Gemini’s 2M context window is kind of a gimmick and not useable in practice.

Not true anymore since Gemini 2.5 pro

I have quizzed it with three books (total more than 1500 pages) and it gave great answers.

Initially yes when they released 2 million context with Gemini 1.5 it wasn’t effective.

Try it with Gemini 3 pro/flash now.
