最佳实践

选择放大倍数

• 2 倍：足以满足大多数网页和社交媒体用例
• 4 倍：印刷质量的标准选择（相当于 300 DPI）
• 8 倍以上：仅适用于观看距离较远的大幅面场景

质量提示

• 源图像质量很重要：输入质量越高，放大后的输出效果越好
• 文件格式：尽可能使用 PNG 或高质量 JPEG（90% 以上）作为输入
• 面部增强：仅对包含人脸的图像启用
• 降噪：用于低光照或严重压缩的图像时，可大幅启用降噪

输出注意事项

• 文件大小：放大倍数越高，生成的文件就越大
• 处理时间：8 倍和 16 倍放大需要更长时间，请耐心等待
• 观看距离：大幅面印刷品通常会从远处观看，并非总是需要极致细节

图像放大的提示词技巧

请求放大时，请在提示词中包含以下详细信息：

1. 放大倍数：指定 2 倍、4 倍、8 倍或 16 倍
2. 用例：网页、印刷、大幅面显示
3. 图像类型：照片、AI 艺术作品、产品图、人像
4. 特殊要求：面部增强、降噪、伪影去除
5. 输出用途：最终用途有助于优化处理效果

提示词结构示例

"Upscale this [image type] [scale factor] for [use case].
[Special requirements like face enhancement or noise reduction].
[Additional context about the source image quality or intended output]."

模式选择

处理前询问用户：

“您想要速度快、成本低，还是质量高？”

模式	最适合	速度	质量
max	最终成品图、印刷材料、重要项目	较慢	最高
eco	快速预览、批量测试、网页缩略图	较快	良好

多轮放大工作流

使用 session_id 迭代调整放大结果：

# Initial upscale
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": "Upscale this photo 4x for print"}],
    "model": "eachsense/beta",
    "stream": true,
    "image_urls": ["https://example.com/photo.jpg"],
    "session_id": "upscale-project-001"
  }'

# Request adjustments
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": "The result looks good but can you also apply face enhancement and reduce noise?"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "upscale-project-001"
  }'

# Request different scale
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": "Actually I need 8x for a larger print. Can you upscale it further?"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "upscale-project-001"
  }'

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
图像过大	源图像超出最大尺寸	放大前调整源图像尺寸
超时	较大的缩放倍数需要更长时间	将客户端超时时间设为至少 10 分钟
不支持的格式	图像格式无效	使用 JPEG、PNG 或 WebP 输入
