Session constraints
One active session at a time
Only one Deep Research session can run at a time per account. If you attempt to start a new session while one is already in progress, ZeroTwo will prompt you to confirm whether to cancel the current session.- Canceling an in-progress session consumes the research credit — the partial session counts toward your daily limit even if no report was delivered
- To avoid wasting credits, let the current session finish before starting a new one, or wait until you are ready to fully commit to the new topic
Session isolation
Each Deep Research session is independent:- A session is tied to the specific chat thread where it was started
- You cannot merge findings from two separate sessions automatically — but you can reference or paste content from one report into a follow-up chat
Time to complete
Deep Research typically takes 2–10 minutes to deliver a completed report. The actual time depends on several factors:| Factor | Effect on duration |
|---|---|
| Number of research areas in the plan | More topics = longer research |
| Depth of each topic | More subtopics and sub-questions = longer |
| Amount of source material available | Dense topics with many sources take longer to synthesize |
| Server load during peak usage | May add a small amount of additional latency |
You will see a live progress indicator in the chat showing what ZeroTwo is currently doing — searching, reading a specific URL, or synthesizing. This gives you a real-time sense of how far along the session is.
What affects source coverage
Deep Research is powered by Firecrawl, which crawls web content more comprehensively than a standard search engine query. For each topic in the research plan, Firecrawl:- Retrieves and fully reads relevant pages (not just previews or snippets)
- Follows links within relevant pages to discover additional sources
- Processes multiple source types: articles, research papers, reports, PDFs, company pages
- Publicly accessible web pages: yes
- Paywalled content or pages requiring a login: no
- Very recently published pages not yet indexed: may be missed
- Pages that block web crawlers via
robots.txt: no
Running in the background
Deep Research runs server-side — closing the tab or navigating away does not stop it.- If you close the tab mid-research, the session continues on ZeroTwo’s servers
- Return to the same chat thread to find the completed report when it finishes
- If your browser session expired while research was running, log back in and navigate to the chat thread — the report will be waiting
No pausing mid-run
Currently, active research cannot be paused once it has started. Use the plan review step to fully scope and adjust your research before approving — that is the last checkpoint before the automated crawl begins. If you realize mid-run that the plan was wrong:- You can let it complete and then use follow-up prompts to reshape the report
- Or cancel the session and start fresh with a better-scoped prompt (this uses an additional credit)
