Best for

Long, multi-step work like analyzing a financial report, building a deck from scattered sources, or reading documents that mix text, tables, charts, and images.

When to use it

A task has to hold context across many steps or produce a long output in one pass, and a faster Flash model keeps losing the thread.

Analysts, strategists, and ops leads on paid Gemini plans, plus teams building agents on the Gemini API.
