In 2026, the AI search engine Perplexity has fundamentally changed how information retrieval works. Its latest Sonar Pro model has achieved an F-score of 0.858 on the SimpleQA benchmark — the highest factuality score in the industry. Deep Research mode automatically generates expert-level investigation reports from hundreds of sources. Integration with GPT-5.2, Claude 4.5, and Gemini 3 allows users to select the best AI model for any given query.
This article covers Perplexity's 2026 feature set, pricing, competitive comparisons, and practical business applications.

Sonar: The Engine at the Core
What Sonar Does
Sonar is Perplexity's proprietary search-optimized AI model. Built on Llama 3.3 70B with fine-tuning focused on factuality and readability, it combines real-time web search with structured citation output.
Sonar's strengths:
- Cerebras infrastructure: Generates 1,200 tokens per second
- Real-time web search: Always pulling from current information
- Citation by claim: Every assertion is sourced
- Domain filtering: Restrict searches to specific sites
Sonar Pro: Industry-Leading Factuality
Sonar Pro is Perplexity's flagship model.
SimpleQA Benchmark (January 2026):
| Model | F-score |
|---|---|
| Sonar Pro | 0.858 |
| Sonar | 0.773 |
| GPT-4o | 0.720 |
| Claude 3.5 Sonnet | 0.695 |
Sonar Pro's top ranking on SimpleQA comes from combining strong LLM reasoning with real-time web retrieval. Rather than answering from training data alone, it verifies claims against live web sources — which is why its factuality outperforms models with larger parameter counts.
Deep Research: Expert-Level Investigation on Demand
What Deep Research Does
Deep Research is Perplexity's most powerful feature. Rather than answering a single question, it conducts multi-step investigations across hundreds of sources and generates a structured report automatically.
Deep Research characteristics:
- Multi-step reasoning process
- Information gathered from 100+ sources
- Structured report format (table of contents, sections, tables)
- Detailed analysis with 40+ citations
Deep Research in Practice
Example: "Analyze EV market trends for 2026"
Deep Research output:
- 3-page structured document
- Sectioned by topic (market size, key players, technology trends, challenges)
- Data tables (sales figures by manufacturer, market share)
- 40+ citations (research reports, news articles, company announcements)
The research a human analyst would spend hours or days completing, Deep Research delivers in minutes.
Deep Research Pricing
| Item | Price |
|---|---|
| Input tokens | $3 / 1M tokens |
| Output tokens | $15 / 1M tokens |
| Typical query | ~$0.41 |
