GCP Provisioned Throughput pricing

As of writing, 1 GSU is $2700/month. GSUs represent something close to compute, which makes them hard to comprehend, so let's convert them to other units. (Note: You can't buy fractional GSUs and you can get duration discounts)

You could use a common unit, like TPS, to compare them:

• 100 input TPS on Gemini 2.5 Pro is $500/mo
• 100 input TPS on Gemini 2.0 Flash is $80/mo
• 100 input TPS on Gemini 2.0 Flash Lite is $40/mo
• 100 output TPS on Gemini 2.5 Pro is $4030/mo
• 100 output TPS on Gemini 2.0 Flash is $320/mo
• 100 output TPS on Gemini 2.0 Flash Lite is $160/mo

You could also use $/mtok as the unit and compare to the non-provisioned price:

• For 2.5 Pro, this is 1.55x the normal price
• For 2.0 Flash, this is 2.06x the normal price and 4.13x the batch price
• For 2.0 Flash Lite, this is 2.06x the normal price and 4.13x the batch price
