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

```bash
# 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"}]}'

```
