Orchestrates end-to-end research workflows by decomposing user queries into parallel sub-queries, executing them concurrently across multiple LLM providers, and synthesizing results into structured reports. Uses a planner-executor agent pattern where the planner decomposes tasks and the executor conducts parallel research, inspired by Plan-and-Solve and RAG papers. The ResearchConductor class manages the workflow state, skill invocation sequencing, and context compression across research phases.
Unique: Implements a three-tier LLM strategy (planner, executor, writer) with explicit query decomposition and parallel sub-query execution, rather than sequential search-and-summarize. The ResearchConductor manages skill invocation order and context compression, enabling structured multi-step workflows that adapt to different research modes (standard/detailed/deep) with configurable depth.
vs alternatives: Faster than sequential research tools (Perplexity, traditional RAG) because it parallelizes sub-query execution across multiple LLM calls simultaneously, and more structured than generic LLM agents because it uses explicit workflow orchestration with skill managers rather than free-form tool calling.
Abstracts 25+ LLM providers (OpenAI, Anthropic, Ollama, Groq, etc.) behind a unified interface using a three-tier strategy: planner LLM (query decomposition), executor LLM (research execution), and writer LLM (report generation). Implements provider-specific prompt formatting, token limits, and capability detection. The Config class manages provider selection, fallback chains, and model-specific parameters like temperature and max_tokens, enabling seamless provider swapping without code changes.
Unique: Implements explicit three-tier LLM strategy (planner/executor/writer) with per-tier provider selection, rather than single-provider abstraction. Includes model-specific handling for token limits, prompt formatting, and capability detection, enabling fine-grained control over which provider handles which research phase.
vs alternatives: More flexible than LangChain's LLM abstraction because it allows different providers per research phase and includes explicit fallback chains, and more cost-effective than single-provider solutions because it enables mixing cheap planners with expensive executors.
Exposes GPT Researcher as an MCP server, enabling integration with any MCP-compatible client (Claude, other AI assistants, custom tools).

Supports configuration inheritance and defaults, enabling easy switching between development/staging/production environments. Configuration validation ensures required parameters are set before research execution.
Unique: Implements hierarchical configuration system supporting environment variables, files, and programmatic overrides with validation, rather than hardcoded settings. Enables environment-specific configuration without code changes.
vs alternatives: More flexible than hardcoded settings because it supports multiple configuration sources, and more robust than simple env var parsing because it includes validation and inheritance.
Executes parallel web scraping and document retrieval across multiple sources (web search, local documents, cloud storage) using a pluggable Retriever system. The web scraping module uses browser automation (Playwright/Selenium) to handle JavaScript-heavy sites, while document loaders support PDF, DOCX, TXT, and other formats. Sources are deduplicated, ranked by relevance, and filtered by domain constraints before being passed to the research pipeline. The system supports cloud storage integration (S3, GCS) for document sources.
Unique: Implements pluggable Retriever system supporting web search, local documents, and cloud storage with parallel execution and source deduplication. Uses browser automation for JavaScript-heavy sites rather than simple HTTP requests, enabling research on dynamic content. Includes domain filtering and source curation before ranking.
vs alternatives: More comprehensive than simple web search because it integrates documents and cloud storage, and faster than sequential retrieval because it parallelizes requests across sources.
