Why price difference with the same pro model?

I was scrolling models in the playground in AI studio and I noticed that Gemini 3.1 pro preview has 2 different prices:

If you select “Gemini 3.1 Pro Preview”, it says:

<=200k tokens Input $2.00 / Output $12.00

>200k tokens Input $4.00 / Output $18.00

While if you select “Gemini Pro Latest” it says “Points to Gemini 3.1 Pro Preview”, and is priced at:

<=200k tokens Input $1.25 / Output $10.00

>200k tokens Input $2.50 / Output $15.00

This is either not the same model and therefore the description on Gemini Pro Latest is wrong, or if it’s the same model then one of the 2 has the wrong pricing, or it doesn’t make any sense.

Can anyone from Google clarify what’s going on?

Hi @BReal

Thank you for flagging this

We are working on the updating the pricing displayed in AI Studio
