Gemini Pro user reports only ~25K usable tokens despite advertised 1M context window

A user who bought a Gemini Pro slot via a Jio family plan ($5) complains that the advertised 1M-token context window doesn't materialize in practice. Writing serialized roleplay fiction at 500-800 words per chapter, he found that by chapter 30 the model had completely forgotten chapters 1-6.
He estimates only about 20,000-25,000 tokens are actually usable and questions whether the 1M claim is marketing. The post offers no official explanation, but echoes common complaints about effective context limits and long-context recall degradation.
