Proven Autonomous Research Workflows
Click on any workflow below to view its dedicated architecture breakdown, flowcharts, benchmarks, and implementation patterns:
Stanford STORM
Perspective-guided outline induction, simulated expert persona interviews, and section-by-section isolated drafting (Map-Write) to achieve +25% structural flow.
LangGraph StateGraph
Cyclical directed state graphs with TypedDict deterministic reducers, upfront human scoping clarification, and dynamic reflection nodes that evaluate research saturation.
Frontier Reasoning Agents
Long-horizon autonomous execution (15–45 min), test-time recursive tree search (MCTS), dynamic contradiction backtracking, and sandboxed Python code execution.
Antigravity Parallel-Search v2
Harmonized production engine featuring 5-tier resilient scraping (Patchright CDP bypass), strict JSON distillation, Wave 2 Devil's Advocate Critic, and 4-factor calibrated scoring.
Multi-Dimensional Capability Radar
Evaluating the 4 proven research architectures across the 6 vital axes of real-world information retrieval:
Architectural Comparison Matrix
