The big idea
Long context lets you put whole codebases or books in one prompt — but accuracy drops at the extremes.
Some examples
- Use for whole-codebase questions or long PDFs.
- Don't dump junk in — quality > quantity.
- Test recall with a fact you know is on page 800.
Try it!
Drop a 200-page PDF in Gemini. Ask for facts from page 1, page 100, page 199.
