UnverifiedOptimist Deep Research is an open-source project that proposes an iterative evidence-acquisition approach centered on an explicit, mutable research state.75% similarUnverifiedThe core difference between Deep Research and single-pass retrieval Q&A lies in iterative reasoning, where each round of search results updates the agent's understanding of the problem and generates a more precise query for the next round.74% similarUnverifiedPerplexity officially states that the Computer agent is grounded in accurate deep research.67% similarUnverifiedOptimist Deep Research's search intents are translated into specific queries targeting arXiv, OpenAlex, Crossref, PubMed, Semantic Scholar, and the open web.67% similarVerifiedThe Deep Research feature decomposes a single user query into multi-step autonomous research tasks, invokes tools such as web search and document analysis, and uses large language model reasoning to synthesize and output a structured report.66% similar
