01The problem

How can an LLM produce more useful answers when it is grounded in relevant external knowledge instead of relying only on its model knowledge?

02Context

This is my exploration space for understanding retrieval-augmented generation, embeddings, vector search and grounded LLM workflows.

The goal is to understand the engineering layer around LLM applications.

The engineering layer

03Ideation

Instead of treating an LLM as a standalone answer generator, I explored a retrieval-first architecture.

The system should retrieve relevant information first and then provide that information to the model as context.

After

04Solution

The experiments focus on:

  • Document ingestion
  • Embedding generation
  • Semantic retrieval
  • Vector search
  • Context construction
  • LLM generation
  • Grounded responses

06Prototype evolution

  1. 01

    Idea

    Explore whether external context improves LLM responses.

  2. 02

    Prototype

    Create embeddings and perform semantic retrieval.

  3. 03

    Retrieval

    Retrieve the most relevant information based on similarity.

  4. 04

    Generation

    Pass retrieved context to the LLM.

  5. 05

    Evaluation

    Compare grounded responses against responses without retrieved context.

07Key learning

The quality of an LLM workflow is not only about the model. It is also about the quality of the context that reaches the model.
