the latest version with touch support

  - Try tapping and holding to reveal card buttons

  - Use two fingers for pinch-to-zoom

### LoRA & Trigger Word Issues

* **Trigger words not appearing:** 

  - Enable `lookup_and_append_lora_triggerwords` in the sampler node

  - Ensure internet connection for first-time LoRA lookup

  - Check `loras_tags.json` in ComfyUI root for cached results

* **"INCOMPATIBLE LORA DETECTED" messages:**

  - This is normal - the node automatically skips incompatible LoRAs

  - Check the summary at the end of generation for list of incompatible LoRAs

  - Ensure your LoRAs match your model architecture (SD1.5 LoRAs won't work on SDXL, etc.)

### Browser Compatibility

* **Chrome/Edge:** Full support ✅

* **Firefox:** Full support ✅  

* **Safari:** Mostly works, some keyboard shortcuts may conflict

* **Mobile:** Full touch support ✅ (iOS Safari, Android Chrome tested)
