Practical overview

When it fits

Use the repository when learning from concrete Python examples of Bedrock applications, especially when investigating RAG and vector-database-backed Q&A.

Who it is for

  • Python developers learning to build generative AI applications with Amazon Bedrock.
  • Developers exploring retrieval-augmented Q&A with vector databases.

Documented uses

  • Explore a Q&A bot using pgvector, Aurora PostgreSQL and Amazon Bedrock.
  • Study sample application patterns for resume screening, CSV analysis and recipe generation.
  • Review examples that use LangChain or Streamlit in generative AI applications.
Before you choose

Requirements & limits

The repository is public and licensed under MIT-0.

  • RAG examples name Amazon Aurora, RDS and OpenSearch as database integrations.
  • The Unified AI Q&A sample specifically combines pgvector, Aurora PostgreSQL, Amazon Bedrock and Streamlit.
  • Setup and dependencies are described in individual project READMEs rather than one universal setup procedure.
  • The repository is a code-and-tutorial collection, not a single hosted application.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a repository sample project

Prepare one of the documented sample projects for launching its Streamlit app.

Before you start

  • Clone the public repository.
  • Choose a sample project directory with a README setup guide.
  • Use a virtual environment, environment files and dependencies as specified by that project’s README.

Steps

  1. Clone the repository.

  2. Navigate to the desired project directory.

  3. Follow its README to set up the virtual environment, environment files and dependencies.

  4. Launch the Streamlit app for the selected project.

Expected outcome

A selected sample’s Streamlit application is launched after following its project-specific setup instructions.

Guide limitations

  • Setup details differ by project and are provided in the individual README files.
  • The general setup sequence does not specify service credentials, dependency versions or commands.
