ragit 0.10.1

Automatic RAG Pattern Optimization Engine

ragit

RAG toolkit for Python. Document loading, chunking, vector search, LLM integration.

Installation

pip install ragit

Quick Start

You must provide an embedding source: custom function, Ollama, or any provider.

Custom Embedding Function

from ragit import RAGAssistant

def my_embed(text: str) -> list[float]:
    # Use any embedding API: OpenAI, Cohere, HuggingFace, etc.
    return embedding_vector

assistant = RAGAssistant("docs/", embed_fn=my_embed)
results = assistant.retrieve("search query")

With LLM for Q&A

def my_embed(text: str) -> list[float]:
    return embedding_vector

def my_generate(prompt: str, system_prompt: str = "") -> str:
    return llm_response

assistant = RAGAssistant("docs/", embed_fn=my_embed, generate_fn=my_generate)
answer = assistant.ask("How does authentication work?")

With Ollama (nomic-embed-text)

from ragit import RAGAssistant
from ragit.providers import OllamaProvider

# Uses nomic-embed-text for embeddings (768d)
assistant = RAGAssistant("docs/", provider=OllamaProvider())
results = assistant.retrieve("search query")

Core API

assistant = RAGAssistant(
    documents,           # Path, list of Documents, or list of Chunks
    embed_fn=...,        # Embedding function: (str) -> list[float]
    generate_fn=...,     # LLM function: (prompt, system_prompt) -> str
    provider=...,        # Or use a provider instead of functions
    chunk_size=512,
    chunk_overlap=50
)

results = assistant.retrieve(query, top_k=3)      # [(Chunk, score), ...]
context = assistant.get_context(query, top_k=3)   # Formatted string
answer = assistant.ask(question, top_k=3)         # Requires generate_fn/LLM
code = assistant.generate_code(request)           # Requires generate_fn/LLM

Document Loading

from ragit import load_text, load_directory, chunk_text

doc = load_text("file.md")
docs = load_directory("docs/", "*.md")
chunks = chunk_text(text, chunk_size=512, chunk_overlap=50, doc_id="id")

Hyperparameter Optimization

from ragit import RagitExperiment, Document, BenchmarkQuestion

def my_embed(text: str) -> list[float]:
    return embedding_vector

def my_generate(prompt: str, system_prompt: str = "") -> str:
    return llm_response

docs = [Document(id="1", content="...")]
benchmark = [BenchmarkQuestion(question="...", ground_truth="...")]

experiment = RagitExperiment(
    docs, benchmark,
    embed_fn=my_embed,
    generate_fn=my_generate
)
results = experiment.run(max_configs=20)
print(results[0])  # Best config
