--- name: comfyui-flux description: "Generate images locally using ComfyUI + Flux.1 Dev model. Zero API cost, strong text rendering. Use when: generating images locally, creating slides/PPT graphics, or when user says 'local image', '本地生图', 'flux', 'comfyui'. Requires ComfyUI running at localhost:8188. For face-consistent selfies, prefer wanx-image-generation skill instead." --- # ComfyUI Flux.1 Dev — Local Image Generation Generate images locally via ComfyUI API + Flux.1 Dev. No API cost, excellent text rendering. ## Prerequisites ComfyUI must be running (default port 8200): ```bash # 启动 bash /Users/chrisliu/ComfyUI/start.sh # 关闭 bash /Users/chrisliu/ComfyUI/stop.sh ``` Override URL via env: `COMFYUI_URL=http://127.0.0.1:8200` Models (already installed): - `flux1-dev.safetensors` (diffusion model) - `t5xxl_fp8_e4m3fn.safetensors` + `clip_l.safetensors` (text encoders) - `ae.safetensors` (VAE) ## Usage ```bash python3 {baseDir}/scripts/flux_generate.py --prompt "PROMPT" [OPTIONS] ``` ### Basic ```bash python3 {baseDir}/scripts/flux_generate.py \ --prompt "A professional presentation slide with title 'AI Revolution' in bold white text on dark gradient background" ``` ### Custom Size (e.g. 16:9 for PPT slides) ```bash python3 {baseDir}/scripts/flux_generate.py \ --prompt "..." \ --width 1344 --height 768 ``` ## Parameters | Parameter | Default | Description | |---|---|---| | `--prompt` | (required) | Image description | | `--negative` | "" | Negative prompt | | `--width` | 1024 | Image width | | `--height` | 1024 | Image height | | `--steps` | 20 | Sampling steps (more = better but slower) | | `--cfg` | 1.0 | CFG scale (Flux works best at 1.0) | | `--seed` | random | Reproducibility seed | | `--output` | auto | Output path (default: generated-images/flux-{ts}.png) | | `--timeout` | 600 | Max wait seconds | ## Common Sizes | Use Case | Size | Flag | |---|---|---| | Square | 1024×1024 | (default) | | PPT 16:9 | 1344×768 | `--width 1344 --height 768` | | Portrait | 768×1344 | `--width 768 --height 1344` | | Landscape | 1344×768 | `--width 1344 --height 768` | ## PuLID Face-Consistent Generation Generate images with a reference face using PuLID-Flux (zero API cost, zero censorship): ```bash python3 {baseDir}/scripts/pulid_generate.py \ --prompt "PROMPT" \ --ref-image path/to/face.jpg [OPTIONS] ``` ### Basic (face-consistent portrait) ```bash python3 {baseDir}/scripts/pulid_generate.py \ --prompt "a girl sitting in a cafe, warm afternoon light, casual outfit" \ --ref-image avatars/kimi.jpg ``` ### Custom size + weight ```bash python3 {baseDir}/scripts/pulid_generate.py \ --prompt "a girl on the beach at sunset, wearing a sundress" \ --ref-image avatars/kimi.jpg \ --width 1024 --height 1024 \ --weight 1.2 ``` ### PuLID Parameters | Parameter | Default | Description | |---|---|---| | `--prompt` | (required) | Image description | | `--ref-image` | (required) | Reference face image path | | `--negative` | "" | Negative prompt | | `--width` | 768 | Image width | | `--height` | 1024 | Image height (portrait default) | | `--steps` | 10 | Sampling steps (PuLID works well with fewer) | | `--cfg` | 3.5 | Guidance scale | | `--seed` | random | Reproducibility seed | | `--weight` | 1.0 | Face similarity weight (0.0-5.0, higher = more similar) | | `--start-at` | 0.0 | PuLID start timestep | | `--end-at` | 1.0 | PuLID end timestep | | `--output` | auto | Output path (default: generated-images/pulid-{ts}.png) | | `--timeout` | 600 | Max wait seconds | ### PuLID Notes - Default portrait orientation (768×1024) — good for face shots - `--weight 1.0` is balanced; increase to 1.2-1.5 for stronger likeness - `--steps 10` is enough for PuLID; increase to 20 for more detail - First run is slower (loads PuLID + InsightFace + EVA-CLIP models) - No content censorship — can generate anything locally ## Strengths vs API (qwen-image) - ✅ Free — no API cost - ✅ Excellent text/typography rendering (great for slides!) - ✅ High detail and consistency - ⚠️ Slower on Mac (~1-3 min per image) - ❌ No native face-consistency (use PuLID/IPAdapter for that) ## Output Prints `MEDIA:<path>` — auto-attached to chat reply. Default saves to `generated-images/`. ## Troubleshooting If ComfyUI is not running, the script exits with an error and prints startup instructions.
