The `project` field is stored for your reference but not used for filtering. ### 🔗 Common Workflow Patterns ### AI-Assisted with History Backup with the "AF - Save Prompt History" Node ``` [LLM] → [Edit Prompt] ┬ → [CLIP Encode] → [KSampler] └ → [Save History] ``` --- ## AF - Load Prompt History **Purpose:** Load saved prompts using index-based time-travel through your history.

### Quick Reference ``` ┌─────────────────────────────────┐ │ AF - Load Prompt History │ ├─────────────────────────────────┤ │ directory: [AF-PromptHistory ] │ │ filename: [MyProject ▼] │ │ timestamp_index: [0 ] │ ├─────────────────────────────────┤ │ Outputs: │ │ • global_positive │ │ • global_negative │ │ • local_positive │ │ • local_negative │ │ • info (connect to Show Text!) │ └─────────────────────────────────┘ ``` ### How It Works - **Filename dropdown** - Lists all `.json` files in the directory (without .json extension) - **Index selection** - Choose which timestamp to load (0 = newest) - **Info output** - Shows selected prompt content and metadata AF - Load Prompt History - Workflow Download

Always connect `info` → `Show Text` node to see: - Currently selected filename and timestamp - Full content of all 4 prompts being loaded - Total available timestamps count - Error messages if index is out of range ### Example Info Display ``` ══════════════════════════════════════════════════ AF - LOAD PROMPT HISTORY ══════════════════════════════════════════════════ 📄 Filename: MyProject 📊 Available Timestamps: 205 🔢 SELECTED: [126] | 2025-10-29 | 14:32:15 Global Positive: A serene mountain landscape at sunset, golden hour lighting... Global Negative: ugly, deformed, low quality, blurry Local Positive: detailed foreground rocks, wildflowers Local Negative: (empty) ``` **Console Output:** ``` AF Load - ✓ Successfully loaded: ID: 126 | 2025-10-29 14:32:15 ``` ### 🔗 Common Workflow Patterns (suggestions) ### "AF - Load Prompt History" Node, Compare Previous Prompts ``` [Load History: index=0] → [Edit] → [CLIP] ┐ [Load History: index=5] → [Edit] → [CLIP] ├→ [KSampler] [Load History: index=10]→ [Edit] → [CLIP] ┘ ``` ### Pattern 3: Multi-File Workflow ``` [Load: FileA.json] → [Edit Global+] → ┐ [Load: FileB.json] → [Edit Local+] → ├→ [CLIP Encode] [Load: FileC.json] → [Edit Global-] → ┘ ``` --- ## 💡 Pro Tips - **Index 0 is your friend** - Always points to newest prompt - **Info output shows everything** - See exactly what you loaded - **Console logging** - Check ID and timestamp confirmation - **Multiple load nodes** - Each can access different files/indices - **Workflows persist** - Your selections save with the workflow - **Project field** - Use it as a mental note when saving, great for manual inspection --- ### AF - Show Text A very simple node that shows the text connected to the input of the Node

--- ## 🔧 Troubleshooting ### Files not appearing in dropdown - Check ComfyUI console for cache messages - Verify `.json` files exist in `output/{directory}/` - Restart ComfyUI to rebuild cache - Ensure files end with `.json` extension ### Index out of range - Connect `info` output to Show Text to see available count - Example: 205 timestamps = valid indices are 0-204 - The info display shows total count at the top ### Prompts not loading - Ensure filename is selected (not "none") - Check timestamp_index is within range (see info output) - Verify JSON file format matches example above - Look for error messages in console ### Directory not found - Use relative path from ComfyUI root e.g.: `AF-PromptHistory` - Or absolute path: `/full/path/to/directory` - Check folder exists and has read/write permissions --- ## AF - Model Switch A dynamic model switching node that allows you to toggle between multiple model/CLIP/VAE combinations without rewiring your workflow.

On the left the model switch node with it's 2 default inputs and set to auto (Any Switch node style). On the right with all 10 inputs enabled and rail selection set to use rail 3. ### Features - **Dynamic Rails**: Add 2-10 model rails on demand - **Smart AUTO Mode**: Automatically selects the first connected rail - **1-Based Indexing**: Intuitive numbering (Rail 1, Rail 2, Rail 3...) - **Permanent Base Rails**: Rails 1-2 never lose connections when adjusting rail count - **Real-Time Status**: Color-coded display shows active rail instantly - **Flexible Sizing**: Resizable node that preserves your layout preferences ### How It Works The Model Switch acts as a gateway for your model pipeline. Instead of maintaining multiple workflow branches or manually reconnecting loaders, you can: 1. Connect multiple checkpoint loaders (or AIO loaders) to different rails 2. Choose which rail to use via the `selected_rail` parameter 3. The node outputs the MODEL, CLIP, and VAE from your selected rail ### Parameters | Parameter | Type | Range | Description | |-----------|------|-------|-------------| | `number_of_rails` | INT | 2-10 | Number of visible model rails | | `selected_rail` | INT | 0-10 | Active rail: `0` = AUTO (first connected), `1-10` = manual selection | | `status` | STRING | - | Read-only display showing current active rail | ### Status Display Colors - 🟠 **Orange**: AUTO mode - automatically using first connected rail - 🔵 **Blue**: Manual mode - specific rail selected - 🔴 **Red**: Error - no models connected ### Usage Example **Basic Setup:** ``` Checkpoint Loader A → model_1, clip_1, vae_1 Checkpoint Loader B → model_2, clip_2, vae_2 ↓ AF Model Switch (selected_rail: 0) ↓ → model, clip, vae ``` **A/B Testing Workflow:** 1. Set `number_of_rails: 2` 2. Connect two different models to Rails 1 and 2 3. Set `selected_rail: 1` to use first model, `2` for second model 4. Set `selected_rail: 0` for AUTO mode (uses first connected) **Advanced: Quality vs Speed:** 1. Set `number_of_rails: 3` 2. Rail 1: High-quality slow model 3. Rail 2: Balanced model 4. Rail 3: Fast draft model 5. Switch between them by changing `selected_rail` ### Tips - **Rails 1-2 are permanent**: These connections are never lost when you adjust `number_of_rails` - **Rails 3-10 are dynamic**: These are added/removed as needed - **Use with rgthree Group Bypasser**: Bypass entire model loading groups to save memory - only the selected rail's loaders will execute - **AUTO mode is smart**: It will find the first rail with actual data, skipping any bypassed/muted nodes - **Status updates instantly**: No need to run the workflow to see which rail is selected ### Integration with Other Nodes **Works great with:** - `rgthree Context Switch` - for full pipeline switching - `rgthree Group Bypasser` - to disable unused model loaders - `AF - Save Prompt History` - save which model was used with each prompt - Any checkpoint loader or AIO loader node ### Technical Notes - Input names are 1-based: `model_1`, `clip_1`, `vae_1`, etc. - Internally consistent: no confusing 0-based conversions - Minimum node width: 160px - Height auto-adjusts based on number of rails --- ## 📋 Requirements - ComfyUI (recent version recommended) - No external dependencies required - Works with any LLM/text generation nodes, or your manual prompting text nodes --- ## 📄 License MIT License - See LICENSE file for details --- ## 🐛 Issues & Contributions Found a bug?
