Grok Build’s /deep-research command is one of the most useful tools in Grok Build Most AI research still works like this: You ask a question It searches It writes a long answer You hope the sources are solid /deep-research works differently Instead of dumping a single pass of notes, it runs a structured background research workflow: • Plans a bounded set of questions around your topic • Gathers structured claims with source evidence • Cross-checks every claim on an independent verifier • Keeps only the claims that survive verification • Attaches verified source locators to what remains If something fails, gets dropped, or stays uncertain, it does not quietly hide that It reports those gaps as coverage limitations and marks the report Partial when anything remains unresolved That honesty is the point You are not getting a confident-sounding essay You are getting a filtered research report where surviving claims had to pass a second check
