Understanding Providers
This page explains how different providers work and when to use each one.
What is a "Deep Research" Provider?
Traditional AI chatbots answer questions from their training data. Deep research providers go further:
- Search the web for current information
- Read and synthesize multiple sources
- Provide citations for their claims
- Generate comprehensive reports rather than brief answers
How Providers Differ
Data Sources
| Provider | Primary Sources |
|---|---|
| OpenAI | Web search, multiple domains |
| Perplexity | Real-time web, news, forums |
| Edison | Scientific papers (via PaperQA3) |
| Consensus | Peer-reviewed academic papers only |
Research Depth
Shallow (seconds): Quick web search, summarize top results
- Perplexity sonar
- Consensus
Medium (30s - 2min): More thorough search, cross-reference sources
- Perplexity sonar-pro
Deep (2-15min): Extensive research, iterative refinement, comprehensive synthesis
- OpenAI o3
- Perplexity sonar-deep-research
- Edison
Citation Quality
Best for academic citations:
- Consensus - only peer-reviewed papers
- Edison - scientific literature focus
Best for web citations:
- Perplexity - good source attribution
- OpenAI - comprehensive but less consistent formatting
OpenAI Deep Research
OpenAI's approach uses their o3/o4 models with web browsing capabilities.
How it works:
- Formulates search queries based on your question
- Browses multiple web pages
- Synthesizes information across sources
- Generates a comprehensive report
Strengths:
- Most thorough analysis
- Can interpret code and data
- Excellent synthesis across diverse topics
Limitations:
- Slowest option (5-15 minutes)
- Most expensive
- May have access restrictions on some sites
Perplexity AI
Perplexity combines LLM reasoning with real-time web search.
How it works:
- Parses your query into search intents
- Performs web searches
- Reads and extracts relevant content
- Synthesizes with source attribution
Three tiers:
- sonar: Fast, basic web search
- sonar-pro: More thorough, better reasoning
- sonar-deep-research: Extensive multi-step research
Strengths:
- Multiple speed/quality options
- Good at current events
- Transparent citations
Limitations:
- Deep research mode can be slow
- Quality varies by topic
Edison Scientific (Falcon)
Edison (formerly FutureHouse Falcon) specializes in scientific literature.
How it works:
- Powered by PaperQA3 - an AI system designed for scientific papers
- Searches scientific databases
- Reads full paper content (not just abstracts)
- Synthesizes findings with proper academic citations
Strengths:
- Deep scientific literature coverage
- Full paper analysis, not just abstracts
- Good for biomedical and technical research
Limitations:
- Slower than general web search
- Less useful for non-scientific topics
- May miss very recent papers
Consensus
Consensus focuses exclusively on peer-reviewed research.
How it works:
- Searches a curated database of academic papers
- Extracts findings relevant to your question
- Provides evidence-based summaries
- Only cites peer-reviewed sources
Strengths:
- Only peer-reviewed sources
- Good for "does X cause Y" type questions
- Fast responses
Limitations:
- Limited to their indexed papers
- Not comprehensive for obscure topics
- Can't access recent papers quickly
Combining Providers
For thorough research, use multiple providers:
# Quick overview
deep-research-client research "topic" --provider perplexity --model sonar
# Scientific depth
deep-research-client research "topic" --provider edison
# Academic consensus
deep-research-client research "topic" --provider consensus
# Comprehensive synthesis
deep-research-client research "topic" --provider openai
Cost vs Quality Trade-offs
The relationship between cost and quality isn't always linear:
Best value for general queries: Perplexity sonar-pro - good quality at moderate cost
Best value for academic queries: Consensus - low cost, high-quality academic sources
When to pay premium: Use OpenAI o3 when you need the most thorough analysis and can wait 10+ minutes
