Features

🔨 Build Reliable & Scalable GenAI Apps

• Swap LLMs anytime – Switch between 100+ LLMs via LiteLLM or run local models.
• Type-safe LLM calls – Use Python generics to enforce strict type safety in model interactions.
• Bring your own vector store – Connect to Qdrant, PgVector, and more with built-in support.
• Developer tools included – Manage vector stores, query pipelines, and test prompts from your terminal.
• Modular installation – Install only what you need, reducing dependencies and improving performance.

📚 Fast & Flexible RAG Processing

• Ingest 20+ formats – Process PDFs, HTML, spreadsheets, presentations, and more. Process data using Docling, Unstructured or create a custom parser.
• Handle complex data – Extract tables, images, and structured content with built-in VLMs support.
• Connect to any data source – Use prebuilt connectors for S3, GCS, Azure, or implement your own.
• Scale ingestion – Process large datasets quickly with Ray-based parallel processing.

🤖 Build Multi-Agent Workflows with Ease

• Multi-agent coordination – Create teams of specialized agents with role-based collaboration using A2A protocol for interoperability.
• Real-time data integration – Leverage Model Context Protocol (MCP) for live web access, database queries, and API integrations.
• Conversation state management – Maintain context across interactions with automatic history tracking.

🚀 Deploy & Monitor with Confidence

• Real-time observability – Track performance with OpenTelemetry and CLI insights.
• Built-in testing – Validate prompts with promptfoo before deployment.
• Auto-optimization – Continuously evaluate and refine model performance.
• Chat UI – Deploy chatbot interface with API, persistance and user feedback.

Installation

Stable Release

To get started quickly, you can install the latest stable release with:

pip install ragbits

Nightly Builds

For the latest development features, you can install nightly builds that are automatically published from the main branch:

pip install ragbits --pre

Note: Nightly builds include the latest features and bug fixes but may be less stable than official releases. They follow the version format X.Y.Z.devYYYYMMDDHHMM.

Package Contents

This is a starter bundle of packages, containing:

• ragbits-core - fundamental tools for working with prompts, LLMs and vector databases.
• ragbits-agents - abstractions for building agentic systems.
• ragbits-document-search - retrieval and ingestion piplines for knowledge bases.
• ragbits-evaluate - unified evaluation framework for Ragbits components.
• ragbits-guardrails - utilities for ensuring the safety and relevance of responses.
• ragbits-chat - full-stack infrastructure for building conversational AI applications.
• ragbits-cli - ragbits shell command for interacting with Ragbits components.

Alternatively, you can use individual components of the stack by installing their respective packages.

Quickstart

Basics

To define a prompt and run LLM:

import asyncio
from pydantic import BaseModel
from ragbits.core.llms import LiteLLM
from ragbits.core.prompt import Prompt

class QuestionAnswerPromptInput(BaseModel):
    question: str

class QuestionAnswerPrompt(Prompt[QuestionAnswerPromptInput, str]):
    system_prompt = """
    You are a question answering agent. Answer the question to the best of your ability.
    """
    user_prompt = """
    Question: {{ question }}
    """

llm = LiteLLM(model_name="gpt-4.1-nano")

async def main() -> None:
    prompt = QuestionAnswerPrompt(QuestionAnswerPromptInput(question="What are high memory and low memory on linux?"))
    response = await llm.generate(prompt)
    print(response)

if __name__ == "__main__":
    asyncio.run(main())

Document Search

To build and query a simple vector store index:

import asyncio
from ragbits.core.embeddings import LiteLLMEmbedder
from ragbits.core.vector_stores import InMemoryVectorStore
from ragbits.document_search import DocumentSearch

embedder = LiteLLMEmbedder(model_name="text-embedding-3-small")
vector_store = InMemoryVectorStore(embedder=embedder)
document_search = DocumentSearch(vector_store=vector_store)

async def run() -> None:
    await document_search.ingest("web://https://arxiv.org/pdf/1706.03762")
    result = await document_search.search("What are the key findings presented in this paper?")
    print(result)

if __name__ == "__main__":
    asyncio.run(run())

Retrieval-Augmented Generation

To build a simple RAG pipeline:

import asyncio
from collections.abc import Iterable
from pydantic import BaseModel
from ragbits.core.embeddings import LiteLLMEmbedder
from ragbits.core.llms import LiteLLM
from ragbits.core.prompt import Prompt
from ragbits.core.vector_stores import InMemoryVectorStore
from ragbits.document_search import DocumentSearch
from ragbits.document_search.documents.element import Element

class QuestionAnswerPromptInput(BaseModel):
    question: str
    context: Iterable[Element]

class QuestionAnswerPrompt(Prompt[QuestionAnswerPromptInput, str]):
    system_prompt = """
    You are a question answering agent. Answer the question that will be provided using context.
    If in the given context there is not enough information refuse to answer.
    """
    user_prompt = """
    Question: {{ question }}
    Context: {% for chunk in context %}{{ chunk.text_representation }}{%- endfor %}
    """

llm = LiteLLM(model_name="gpt-4.1-nano")
embedder = LiteLLMEmbedder(model_name="text-embedding-3-small")
vector_store = InMemoryVectorStore(embedder=embedder)
document_search = DocumentSearch(vector_store=vector_store)

async def run() -> None:
    question = "What are the key findings presented in this paper?"

    await document_search.ingest("web://https://arxiv.org/pdf/1706.03762")
    chunks = await document_search.search(question)

    prompt = QuestionAnswerPrompt(QuestionAnswerPromptInput(question=question, context=chunks))
    response = await llm.generate(prompt)
    print(response)

if __name__ == "__main__":
    asyncio.run(run())

Agentic RAG

To build an agentic RAG pipeline:

import asyncio
from ragbits.agents import Agent
from ragbits.core.embeddings import LiteLLMEmbedder
from ragbits.core.llms import LiteLLM
from ragbits.core.vector_stores import InMemoryVectorStore
from ragbits.document_search import DocumentSearch

embedder = LiteLLMEmbedder(model_name="text-embedding-3-small")
vector_store = InMemoryVectorStore(embedder=embedder)
document_search = DocumentSearch(vector_store=vector_store)

llm = LiteLLM(model_name="gpt-4.1-nano")
agent = Agent(llm=llm, tools=[document_search.search])

async def main() -> None:
    await document_search.ingest("web://https://arxiv.org/pdf/1706.03762")
    response = await agent.run("What are the key findings presented in this paper?")
    print(response.content)

if __name__ == "__main__":
    asyncio.run(main())

llm = LiteLLM(model_name="gpt-4.1-nano")
agent = Agent(llm=llm, tools=[document_search.search])

class MyChat(ChatInterface):
    async def setup(self) -> None:
        await document_search.ingest("web://https://arxiv.org/pdf/1706.03762")

    async def chat(
        self,
        message: str,
        history: ChatFormat,
        context: ChatContext,
    ) -> AsyncGenerator[ChatResponse]:
        async for result in agent.run_streaming(message):
            match result:
                case str():
                    yield self.create_live_update(
                        update_id="1",
                        type=LiveUpdateType.START,

                    )
                    yield self.create_text_response(result)
                case ToolCall():
                    yield self.create_live_update(
                        update_id="2",
                        type=LiveUpdateType.START,
                        label="Searching...",
                    )
                case ToolCallResult():
                    yield self.create_live_update(
                        update_id="2",
                        type=LiveUpdateType.FINISH,
                        label="Search",
                        description=f"Found {len(result.result)} relevant chunks.",
                    )

        yield self.create_live_update(
            update_id="1",
            type=LiveUpdateType.FINISH,
            label="Answer",
        )
