rag-playbook 0.1.0

Compare RAG patterns with real benchmarks. Run one command, see which pattern wins.

rag-playbook

Stop guessing which RAG pattern to use. Compare them with real numbers.

---

Every RAG tutorial teaches you how to build patterns. None of them tell you which one to actually use.

rag-playbook runs the same query against 8 production-tested RAG patterns and shows you which one wins — with real numbers for quality, latency, and cost.

Quick Start

pip install rag-playbook[openai]
export OPENAI_API_KEY=sk-...

# Compare all patterns on your documents
rag-playbook compare --data ./my_docs/ --query "What is the refund policy?"

Patterns

#	Pattern	Best For	Latency	Cost
01	Naive	Simple factual queries	~1s	$
02	Hybrid Search	Queries with codes, IDs, exact terms	~1.1s	$
03	Re-ranking	When top-K retrieval isn't precise enough	~1.4s	$$
04	Parent-Child	Long documents with clear sections	~1s	$
05	Query Decomposition	Complex multi-part questions	~2.1s	$$$
06	HyDE	Short or ambiguous queries	~1.5s	$$
07	Self-Correcting	When hallucination risk is high	~2.8s	$$$
08	Agentic	When query intent is unclear	~3.2s	$$$$

Use as a Library

import asyncio
from rag_playbook import create_pattern, Settings
from rag_playbook.core.embedder import create_embedder
from rag_playbook.core.llm import create_llm
from rag_playbook.core.vector_store import create_vector_store

async def main():
    settings = Settings()  # Reads from .env / environment
    llm = create_llm(settings)
    embedder = create_embedder(settings)
    store = create_vector_store("memory")

    pattern = create_pattern("reranking", llm=llm, embedder=embedder, store=store)

    # Index your documents first (or use the CLI: rag-playbook ingest)
    result = await pattern.query("What is the refund policy?")

    print(result.answer)
    print(f"Cost: ${result.metadata.cost_usd:.4f}")
    print(f"Latency: {result.metadata.latency_ms:.0f}ms")

asyncio.run(main())

See examples/ for more usage patterns.

CLI Commands

Command	Description
rag-playbook compare	Compare patterns side-by-side on your documents
rag-playbook run	Run a single pattern
rag-playbook recommend	Get an LLM-powered pattern recommendation
rag-playbook ingest	Load, chunk, embed, and index documents
rag-playbook bench	Run full benchmark suite
rag-playbook patterns	List all available patterns

Run a single pattern

rag-playbook run reranking --data ./docs/ --query "What are the laptop specs?"

List available patterns

rag-playbook patterns

Get a pattern recommendation

rag-playbook recommend --query "What is the refund policy?"

Ingest documents

rag-playbook ingest --data ./sample_docs/

See CLI Reference for full usage.

Configuration

All settings can be configured via environment variables with the RAG_ prefix:

# .env
RAG_LLM_PROVIDER=openai
RAG_LLM_MODEL=gpt-4o-mini
RAG_EMBEDDING_MODEL=text-embedding-3-small
RAG_EMBEDDING_DIMENSIONS=1536
RAG_TOP_K=5
RAG_CHUNK_SIZE=512
RAG_CHUNK_OVERLAP=50

Or pass a Settings object directly in code. See .env.example for all options.

Architecture

Document → Chunk → EmbeddedChunk → RetrievedChunk → RAGResult
              │         │                │               │
          Chunker    Embedder       VectorStore        LLM

Design patterns used:

• Strategy — Swappable LLM and embedding providers
• Repository — Vector store abstraction
• Template Method — BaseRAGPattern with overridable pipeline steps
• Decorator — CachedEmbedder wrapping any embedder with SHA-256 keyed cache
• Factory — create_pattern(), create_llm(), create_embedder(), etc.

See Architecture Guide for details.
