Why RAG
is necessary
How RAG works
Basic RAG pipeline
5 line starter
from llama_index.core import VectorStoreIndex, SimpleDirectoryReader
documents = SimpleDirectoryReader("data").load_data()
index = VectorStoreIndex.from_documents(documents)
query_engine = index.as_query_engine()
response = query_engine.query("What did the author do growing up?")
print(response)Limitations of RAG
- Summarization
- Comparison
- Multi-part questions
Naive RAG failure points:
RAG is necessary
but not sufficient
Two ways
to improve RAG:
- Improve your data
- Improve your querying
What is an agent anyway?
- Semi-autonomous software
- Accepts a goal
- Uses tools to achieve that goal
- Exact steps to resolution not specified
RAG pipeline
⚠️ Single-shot
⚠️ No query understanding/planning
⚠️ No tool use
⚠️ No reflection, error correction
⚠️ No memory (stateless)
Agentic RAG
✅ Multi-turn
✅ Query / task planning layer
✅ Tool interface for external environment
✅ Reflection
✅ Memory for personalization
From simple to advanced agents
Routing
Conversation memory
Query planning
Tool use
Tools unleash the power of LLMs
Combine agentic strategies
and then go further
- Routing
- Memory
- Planning
- Tool use
Agentic strategies
- Multi-turn
- Reasoning
- Reflection
Full agent
3 agent
reasoning loops
- Sequential
- DAG-based
- Tree-based
Sequential reasoning
DAG-based reasoning
Self reflection
Tree-based reasoning
Exploration vs exploitation
