Perplexity深度搜索

具备三种模式、支持不同深度级别的AI驱动网络搜索。

快速开始

# Quick search (sonar) - facts, summaries, current events
{baseDir}/scripts/search.sh "latest AI news"

# Reasoning (sonar-reasoning-pro) - complex analysis, multi-step
{baseDir}/scripts/search.sh --mode reason "compare React vs Vue for enterprise apps"

# Deep Research (sonar-deep-research) - full reports, exhaustive analysis
{baseDir}/scripts/search.sh --mode research "market analysis of AI in healthcare 2025"

模式

选项

示例

# Search with recency filter
{baseDir}/scripts/search.sh --recency week "OpenAI latest announcements"

# Search restricted to specific domains
{baseDir}/scripts/search.sh --domains "arxiv.org,nature.com" "transformer architecture advances"

# Search in Portuguese
{baseDir}/scripts/search.sh --lang pt "inteligência artificial no Brasil"

# Deep research with JSON output
{baseDir}/scripts/search.sh --mode research --json "enterprise AI adoption trends"

API密钥

设置PERPLEXITY_API_KEY环境变量，或将其存储在文件中：

mkdir -p ~/.config/perplexity
echo "your_key_here" > ~/.config/perplexity/api_key
chmod 600 ~/.config/perplexity/api_key

脚本会先检查环境变量，然后回退到文件。

价格参考

• 搜索（sonar-pro）：约$0.01/次查询
• 推理（sonar-reasoning-pro）：约$0.02/次查询
• 深度研究（sonar-deep-research）：约$0.40/次查询（使用多次搜索 + 推理）

使用搜索用于日常查询。保留研究用于真正需要详尽分析时。
