GPT-Bayes Webapp

A cloud-based Marketing Mix Modeling (MMM) solution deployed on Google Cloud Platform.

Quick Deployment

./deploy.sh production # Deploy the latest version to production
./deploy.sh development # Deploy the latest version to development

System Architecture

GPT-Bayes consists of two main components:

1. MMM Agent Alpha - A specialized GPT model with API integration

   • Interface: MMM Agent Alpha
   • Authentication: [email protected]
   • Function: Provides user interface for MMM analysis

2. Backend Service

   • Production URL: https://nextgen-mmm.pymc-labs.com
   • Development URL: https://dev-nextgen-mmm.pymc-labs.com
   • Function: Handles model fitting and parameter management via API endpoints
   • Infrastructure: Hosted on Google Cloud Engine (GCE) under the gpt-bayes project

Deployment Guide

The application runs on Google Compute Engine (GCE) under the gpt-bayes project, accessible at https://nextgen-mmm.pymc-labs.com (production) and https://dev-nextgen-mmm.pymc-labs.com (development).

Build and Push Docker Image

Build and push the Docker image to Google Artifact Registry (GAR).

./build.sh production # Build and publish to production
./build.sh development # Build and publish to development

Standard Deployment

Once the Docker image is built and pushed to GAR, use deploy.sh to update the application. This script handles:

• Updating the container in Google Artifact Registry (GAR)
• Deploying to the specified environment

./deploy.sh production # Deploy the latest version to production
./deploy.sh development # Deploy the latest version to development

Server Management

Access the specified server:

gcloud compute ssh gpt-bayes --zone us-central1-a
gcloud compute ssh dev-gpt-bayes --zone us-central1-a

Container management commands:

# List containers
docker ps -a

# Monitor container logs
docker attach CONTAINER_ID

# Access container shell
docker exec -it CONTAINER_ID /bin/bash

Container Registry Management

Build and publish to Google Artifact Registry:

./build.sh production # Build and publish to production
./build.sh development # Build and publish to development

Note: This updates the container image but doesn't affect the specified deployment.

Server Instance Management

View available Container-Optimized OS images:

gcloud compute images list --project cos-cloud --no-standard-images

Update specified container:

# Clear existing containers
gcloud compute ssh gpt-bayes --zone us-central1-a --command 'docker system prune -f -a'
gcloud compute ssh dev-gpt-bayes --zone us-central1-a --command 'docker system prune -f -a'

# Deploy new container
gcloud compute instances update-container gpt-bayes \
  --zone=us-central1-a \
  --container-image=us-central1-docker.pkg.dev/bayes-gpt/gpt-bayes/gpt-bayes:latest

gcloud compute instances update-container dev-gpt-bayes \
  --zone=us-central1-a \
  --container-image=us-central1-docker.pkg.dev/bayes-gpt/dev-gpt-bayes/dev-gpt-bayes:latest

Create new server instance:

 gcloud compute instances create-with-container gpt-bayes \
  --machine-type e2-standard-4 \
  --boot-disk-size 200GB \
  --image cos-stable-117-18613-164-13 \
  --image-project cos-cloud \
  --zone us-central1-a \
  --container-image=us-central1-docker.pkg.dev/bayes-gpt/gpt-bayes/gpt-bayes:latest \
  --tags http-server,https-server,allow-tcp-5000

 gcloud compute instances create-with-container dev-gpt-bayes \
  --machine-type e2-standard-4 \
  --boot-disk-size 20GB \
  --image cos-stable-117-18613-164-13 \
  --image-project cos-cloud \
  --zone us-central1-a \
  --container-image=us-central1-docker.pkg.dev/bayes-gpt/dev-gpt-bayes/dev-gpt-bayes:latest \
  --tags http-server,https-server,allow-tcp-5000

NGINX Configuration (Advanced)

Deploy NGINX reverse proxy updates:

cd nginx
./deploy.sh production # Deploy the latest version to production
./deploy.sh development # Deploy the latest version to development

Update backend IP address:

1. Navigate to config.yaml
2. Modify the ipAddress directive with the new IP
3. Example: ipAddress: 35.208.203.115

Local Development

1. Environment Setup

Create development environment:

# Using conda
conda env create -f environment.yml

# Using mamba (faster)
mamba env create -f environment.yml

# Activate environment
conda activate base

2. Development Server

Launch the development stack:

1. Start Redis:

redis-server

2. Start Celery worker (new terminal):

celery -A app.celery worker --loglevel=info

3. Start Flask (new terminal):

python app.py --port 5001

4. Run tests:

# Test local instance
python test_mmm_async.py local

# Test production instance
python test_mmm_async.py deployed

The test suite:

• Generates sample MMM data
• Submits to specified API endpoint
• Monitors result generation
• Displays model analytics
