最佳实践

参考照片指南

• 数量：提供 3-10 张参考照片，以获得最佳效果
• 角度：尽可能包含正面、3/4 侧面和侧面视图
• 光线：使用光线充足、没有强烈阴影的照片
• 分辨率：分辨率越高，生成的数字孪生效果越好
• 一致性：照片应展示同一个人，且年龄相近
• 表情：加入多种表情，以生成富有表现力的数字孪生

质量优化

• 模式选择：最终素材使用 max，快速原型制作使用 eco
• 迭代优化：使用 session_id，通过多次请求优化数字孪生
• 具体细节：准确描述光线、背景和表情要求
• 格式说明：始终指定宽高比和预期用途

身份一致性

• 会话连续性：同一个数字分身的所有变体都使用相同的 session_id
• 参考锚定：请求生成变体时附上原始照片
• 风格锁定：描述各次请求中保持一致的元素（光线、背景）

模式选择

生成前询问用户：

“你想要速度快、成本低，还是质量高？”

模式	最适合	速度	质量
max	最终数字分身、生产素材	较慢	最高
eco	快速预览、探索概念	较快	良好

多轮数字分身开发

使用 session_id 迭代开发和优化数字分身：

# Initial twin generation
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \

    "mode": "max",
    "session_id": "ceo-digital-twin"
  }'

# Refine based on feedback
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \

    "model": "eachsense/beta",
    "stream": true,
    "session_id": "ceo-digital-twin"
  }'

# Generate variations
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create 3 variations with different backgrounds: 1) Modern office, 2) Gradient blue, 3) Pure white"}],
    "model": "eachsense/beta",

  }'

错误处理

错误	原因	解决方案
Failed to create prediction: HTTP 422	余额不足	在 eachlabs.ai 充值
内容政策违规	内容被禁止	确保照片已获得适当授权
超时	生成内容过于复杂	将客户端超时设置为至少 10 分钟
输出质量低	参考照片质量差	提供质量更高、光线更好的照片
