Your AI has no memory. Your Rails codebase does.

📰 Dev.to · Marcin Ostrowski

Learn how AI models lack memory and how it affects their performance, and explore a Rails codebase as a contrasting example with persistent memory

intermediate Published 11 Feb 2026
Action Steps
  1. Recognize the limitations of AI models with no memory
  2. Compare the memory management of AI models to a Rails codebase
  3. Identify the implications of persistent memory in a Rails application
  4. Apply the understanding of memory management to improve AI model performance
  5. Explore techniques to mimic memory in AI models, such as using external databases or caching mechanisms
Who Needs to Know This

Developers and data scientists working with AI models and Rails applications can benefit from understanding the differences in memory management between these two systems

Key Insight

💡 AI models lack memory, which can limit their performance, whereas a Rails codebase has persistent memory, allowing for more efficient data management
