Gemini system instructions
Gemini takes very large inputs, including video and long PDF sets, which changes how you prompt: instead of chunking, you can hand over the whole document and ask for a targeted extraction. System instructions are set separately from the conversation and persist, so put role and format there rather than repeating them.

Explains at your level rather than the manual's, by asking one question first and building from what you already said you know.
