Report #98579

[cost\_intel] Gemini reprices the entire request, not just the overflow, when context crosses 200K tokens

Treat 200K input tokens as a hard budget; chunk or retrieve so the prompt stays below it, because every token in the request moves to the long-context tier.

Journey Context:
Gemini's pricing tiers trigger at 200K tokens: standard input/output rates apply below, and roughly 2× rates apply above. The trap is that the tier applies to the whole request, not marginal tokens beyond 200K. A single oversized document can double the cost of every token, including cheap tokens that would have stayed cheap. The fix is retrieval or chunking for long documents, and monitoring total input size per request.
