Steps to building AI systems with LLMโ€™s.

Iโ€™ve given a simple detailed explanation below.

Step 1 โ€“ LLMs (Large Language Models) โ€ข These are the brains of the system. โ€ข Examples: GPT (OpenAI), Gemini, Claude etc. โ€ข They generate answers, understand queries, and perform reasoning.

Step 2 โ€“ Frameworks โ€ข Frameworks help you connect the LLM with data, tools, and apps. โ€ข Examples: LangChain, Llama Index, Haystack, Txtai. โ€ข They act like a toolkit so you donโ€™t have to build everything from scratch.

Step 3 โ€“ Vector Databases โ€ข LLMs canโ€™t remember everything. They need a memory system. โ€ข Vector databases store โ€œembeddingsโ€ (numerical representations of text). โ€ข Examples: Pinecone, Weaviate, Chroma, Milvus, Qdrant. โ€ข They make searching fast and relevant (like Google search but for your private data).

Step 4 โ€“ Data Extraction โ€ข Your AI needs real-world data inputs. โ€ข Tools like Crawl4AI, FireCrawl, ScrapeGraphAI, Docling, LlamaParse help:

  • Scrape websites
  • Extract PDFs, docs, or tables
  • Clean and structure messy data

Step 5 โ€“ Open LLMs Access โ€ข Instead of calling proprietary APIs, you can run LLMs locally or via open-source providers. โ€ข Examples: Hugging Face, Ollama etc.

Step 6 โ€“ Text Embeddings โ€ข To store text in databases, you must first convert it into numbers (vectors). โ€ข Tools like OpenAI Embeddings, SBERT, Voyage AI etc handle this. โ€ข Embeddings allow semantic search (finding meaning, not just keywords).

Step 7 โ€“ Evaluation โ€ข Once built, you must test and improve your system. โ€ข Tools: Giskard, Ragas, Trulens. โ€ข They measure:

  • Accuracy
  • Hallucinations (wrong answers)
  • Relevance of results

Final Flow in Simple Words:

  1. Choose a model (LLM).
  2. Connect it with a framework.
  3. Collect data and extract it properly.
  4. Turn data into embeddings and store them in a vector DB.
  5. Give the LLM access to search that DB.
  6. Use open access tools if you want local/cheap models.
  7. Continuously evaluate and refine.

You can apply this framework in your company to design and deploy powerful AI solutions for your business.
