Architectural Comparison Matrix

Evaluation Parameter Stanford STORM LangGraph Open Deep Research Frontier Reasoning (o3 / Gemini) Antigravity Parallel-Search v2
Pre-Search Decomposition Simulated expert personas & multi-turn interviews ScopingNode with user ambiguity clarification Dynamic sub-goal formulation via Chain-of-Thought Perspective Engine + 4-Vector Query Matrix
Execution Topology Outline-first hierarchical DAG ($H_1 \to H_3$) Cyclical StateGraph with reflection loops Recursive tree search with MCTS backtracking Outline Wave DAG + Wave 2 Critic Gate
Token Efficiency Section-level context isolation TypedDict state reducers Subagent log pruning Strict JSON Distillation (>85% reduction)
Anti-Bot & Scraping Defense None (Standard HTTP GET) External API provider (Tavily/Exa) Proprietary cloud sandbox 5-Tier Cascade (Patchright Stealth Browser)
Adversarial Validation Multiple persona viewpoints Reflection node gap check Chain-of-Thought contradiction checks Popperian Devil's Advocate Critic Agent
Citation Integrity Direct citation-to-outline node mapping Structured JSON URL anchors Traceable verbatim text spans 3-Layer Audit (URL 200 + NLI Entailment)
Cost & Latency Moderate (3–6 min, $0.20) Moderate (3–7 min, $0.25) High (15–45 min, $2.00–$8.00) Low/Fast (2–4 min, $0.08 via Flash workers)
