Using Long Context Well

Gemini models are known for large context windows, which is genuinely useful: you can hand the model a lot of code or documentation at once. But a big window is a tool, not a strategy. Filling it with junk still hurts.

When a big window helps

• Reasoning across many files that genuinely relate to the task.
• Summarizing or auditing a large document in one pass.
• Keeping a long reference handy instead of re-fetching it.

When it hurts

If you stuff in everything just because you can, the signal you actually need gets diluted by noise. The lesson from the Foundations track still applies: curate. A large window lets you include more relevant context, not an excuse to include irrelevant context.
