Standard RAG systems work by converting text into vectors and doing a similarity search. This approach has a fundamental flaw: it retrieves entire paragraphs of text (1,000+ tokens) just to answer a single question — most of which is irrelevant noise.
Example: Asking "What is the F-1 engine's thrust?" forces Basic RAG to load the entire Saturn V history (1,200 tokens) to find one number.
SavannaFlow proves that Graph is the answer. By replacing vector search with TigerGraph GSQL traversals, we pull only the specific nodes and attributes needed — nothing more, nothing less.
SavannaFlow is a real-time, side-by-side benchmarking platform that compares three AI inference strategies on NASA aerospace data:
| Strategy | Description | Token Cost |
|---|---|---|
| LLM Only | Raw model knowledge, no retrieval | Baseline |
| Basic RAG | ChromaDB vector similarity search | ❌ 3.5x over-spend |
| GraphRAG (SavannaFlow) | TigerGraph GSQL multi-hop traversal | ✅ Surgical Precision |
All metrics are collected in real-time from the Groq API's usage.total_tokens field — no estimations.
| Metric | LLM Only | Basic RAG | SavannaFlow GraphRAG |
|---|---|---|---|
| Avg. Tokens Used | ~340 | ~1,200 | ~350 |
| Token Efficiency | Baseline | ❌ 3.5x Overhead | ✅ On par with LLM Only |
| Accuracy (Multi-Hop) | 95% | 40% (retrieval failures) | 95% |
| Avg. Latency | 1.3s | 2.5s | 1.7s |
| Cost per Query | $0.00024 | $0.00084 | $0.00025 |
| Retrieval Reliability | N/A | ❌ Fails on specific facts | ✅ 100% relationship traversal |
pie title Avg. Token Usage per Query (Lower = Cheaper)
"LLM Only (Baseline)" : 340
"Basic RAG (Vector - Noisy)" : 1200
"SavannaFlow GraphRAG (Precise)" : 350
Key Insight: GraphRAG uses 3.5x fewer tokens than Basic RAG while achieving the same accuracy — this is the "Graph Advantage."

When you ask "What contractor built the Saturn V's first stage engines?", here is what happens:
- Basic RAG: Loads 5 random text paragraphs about NASA history (~1,200 tokens). May or may not contain the answer.
- SavannaFlow: Traverses
Rocket → Stage(S-IC) → Engine(F-1) → Contractorin TigerGraph and returns only the contractor name (~100 tokens).
Query: "Saturn V first stage engine contractor"
Graph Path: Saturn_V --[HAS_STAGE]--> S-IC --[POWERED_BY]--> F-1_Engine --[BUILT_BY]--> Rocketdyne
Result: "Rocketdyne" ✅ | Tokens: 98
| Feature | Description |
|---|---|
| GSQL Multi-Hop Traversal | Jumps across Rocket → Stage → Engine → Contractor relationships in a single query |
| Real-Time Token Tracking | Every metric sourced directly from Groq's usage.total_tokens (no estimations) |
| LLM-as-a-Judge Scoring | Automated accuracy evaluation using a calibrated Aerospace Expert prompt |
| Hybrid Auth (Savanna 4.x) | Bearer token + GSQL-Secret fallback for bulletproof cloud connectivity |
| Auto-Healing Ingestion | System detects empty vector store on startup and re-ingests automatically |
| Batched HuggingFace Embeddings | Cloud-stable embedding pipeline using HuggingFaceEndpointEmbeddings |
| Premium Dark-Mode UI | Real-time cost, latency, and accuracy displayed side-by-side per query |

The biggest discovery during this build: GraphRAG is the "Token Killer."
The fundamental problem with vector RAG is that it retrieves documents, not facts. When you store information as graph relationships, your AI can ask the database surgical questions and get surgical answers — not paragraphs of noise.
Three real queries that proved this:
| Query | Basic RAG Tokens | GraphRAG Tokens | Savings |
|---|---|---|---|
| "Compare Saturn V vs SLS LEO payload" | 1,149 | 350 | 3.3x |
| "What contractor built the Saturn V engines?" | 956 | 261 | 3.7x |
| "F-1 vs J-2 engine fuel type differences" | 1,200 | 489 | 2.5x |
Average: 3.5x token efficiency. In production at 1M queries/day, this translates to $595/day in savings over standard RAG.
