honegumi-rag-assistant 0.1.5

Agentic AI system for generating Bayesian optimization code from natural language using LangGraph and OpenAI GPT models

Honegumi RAG Assistant

An agentic workflow for Bayesian optimization code generation, built with LangGraph and powered by OpenAI models. Honegumi RAG Assistant codifies the end-to-end pipeline—parameter extraction, skeleton code generation, documentation retrieval, and code synthesis—into reusable nodes orchestrated as a LangGraph. LangSmith integration tracks and visualizes your graph executions. The result? Complete, ready-to-run Bayesian optimization code generated in seconds from natural language descriptions.

• Fast iteration: eliminate manual coding and focus on science
• Built on Honegumi: Leverages deterministic skeleton generation from Honegumi
• Intelligent RAG: Retrieves relevant Ax Platform documentation to enhance code generation
• LangSmith-backed for graph tracking, versioning, and observability
• Production-ready: versionable, testable, pip-installable

🛠️ Prerequisites

• Conda (Miniconda or Anaconda)
• Python 3.11+
• OpenAI API key
• LangSmith API key (optional)

📘 Google Colab Tutorial

To help you get started quickly, we've prepared an interactive Google Colab tutorial:

Google Colab Tutorial: Getting Started with Honegumi RAG Assistant

In this tutorial, you'll learn how to:

• Install Honegumi RAG Assistant and all necessary dependencies on Colab
• Set up API keys using Colab Secrets
• Build a vector store from Ax Platform documentation
• Describe your optimization problem and generate code
• View the generated code in your Google Drive

The tutorial runs entirely in Colab—no local setup required. All you need is access to your Google Drive and valid OpenAI/LangSmith API keys.

Installation via pip

1. Create & activate a conda environment

   conda create -n honegumi_rag python=3.11 -y
   conda activate honegumi_rag
   

2. Install via pip

   pip install honegumi-rag-assistant
   

3. Configure your API keys

   Honegumi RAG Assistant will automatically look for a file named .env in your current working directory (or any parent) and load any keys it finds.

   In the folder where you'll run the CLI (or in any ancestor), create a file called .env containing:

   OPENAI_API_KEY=sk-...
   LANGCHAIN_API_KEY=lsv2_...
   

4. Build vector store (one-time setup)

   For best results with documentation retrieval, build the vector store:

   # Download the build script
   wget https://raw.githubusercontent.com/hasan-sayeed/honegumi_rag_assistant/main/scripts/build_vector_store.py
   
   # Run it
   python build_vector_store.py --output ./ax_docs_vectorstore
   
   # Set the path in your .env
   echo "AX_DOCS_VECTORSTORE_PATH=./ax_docs_vectorstore" >> .env
   

5. Run the assistant

   Now, start the honegumi-rag pipeline:

   honegumi-rag
   

   Honegumi RAG Assistant will:

   • Prompt you to describe your Bayesian optimization problem
   • Extract parameters (objectives, constraints, search space, etc.)
   • Generate a deterministic code skeleton using Honegumi
   • Retrieve relevant Ax Platform documentation
   • Generate complete, runnable Python code
   • Stream the code generation in real-time
   • Optionally save the generated code to a file

Example Problems

Chemical Process Optimization

Optimize temperature (100-300°C), pressure (1-5 bar), and catalyst concentration (0.1-1.0 M) 
to maximize conversion rate in a catalytic reaction.

Materials Design

Optimize composition of a polymer blend: Component A (0-100%), Component B (0-100%), 
and curing temperature (80-150°C) to maximize tensile strength while minimizing cost.

Machine Learning Hyperparameters

Optimize neural network hyperparameters: learning rate (1e-5 to 1e-1), 
batch size (16 to 256), and dropout rate (0.1 to 0.5) to maximize validation accuracy.
