The big idea
Every model you use was trained on text and images scraped from the web. Some artists and writers consented; most did not. The lawsuits in 2025 are still being decided, and your generation will live with whatever rules win.
Some examples
- Ask Claude what Common Crawl is and how much of the web it covers.
- Ask ChatGPT which 2025 lawsuits actually won against AI companies.
- Ask Gemini what 'opt out' means for an artist in 2026 and whether it actually works.
- Ask Perplexity for examples of AI outputs that are nearly identical to training data.
Try it!
Ask Claude 'what artists are in your training data?' Notice the answer. Decide what that means for how you use AI art.

Practice this safely
Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.
- 1Ask AI to explain training data in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "AI and Training Data: Where It Came From and Why It Matters" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check copyright against a trusted source, teacher, adult, expert, or original document before you use it.
