Deep Research Mode With Iterative Refinement

via “multi-step reasoning search with iterative refinement”

AI search engine — direct answers with citations, Pro Search, Focus modes, research Spaces.

Unique: Implements explicit query decomposition and iterative refinement where the model generates its own follow-up searches based on intermediate results, rather than executing a single retrieval pass. This mirrors human research behavior (asking follow-up questions based on initial findings) and is architecturally distinct from single-pass RAG systems that retrieve once and generate once.

vs others: Outperforms single-pass search engines and basic RAG systems on complex research questions by dynamically identifying information gaps and filling them, whereas Google Search requires manual query reformulation and ChatGPT lacks real-time web access for iterative refinement.

via “research mode selection and workflow adaptation”

Autonomous agent for comprehensive research reports.

Unique: Implements mode-specific workflow orchestration through the ResearchConductor, which adjusts LLM model tier, context compression, and multi-agent iteration counts per mode. This allows a single codebase to serve both fast-and-cheap and thorough-and-expensive research use cases.

vs others: More flexible than fixed-pipeline competitors because mode selection allows users to trade off speed, cost, and quality; more transparent than black-box research tools because mode parameters are explicit and configurable.

Unique: Implements iterative research through agent-driven web search with semantic deduplication and confidence-based loop termination, allowing the system to autonomously refine search queries based on gaps in previous results. Integrates web search results directly into the agent loop for synthesis and follow-up query generation.

vs others: Provides autonomous iterative research with gap detection and source tracking, whereas Perplexity and similar tools perform single-pass searches without iterative refinement or explicit confidence metrics.

via “research mode adaptation with standard/detailed/deep configurations”

An autonomous agent that conducts deep research on any data using any LLM providers

Unique: Implements three explicit research modes (standard/detailed/deep) with mode-specific adjustments to context limits, sub-query count, and revision cycles, rather than single-mode research. Modes are declaratively configured through Config class.

vs others: More flexible than single-mode research because it enables depth control without code changes, and more transparent than automatic depth selection because users explicitly choose their quality-cost tradeoff.
