GLM Vision - 图片分析技能

概述

使用智谱 GLM-4.6V 多模态模型分析图片内容。支持:

  • 图片内容描述和理解
  • 图片中的文字提取(OCR)
  • 图片元素识别和分析
  • 多图对比分析
  • 视频内容理解

使用场景

当用户发送图片并提出以下类型问题时触发:

  • "这张图片里有什么?"
  • "请描述这张图片"
  • "分析这个截图"
  • "这是什么?"
  • "图片里的文字是什么?"
  • "比较这两张图片"

API 配置

环境变量

需要设置 ZHIPU_API_KEY 环境变量:

export ZHIPU_API_KEY="your-api-key-here"

或者在 ~/.claude/settings.json 中配置:

{
  "env": {
    "ZHIPU_API_KEY": "your-api-key-here"
  }
}

模型选择

模型用途价格
glm-4.6v-flash免费版,日常使用免费
glm-4.6v旗舰版,复杂推理付费
glm-4.6v-flashx轻量高速版付费

默认使用 glm-4.6v-flash 免费模型。

调用方式

方式一:使用辅助脚本(推荐)

python3 ~/.claude/skills/glm-vision/scripts/analyze_image.py \
  --image "/path/to/image.jpg" \
  --prompt "请描述这张图片" \
  [--model "glm-4.6v-flash"]

参数说明:

  • --image / -i: 图片路径(支持 URL 或本地文件)
  • --prompt / -p: 分析提示词
  • --model / -m: 模型名称(可选,默认免费版)
  • --detail / -d: 启用详细思考模式

方式二:直接 API 调用

import base64
from openai import OpenAI

client = OpenAI(
    api_key=os.environ.get("ZHIPU_API_KEY"),
    base_url="https://open.bigmodel.cn/api/paas/v4"
)

# 读取本地图片
with open("image.jpg", "rb") as f:
    img_base64 = base64.b64encode(f.read()).decode("utf-8")

response = client.chat.completions.create(
    model="glm-4.6v-flash",
    messages=[{
        "role": "user",
        "content": [
            {"type": "image_url", "image_url": {"url": img_base64}},
            {"type": "text", "text": "请描述这张图片"}
        ]
    }]
)
print(response.choices[0].message.content)

方式三:URL 图片

response = client.chat.completions.create(
    model="glm-4.6v-flash",
    messages=[{
        "role": "user",
        "content": [
            {"type": "image_url", "image_url": {"url": "https://example.com/image.jpg"}},
            {"type": "text", "text": "分析这张图片"}
        ]
    }]
)

工作流程

  1. 接收图片: 用户发送图片,保存到临时目录
  2. 构建请求: 将图片转为 base64 或使用 URL
  3. 调用 API: 发送到 GLM-4.6V 模型
  4. 返回结果: 解析并展示分析结果

支持的图片格式

  • JPEG / JPG
  • PNG
  • GIF(静态)
  • WebP
  • BMP

示例用法

基础图片描述

python3 ~/.claude/skills/glm-vision/scripts/analyze_image.py \
  -i "/tmp/screenshot.png" \
  -p "描述这张截图的内容"

详细分析

python3 ~/.claude/skills/glm-vision/scripts/analyze_image.py \
  -i "/tmp/photo.jpg" \
  -p "分析这张图片的构图、色彩和主题" \
  --detail

OCR 文字提取

python3 ~/.claude/skills/glm-vision/scripts/analyze_image.py \
  -i "/tmp/document.png" \
  -p "提取图片中的所有文字,保持原有格式"

URL 图片分析

python3 ~/.claude/skills/glm-vision/scripts/analyze_image.py \
  -i "https://example.com/image.jpg" \
  -p "这张图片展示的是什么?"

注意事项

  1. API Key 安全: 不要在代码中硬编码 API Key
  2. 图片大小: 建议图片小于 10MB,过大的图片会增加延迟
  3. 网络连接: 需要稳定的网络访问智谱 API
  4. 并发限制: 免费用户并发数为 5
