Improved Research Quality
Advanced Deep Research delivers more comprehensive and accurate reports. We've tested it against industry benchmarks, where it matches or outperforms competitors on tasks including fact-finding, product comparisons, academic research, and professional due diligence.
The update focuses on depth. Advanced Deep Research searches more sources, cross-references information, and produces reports suited for professional work.
Expanded Capabilities
Deep Research can now:
-
Run calculations and analyze data with an improved code sandbox
-
Process and work with uploaded documents directly
-
Browse more of the web to find information from harder-to-reach sources
These additions handle tasks that previously required manual work.
Which Models Are Used
All subscribers now use our most capable models with Deep Research:
-

Usage limits have been adjusted to allocate more computing power per session, so you get deeper insights and higher-quality results.
What Else Is New
Deep Research has a new user experience:
-
Clarifying questions
For broad queries, Research now asks clarifying questions before starting—helping deliver relevant results on the first attempt.
-
Follow-up questions during research
You can add follow-up questions while research is still running, rather than waiting for completion.
-
See Research Progress
A new progress display shows which sources are being read, what's being learned, and how the report is coming together.
-
Key Findings as You Go
Key findings appear as research progresses, so you can start reviewing information before the final report is ready.
-
Reports You Can Edit and Share
Your research reports now stream directly into a file, where you can edit, refine, and share them.
When to Use Deep Research
