	## 🎯 Overview

	A production-ready dual-pipeline GraphRAG system that works with any LLM — from GPT-4o to Claude to a local Llama running on your laptop via Ollama. Ships with:

	- 12 LLM providers through a single universal interface (zero per-provider SDKs)
	- OpenClaw autonomous agent integration — GraphRAG as native Skills
	- Ollama local model support — run completely free, no API keys needed
	- Next.js 15 web dashboard with TigerGraph × Claude fused design system
	- Python CLI + Gradio backend for benchmarking and batch evaluation
	- 4-tab comparison dashboard — Live Compare, Benchmark, Cost Analysis, Graph Explorer

	---

	## 🤖 Supported LLM Providers

	\| # \| Provider \| API Key Env \| Default Model \| Cost/1K in \| Cost/1K out \| Speed \|
	\|---\|----------\|-------------\|---------------\|-----------\|------------\|-------\|
	\| 1 \| OpenAI \| `OPENAI_API_KEY` \| gpt-4o-mini \| $0.00015 \| $0.0006 \| ⚡ Fast \|
	\| 2 \| Anthropic Claude \| `ANTHROPIC_API_KEY` \| claude-sonnet-4 \| $0.003 \| $0.015 \| 🔵 Medium \|
	\| 3 \| Google Gemini \| `GEMINI_API_KEY` \| gemini-2.0-flash \| $0.0001 \| $0.0004 \| ⚡ Fast \|
	\| 4 \| Mistral AI \| `MISTRAL_API_KEY` \| mistral-large \| $0.002 \| $0.006 \| 🔵 Medium \|
	\| 5 \| Cohere \| `COHERE_API_KEY` \| command-r-plus \| $0.0025 \| $0.01 \| 🔵 Medium \|
	\| 6 \| 🦙 Ollama (Local) \| none needed \| llama3.2 \| $0 \| $0 \| ⚡ Local \|
	\| 7 \| OpenRouter \| `OPENROUTER_API_KEY` \| llama-3.3-70b \| $0.0004 \| $0.0004 \| 🔵 Medium \|
	\| 8 \| Groq \| `GROQ_API_KEY` \| llama-3.3-70b \| $0.00059 \| $0.00079 \| ⚡⚡ Blazing \|
	\| 9 \| xAI Grok \| `XAI_API_KEY` \| grok-3-mini \| $0.0003 \| $0.0005 \| ⚡ Fast \|
	\| 10 \| Together AI \| `TOGETHER_API_KEY` \| llama-3.1-70b-turbo \| $0.00088 \| $0.00088 \| ⚡ Fast \|
	\| 11 \| HuggingFace \| `HF_TOKEN` \| llama-3.3-70b \| $0 \| $0 \| 🔵 Medium \|
	\| 12 \| DeepSeek \| `DEEPSEEK_API_KEY` \| deepseek-chat \| $0.00014 \| $0.00028 \| ⚡ Fast \|

	### How it Works

	TypeScript (Next.js): All providers use OpenAI SDK with dynamic `baseURL` — zero extra dependencies. Anthropic uses its native SDK for tool_use support.

	Python: LiteLLM provides unified routing to all 12 providers. Falls back to OpenAI SDK with `base_url` swapping.

	```bash
	# Use any provider — just set the env var
	export ANTHROPIC_API_KEY=sk-ant-... # Use Claude
	export GROQ_API_KEY=gsk_... # Use Groq (blazing fast)
	ollama pull llama3.2 # Use Ollama (free, local)
	```

	---

	## 🦙 Ollama (Local Models)

	Run the entire system 100% locally and free with Ollama:

	```bash
	# 1. Install Ollama
	curl -fsSL https://ollama.ai/install.sh \| sh

	# 2. Pull a model
	ollama pull llama3.2 # 3B params, fast
	ollama pull qwen2.5:7b # 7B, good quality
	ollama pull deepseek-r1:7b # Reasoning model
	ollama pull phi3:14b # Strong reasoning

	# 3. Start the dashboard — Ollama is auto-detected
	cd web && npm run dev
	# Select "Ollama (Local)" in the provider dropdown
	```

	Supported Ollama Models:
	\| Model \| Size \| Quality \| Use Case \|
	\|-------\|------\|---------\|----------\|
	\| llama3.2 \| 3B \| Medium \| Fast demos, entity extraction \|
	\| llama3.2:1b \| 1B \| Low \| Ultra-fast, keyword extraction \|
	\| qwen2.5:7b \| 7B \| Medium-High \| Good all-rounder \|
	\| qwen2.5:14b \| 14B \| High \| Best local quality \|
	\| deepseek-r1:7b \| 7B \| High \| Reasoning tasks \|
	\| mistral:7b \| 7B \| Medium \| Fast general use \|
	\| gemma2:9b \| 9B \| Medium \| Google's efficient model \|
	\| phi3:14b \| 14B \| High \| Microsoft's reasoning model \|

	## 🦞 OpenClaw Integration

	This project ships with a full OpenClaw autonomous agent integration — turning the GraphRAG system into native Skills that any OpenClaw agent can discover and invoke.

	### What is OpenClaw?

	OpenClaw is the leading open-source autonomous personal AI agent runtime. It uses a frontier LLM as its backbone and runs continuously on the user's machine with full local system access. It's modular via a Skills architecture — exactly what we integrate here.

	### Architecture: CIK Model

	\| Dimension \| Our Files \| Purpose \|
	\|-----------\|-----------\|---------\|
	\| Capability \| `openclaw/skills/` \| 3 executable skills + SKILL.md docs \|
	\| Identity \| `openclaw/SOUL.md`, `IDENTITY.md` \| Agent persona, values, capabilities \|
	\| Knowledge \| `openclaw/MEMORY.md` \| Learned facts about GraphRAG performance \|

	### OpenClaw Skills

	\| Skill \| File \| What It Does \|
	\|-------\|------\|-------------\|
	\| graph_query \| `skills/graph_query/` \| Natural language → knowledge graph traversal → entities + relations + answer \|
	\| compare_pipelines \| `skills/compare_pipelines/` \| Run both pipelines side-by-side with metrics comparison \|
	\| cost_estimate \| `skills/cost_estimate/` \| Project costs across all 12 LLM providers \|

	### Using with OpenClaw Agent

	```bash
	# 1. Copy skills to your OpenClaw instance
	cp -r openclaw/skills/ ~/.openclaw/skills/
	cp openclaw/SOUL.md ~/.openclaw/
	cp openclaw/IDENTITY.md ~/.openclaw/
	cp openclaw/MEMORY.md ~/.openclaw/

	# 2. Start the GraphRAG API server
	cd web && npm run dev

	# 3. Your OpenClaw agent can now use GraphRAG:
	# "Search the knowledge graph for connections between Einstein and relativity"
	# "Compare baseline vs GraphRAG on this question"
	# "Estimate costs for 10K queries across all providers"
	```

	### Security

	We follow ClawKeeper security patterns:
	- No arbitrary code execution
	- All API keys in environment variables only
	- Graph operations are read-only by default
	- Agent boundaries defined in SOUL.md
