What Gemini 2.5 Flash Image (Nano Banana) is suited for
A 1.0M window is large enough to hold a substantial part of a codebase in one turn, so it suits whole-repo refactors and long agent sessions where the history keeps growing. It answers directly rather than reasoning at length, which keeps latency and output cost down on routine edits. Tool and function calling are supported, so it can drive an agent loop. It accepts images, so screenshots and diagrams can go straight into the prompt. Cached input is billed at $0.03 against $0.30 fresh, which is the difference that matters most for agent work — the same context is resent on every turn.
