I bought the 2000 Standard credit pack for work, but after a few background fills, I’m down to 1310. It’s taking almost 40 credits per photo, which is wrong. Please fix this error so it doesn't happen again and refund my missing credits.

Thanks @NinoFotos for sharing the details,

Here’s a breakdown to your credit usage according to each model you used for your generation:

• Gemini 3.1 (w/ Nano Banana 2): Costs 40 credits per generation > (18) * 40 = 720 credits used
• Gemini 3 (w/ Nano Banana Pro): Costs 40 credits per generation >  (2) * 40 = 80 credits used
• Firefly Image 5 (Preview): Costs 10 credits per generation > (6) * 10 = 60 credits used

In total, 26 generations cost you 720 + 80 + 60 = 860 credits, leaving your balance at 2000 – 860 = 1140 credits.

You can check the cost of each generation before proceeding here:

I hope this clears up the confusion. Let us know if you have any other questions!
