As per the Gemini pricing page, I should receive “5,000 prompts per month (free, shared across Gemini 3), then $14 / 1,000 search queries” on a Tier 1 billing account - but it appears I am being billed immediately for grounding usage.
If the actual spend breakdown in AI Studio was clearer then I could be more certain, but I have been using Gemini 3.1 Flash Lite with <2M input tokens and been charged >$8 for this usage - so I assume it must be related to my ~900 search grounding uses in the requests.
What’s happening here? Is the pricing page incorrect and we do not have free allowance of Search Grounding?
