📰 Dev.to · Printo Tom

Learn why basic AI tutorials are insufficient for building real-world LLM systems and how to take your skills to the next level

intermediate Published 19 May 2026
Action Steps
  1. Build a simple LLM model using a popular framework like TensorFlow or PyTorch to understand the basics
  2. Run experiments to test the model's limitations and identify areas for improvement
  3. Configure a more complex LLM system using techniques like fine-tuning or transfer learning
  4. Test the system with real-world data to evaluate its performance
  5. Apply the lessons learned to design and build a more robust LLM system
