Sonar Deep Research — Async Mode and Reasoning Effort Now Live

Announcements
1

Sonar deep research just got a big upgrade:

  • Async mode is now live — submit long-running deep research requests via POST /v1/async/sonar and poll for results, no more connection timeouts
  • Reasoning effort control — tune how much thinking the model does with the reasoning_effort parameter (minimal, low, medium, high)
  • Academic mode on all models — use search_mode: "academic" to prioritize scholarly sources
  • Richer citations — every citation now includes title, URL, and date
# Submit async deep research
curl -X POST https://api.perplexity.ai/v1/async/sonar \
  -H "Authorization: Bearer $PERPLEXITY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "sonar-deep-research", "messages": [{"role": "user", "content": "Your research query"}]}'
