BasicRAG

Simple single-call RAG: retrieve once, build prompt, generate once.

Overview

Field Value
Type Generation
Algorithm Retrieve + Generate
Modality Text

How It Works

  1. Retrieve top-k documents using configured retrieval pipeline
  2. Build context from retrieved documents
  3. Generate answer using LLM with prompt template

Configuration

_target_: autorag_research.pipelines.generation.basic_rag.BasicRAGPipelineConfig
name: basic_rag
retrieval_pipeline_name: bm25
llm: gpt-4o-mini
prompt_template: |
  Context:
  {context}

  Question: {query}

  Answer:
top_k: 5
batch_size: 100

Options

Option Type Default Description
name str required Unique pipeline instance name
retrieval_pipeline_name str required Name of retrieval pipeline to use
llm str or BaseLLM required LLM instance or config name
prompt_template str default Template with {context} and {query}
top_k int 10 Documents to retrieve
batch_size int 100 Queries per batch

Prompt Template Variables

Variable Description
{context} Retrieved document contents
{query} Original query

When to Use

Good for:

  • Simple Q&A tasks
  • Baseline RAG implementation
  • Quick prototyping

Consider advanced pipelines for:

  • Multi-hop reasoning
  • Iterative retrieval
  • Complex answer synthesis
