NexusAI 🧠

Multi-Agent Autonomous Research & Decision Intelligence System

"From raw data to actionable decisions — fully autonomous."

The Problem

Every organization drowns in data but starves for decisions.

Current AI tools answer single questions. They don't:

• Connect dots across 50 sources simultaneously
• Reason through multi-step problems autonomously
• Collaborate between specialized agents to cross-validate findings
• Deliver a final decision with full reasoning trace

NexusAI solves this. It deploys a coordinated swarm of specialized AI agents that research, reason, debate, and converge on high-confidence decisions — without human hand-holding.

Agent Roles

Agent	Role	Capability
Orchestrator	Task decomposition	Breaks complex goals into parallel subtasks
Research Agent	Data gathering	Web search, RAG, document parsing
Analyst Agent	Chain-of-thought reasoning	Multi-step inference, pattern detection
Validator Agent	Critique & fact-check	Cross-validates claims, flags contradictions
Synthesis Agent	Final output	Merges findings into structured decision report

---

Key Features

• Long-chain reasoning — Analyst agent uses CoT (Chain-of-Thought) with up to 32 reasoning steps
• Multi-agent debate — Validator challenges Analyst findings before synthesis
• Persistent memory — Vector store (ChromaDB) for cross-session context retention
• Tool use — Web search, code execution, file parsing, API calls
• Streaming output — Real-time reasoning trace visible to user
• REST API — Drop-in integration for any product

Quickstart

git clone https://github.com/Sicanbt/NexusAI.git
cd NexusAI
pip install -r requirements.txt
cp .env.example .env  # add your API keys
python -m nexus run "Analyze the top 5 AI infrastructure companies and recommend the best investment target"

Example Output

[ORCHESTRATOR] Breaking task into 3 subtasks...
[RESEARCH]     Fetching data on NVIDIA, CoreWeave, Lambda Labs, Together AI, Groq...
[ANALYST]      Step 1: Revenue growth analysis...
               Step 2: Moat assessment...
               Step 8: Risk-adjusted scoring...
[VALIDATOR]    Challenging claim: "CoreWeave has strongest moat"...
               Counter-evidence found. Flagging for re-analysis.
[ANALYST]      Revising conclusion based on validator feedback...
[SYNTHESIS]    Final recommendation: [NVIDIA] — confidence 87%
               Full reasoning trace: 847 tokens
