By finishing the "LLM Twin: Building Your Production-Ready AI Replica" free course, you will learn how to design, train, and deploy a production-ready LLM twin of yourself powered by LLMs, vector DBs, and LLMOps good practices.

Why should you care? 🫵

→ No more isolated scripts or Notebooks! Learn production ML by building and deploying an end-to-end production-grade LLM system.

You will learn how to architect and build a real-world LLM system from start to finish - from data collection to deployment.

You will also learn to leverage MLOps best practices, such as experiment trackers, model registries, prompt monitoring, and versioning.

The end goal? Build and deploy your own LLM twin.

What is an LLM Twin? It is an AI character that learns to write like somebody by incorporating its style and personality into an LLM.

• 1. The architecture of the LLM Twin is split into 4 Python microservices:
  • 1.1. The data collection pipeline
  • 1.2. The feature pipeline
  • 1.3. The training pipeline
  • 1.4. The inference pipeline
• 2. Who is this for?
• 3. How will you learn?
• 4. Costs?
• 5. Questions and troubleshooting
• 6. Lessons
  • 6.1. System design
  • 6.2. Data engineering: Gather & store the data for your LLM twin
  • 6.3. Feature pipeline: prepare data for LLM fine-tuning & RAG
  • 6.4. Training pipeline: fine-tune your LLM twin
  • 6.5. Inference pipeline: serve your LLM twin
  • 6.6. Bonus: refactor and optimize the RAG system
• 7. Install & Usage

• 11. Next steps 🧑‍💻

• Crawl your digital data from various social media platforms, such as Medium, Substack and GitHub.
• Clean, normalize and load the data to a Mongo NoSQL DB through a series of ETL pipelines.
• Send database changes to a RabbitMQ queue using the CDC pattern.
• Learn to package the crawlers as AWS Lambda functions.

• Consume messages in real-time from a queue through a Bytewax streaming pipeline.
• Every message will be cleaned, chunked, embedded and loaded into a Qdrant vector DB.
• In the bonus series, we refactor the cleaning, chunking, and embedding logic using Superlinked, a specialized vector compute engine. We will also load and index the vectors to a Redis vector DB.

• Create a custom instruction dataset based on your custom digital data to do SFT.
• Fine-tune an LLM using LoRA or QLoRA.
• Use Comet ML's experiment tracker to monitor the experiments.
• Evaluate the LLM using Opik
• Save and version the best model to the Hugging Face model registry.
• Run and automate the training pipeline using AWS SageMaker.

• Load the fine-tuned LLM from the Hugging Face model registry.
• Deploy the LLM as a scalable REST API using AWS SageMaker inference endpoints.
• Enhance the prompts using advanced RAG techniques.
• Monitor the prompts and LLM generated results using Opik
• In the bonus series, we refactor the advanced RAG layer to write more optimal queries using Superlinked.
• Wrap up everything with a Gradio UI (as seen below) where you can start playing around with the LLM Twin to generate content that follows your writing style.

Along the 4 microservices, you will learn to integrate 4 serverless tools:

• Comet ML as your experiment tracker and data registry;
• Qdrant as your vector DB;
• AWS SageMaker as your ML infrastructure;
• Opik as your prompt evaluation and monitoring tool.

Audience: MLE, DE, DS, or SWE who want to learn to engineer production-ready LLM & RAG systems using LLMOps good principles.

Level: intermediate

Prerequisites: basic knowledge of Python and ML

The course contains 10 hands-on written lessons and the open-source code you can access on GitHub, showing how to build an end-to-end LLM system.

Also, it includes 2 bonus lessons on how to improve the RAG system.

You can read everything at your own pace.

The articles and code are completely free. They will always remain free.

If you plan to run the code while reading it, you must know that we use several cloud tools that might generate additional costs.
