本地 SDXL 生图 (axelhu-local-sdxl)

基于 ComfyUI + SDXL 的本地图片生成技能。适用于需要高质量配图、素材生成、本地私密生图、或对在线生成有频率限制的场景。

触发时机

在以下场景时使用:

  • 用户/其他 agent 说"本地生图"、"本地SD生图"、"用本地工具生成图片"
  • 用户/其他 agent 说"私密生图"、"脱敏生图"、"不上传在线"
  • 需要生成涉及隐私、测试、商业素材的内容,且明确指定本地处理
  • 需要精细控制构图、风格、尺寸的生图任务,且指定本地执行

不要用于:

  • 默认生图请求(那些默认走在线服务,如 Midjourney/DALL-E)
  • 用户说"生成图片"、"画一张图"且没有指定本地(默认在线优先)

使用方式

直接描述想要的图片内容,例如:

  • "帮我生成一张科技感十足的封面图"
  • "画一个程序员深夜编程的场景,插画风格"
  • "生成一张杭州西湖的夜景图,高清写实风格"

Agent 收到后执行生图脚本,发送结果给用户。

技术规格

项目参数
模型Stable Diffusion XL 1.0 (fp16)
显卡NVIDIA RTX 3080 (10GB VRAM)
出图尺寸默认 1024×768,可调整
生图速度~18秒/张(euler 采样,20步)
可用采样器euler, dpmpp_2m, lcm, ddim 等
API 端口localhost:8188

Agent 调用方法

方式一:通过脚本调用(推荐)

import subprocess
result = subprocess.run(
    ["python3", "/path/to/scripts/sdxl_generate.py",
     "--prompt", "一只狐狸在森林里",
     "--negative", "模糊, 低质量",
     "--steps", "20",
     "--seed", "42",
     "--output", "/tmp/output.png"],
    capture_output=True, text=True
)
print(result.stdout)

方式二:直接调 ComfyUI REST API

import requests, time, json

COMFYUI = "http://localhost:8188"

def generate(prompt, negative="", steps=20, seed=42, width=1024, height=768):
    workflow = {
        "loader": {"class_type": "CheckpointLoaderSimple",
                   "inputs": {"ckpt_name": "sdxl-base-1.0.safetensors"}},
        "positive": {"class_type": "CLIPTextEncode",
                     "inputs": {"text": prompt, "clip": ["loader", 1]}},
        "negative": {"class_type": "CLIPTextEncode",
                      "inputs": {"text": negative, "clip": ["loader", 1]}},
        "latent": {"class_type": "EmptyLatentImage",
                   "inputs": {"width": width, "height": height, "batch_size": 1}},
        "sampler": {"class_type": "KSampler",
                    "inputs": {"seed": seed, "steps": steps, "cfg": 7.0,
                               "sampler_name": "euler", "scheduler": "normal",
                               "denoise": 1.0,
                               "positive": ["positive", 0], "negative": ["negative", 0],
                               "model": ["loader", 0], "latent_image": ["latent", 0]}},
        "decode": {"class_type": "VAEDecode",
                   "inputs": {"samples": ["sampler", 0], "vae": ["loader", 2]}},
        "save": {"class_type": "SaveImage",
                 "inputs": {"images": ["decode", 0], "filename_prefix": "sdxl_gen"}}
    }
    r = requests.post(f"{COMFYUI}/prompt", json={"prompt": workflow})
    pid = r.json()["prompt_id"]
    # 等待完成(轮询)
    for _ in range(30):
        time.sleep(2)
        hist = requests.get(f"{COMFYUI}/history/{pid}").json()
        if pid in hist:
            return f"{COMFYUI}/view?filename=sdxl_gen_00001_.png"
    return None
