最佳实践

照片输入提示

• 清晰显示面部：确保光线充足，面部清晰可见
• 优先选择正面照：正面或略带角度的照片效果最佳
• 分辨率要高：输入分辨率越高，输出质量越好
• 背景简洁：简单的背景有助于突出主体

头像提示词技巧

1. 明确指定风格：卡通、3D、写实、anime 等
2. 描述期望的特征：光线、表情、姿势
3. 注明平台：LinkedIn、Instagram、游戏平台——这会影响优化方式
4. 说明背景偏好：影棚、渐变、主题背景等
5. 要求保持一致性：生成多个头像时，使用 session_id 并参考之前的输出

风格一致性

为同一个人创建多个头像时：

• 使用 session_id 在多个请求之间保持上下文
• 请求新姿势时参考之前的生成结果
• 明确说明需要保持一致的特征

模式选择

生成前先询问用户：

“您想要快速且便宜，还是高质量？”

模式	最适用场景	速度	质量
max	最终头像、专业头像照、精细的奇幻角色	较慢	最高
eco	快速预览、探索风格、批量生成变体	较快	良好

多轮头像优化

使用 session_id 迭代并优化你的头像：

# Initial avatar
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 a professional avatar from this photo"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "my-avatar-project",
    "image_urls": ["https://example.com/my-photo.jpg"]
  }'

# Refine based on feedback
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": "Make the lighting warmer and add a slight smile"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "my-avatar-project"
  }'

# Try a different style
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": "Can you make a cartoon version of this same avatar?"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "my-avatar-project"
  }'

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	确保照片和提示词符合内容政策
超时	生成过程复杂	将客户端超时设置为至少 10 分钟
相似度较低	输入质量较差	使用分辨率更高、光线充足且面部清晰的照片
