Question: Who has a “research agent” among Claude, ChatGPT, Gemini, etc.?

Answer:

Most frontier AI labs now have some form of research agent / deep research mode. The idea is similar: the model does not just answer from its weights; it performs a multi-step workflow:

User question
      |
      v
Planner agent
      |
      +--> Search web / papers / docs
      |
      +--> Read sources
      |
      +--> Extract facts
      |
      +--> Verify contradictions
      |
      +--> Write report with citations

Main players:

Company Product Research agent capability
OpenAI ChatGPT Deep Research One of the most advanced general research agents
Anthropic Claude Research (via Claude.ai features) Strong at long documents + analysis
Google Gemini Deep Research Strong because of Google Search integration
Perplexity Deep Research Built around search + answer synthesis
xAI Grok DeepSearch Web research focused
Microsoft Copilot Researcher Enterprise research workflows
Alibaba Qwen deep research features Open-source ecosystem experiments
DeepSeek Deep research style agents via ecosystem More community-driven

1. OpenAI ChatGPT Deep Research

Architecture is close to:

GPT model
+
browser/search tools
+
code execution
+
citation system
+
long-context reasoning

Typical use:

It can spend minutes researching instead of generating immediately.


2. Claude Research

Claude’s advantage:

A common workflow:

100 papers PDF
        |
        v
Claude
        |
        v
Research map
        |
        v
Literature review

For example:

“Read these 50 ML papers and identify research gaps.”

Claude is often very good here.


3. Gemini Deep Research

Google has a natural advantage:

Gemini
   |
Google Search
   |
Google Scholar
   |
YouTube
   |
Gmail/Drive (enterprise)

Especially strong for:


4. Perplexity Deep Research

Perplexity is almost a research-native product.

Its core loop:

Question
 |
Search dozens of pages
 |
Rank sources
 |
Summarize
 |
Cite

Very good for:


The interesting future: multi-agent research

The future is probably not:

one giant model answers

but:

Research Manager Agent

Final Research Report

Example:

GPT-5 Agent:
  "Study whether RTX 3090 clusters are viable for LLM training"

Agent A:
  collect hardware benchmarks

Agent B:
  collect papers

Agent C:
  calculate economics

Agent D:
  challenge assumptions

Final:
  50-page engineering report

This is very close to how human research teams work.

Given your experiments with multiple models (Claude + GPT + Gemini cross-validation), the interesting direction is actually:

10 frontier models
100 specialized agents
1 research organization

where models become “research employees”:

The bottleneck becomes orchestration, not raw intelligence.
