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:
Max subscribers get Opus 4.6 Thinking
Pro subscribers get 4.5 Thinking gradually
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
Deep Research is designed for knowledge workers, researchers, and students who need in-depth analysis. It adapts its depth, tone, and format based on the type of work being done—whether that's writing a thesis, preparing a market analysis, or exploring a complex topic.
