RAG app stack

Every company will benefit on a large scale if any employee can leverage the vast amount of company documents quickly and easily. This is a dream that a couple of years back was impossible but today is at your fingers's tip. I have built a lot of these tools so I will give my recommended tech stack:

• App orchestration: LangChain, LLamaIndex
• LLM providers: OpenAI, Anthropic, Amazon Bedrock, Ollama for local open-source model inference.
• Embedding providers: Nomic, Cohere, Ollama for local open-source model inference.
• Vector databases: Milvus, PostgreSQL with pgvector extension, Amazon OpenSearch
• Graph databases: Neo4J, Amazon Neptune.
• Easy UI: Gradio, Streamlit.
• AI Agents: LanGraph, CrewAI

If you want some more insights on this type of application or a detailed tutorial let me know.
