Question 1

What does this Gemma 4 26B A4B IT vs GPT-5.2 Chat comparison cover?

Accepted Answer

It brings together documented inputs and outputs, token limits, deployment terms and available pricing. When both models have source-linked, verified results on a shared benchmark, those results are shown with their individual sources. The comparison is a starting point for evaluating your own workload.

Question 2

Which is cheaper: Gemma 4 26B A4B IT or GPT-5.2 Chat?

Accepted Answer

Gemma 4 26B A4B IT lists $0.07 input and $0.34 output per 1M tokens. GPT-5.2 Chat lists $1.75 input and $14.00 output. The cheaper workload depends on the mix of input and output. Long-context tiers, caching, batch processing and retries can change the bill.
