This technical guide walks through deploying an AI-powered Food Recipe Assistant application on Sevalla's Application Hosting platform. We'll cover the deployment process, configuration, and best practices for hosting a Python FastAPI application with AI capabilities.

Posted on Medium first:





Project Overview



The AI Food Recipe Assistant is a modern web application that leverages:




  • FastAPI for the backend API

  • OpenAI's GPT-3.5 and DALL-E 3 for AI-powered recipe and image generation

  • HTML/TailwindCSS/AlpineJS for the frontend

  • Environment variables for secure configuration

  • Docker for containerization



Application code is available on



Intelligent Recipe Generation

Our deployed AI Food Recipe Assistant will demonstrate the powerful AI capabilities like:



Natural Language Understanding: Users can request recipes in plain English (e.g., “vegan chocolate lava cake”)

Dietary Customization: Automatically adapts recipes for various preferences:




  1. Vegetarian/Vegan options

  2. Gluten-free alternatives

  3. Keto-friendly versions

  4. Other dietary restrictions

  5. Cuisine Fusion: Supports multiple cuisine types and cultural adaptations





AI-Generated Content



Each recipe request generates the following:



Detailed Recipe Information:




  • Ingredient lists with precise measurements

  • Step-by-step cooking instructions

  • Cooking times and temperatures

  • Serving suggestions

  • Nutritional information



Visual Content:




  • DALL-E 3 generated photorealistic food images

  • Appetizing presentation suggestions

  • Visual cooking guides

  • Learning Resources:

  • Cooking technique explanations

  • Ingredient substitution options

  • Tips for perfect execution





Sample Output



Here's an example of what the application generates for a "Vegan Italian Choco Lava Cake":




CODE
{
"recipe": {
"title": "Vegan Italian Choco Lava Cake",
"description": "Indulge in the decadence of a vegan Italian-style choco lava cake that will impress even the most discerning dessert lovers!",
"ingredients": [
"1 cup all-purpose flour",
"1/2 cup unsweetened cocoa powder",
"1/2 cup sugar",
"1/2 cup plant-based milk",
"// ... other ingredients"
],
"instructions": [
"1. Preheat oven to 375°F (190°C)",
"2. Mix dry ingredients in a bowl",
"// ... detailed steps"
]
},
"image_url": "https://ai-generated-image.example/vegan-lava-cake.jpg",
"learning_resources": [
{
"type": "video",
"title": "Master the Art of Vegan Lava Cakes",
"url": "https://youtube.com/cookingtutorials"
}
]
}







Let’s deploy this…







Prerequisites



Before deploying to Sevalla, ensure you have:




  1. A


  2. for containerized deployment:


    CODE
    FROM python:3.9-slim
    WORKDIR /app
    COPY requirements.txt .
    RUN pip install --no-cache-dir -r requirements.txt
    COPY . .
    EXPOSE 8000
    CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]



  3. Configure environment variables





CODE
   cp .env.example .env
# Edit .env and add your OpenAI API key:
# OPENAI_API_KEY=your_api_key_here








  1. Run the application




CODE
   uvicorn main:app --reload






Feel free to create your own application by referring these




  1. Log into Sevalla dashboard

  2. Click "Applications" > "Add application"

  3. Select "Git repository" and connect to your repository

  4. Choose deployment settings:


    • Repository: your-repo-url

    • Branch: main

    • Build Environment: Python

    • Region: Choose nearest to your users








3. Environment Variables



We will now add “OPENAI_API_KEY” inside “Environment variables” to use the power of AI in our application to suggest AI-generated recipes.






Application Architecture on Sevalla



The deployed application architecture includes(:




  • SSL/TLS encryption

  • DDoS protection through Cloudflare

  • Secure environment variable storage

  • Isolated application environment






Performance Optimizations



Sevalla automatically implements several performance features:





  1. CDN Integration: Global content delivery


  2. Edge Caching: Improved response times


  3. Auto-scaling: Dynamic resource allocation


  4. Load Balancing: Distributed traffic handling






Deployment Verification



After deployment, verify the application:




  1. Access the provided domain (e.g., https://ai-food-assistant-ll3mo.kinsta.app/)

  2. Test the recipe generation endpoint

  3. Monitor application logs for any issues

  4. Verify environment variables are properly set






Troubleshooting Tips



Common issues and solutions:





  1. Port Configuration: Ensure the application uses the PORT environment variable


  2. Build Failures: Check requirements.txt for compatibility


  3. Runtime Errors: Monitor logs for application errors


  4. Environment Variables: Verify all required variables are set






Why Sevalla for AI Application Deployment?



Building and deploying AI applications can be challenging. Whether you're a developer working on a side project or part of a team building the next big AI product, you need a reliable and easy way to get your app into production. That's where .
