R2R is an advanced AI retrieval system supporting Retrieval-Augmented Generation (RAG) with production-ready features. Built around a RESTful API, R2R offers multimodal content ingestion, hybrid search, knowledge graphs, and comprehensive document management.

R2R also includes a Deep Research API, a multi-step reasoning system that fetches relevant data from your knowledgebase and/or the internet to deliver richer, context-aware answers for complex queries.

# Basic search
results = client.retrieval.search(query="What is DeepSeek R1?")
# RAG with citations
response = client.retrieval.rag(query="What is DeepSeek R1?")
# Deep Research RAG Agent
response = client.retrieval.agent(
  message={"role":"user", "content": "What does deepseek r1 imply? Think about market, societal implications, and more."},
  rag_generation_config={
    "model"="anthropic/claude-3-7-sonnet-20250219",
    "extended_thinking": True,
    "thinking_budget": 4096,
    "temperature": 1,
    "top_p": None,
    "max_tokens_to_sample": 16000,
  },
