Which Artificial Intelligence engine is best for your classroom?


What Is an AI Engine?
An AI engine (often called a large language model or LLM) is a computer system trained on massive amounts of text, images, and data so it can answer questions, write, summarize, analyze, and create content.
Think of AI engines the way historians think about institutions: who controls them, who has access, and how they shape society all matter.

Big Ideas to Remember
  • Proprietary AI = controlled by companies, polished, powerful, but limited access
  • Open-source AI = public, customizable, but requires expertise
  • AI engines are shaped by economics, government policy, and ethics, just like historical institutions.

Class Discussion Questions
  1. Should powerful AI tools be controlled by companies or made public?
  2. How might AI affect education the way industrialization affected labor?
  3. Who should be responsible when AI gives incorrect or harmful information?
​
You can frame these AI engines in your U.S. History classroom by drawing parallels:
  • Closed proprietary models as “industrial leaders” (like AI Big Tech),
  • Open-source models as “grassroots movements”,
  • The AI ecosystem as a landscape influenced by access, governance, cost, and community — much like historical economic and cultural evolution.
Use AI as a tool — not a replacement for critical thinking!
