By skyforbes I moved from Gemini 2.5 Image to
gemini-3-pro-image-preview using the paid Gemini API (Tier 1). AI Studio clearly shows usage for gemini-3-pro-image and I am hitting the daily RPD limit, using API keys from projects that are linked to my only billing account.
But in Cloud Billing and in AI Studio Billing there is zero cost for Gemini 3, and only Gemini 2.5 SKUs show up, even for days that are already 4 days old.
Is anyone else seeing Gemini 3 Pro Image Preview not appear in billing at all? Is this some hidden free preview, a billing lag, or did I misconfigure something even though the calls work and rate limits increase?
