Question 1

What does this Gemma 4 E4B IT vs o3 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 E4B IT or o3?

Accepted Answer

Gemma 4 E4B IT lists $0.04 input and $0.20 output per 1M tokens. o3 lists $2.00 input and $8.00 output. The cheaper workload depends on the mix of input and output. Long-context tiers, caching, batch processing and retries can change the bill.

Question 3

Which has the larger context window: Gemma 4 E4B IT or o3?

Accepted Answer

Gemma 4 E4B IT lists 131.07K tokens and o3 lists 200K. o3 therefore has the larger recorded context window, but capacity alone is not a quality score.

Question 4

Which is faster: Gemma 4 E4B IT or o3?

Accepted Answer

There is no matched speed measurement for both models with the same source, host, region and date. Test the same prompts at your expected concurrency and measure time to the first useful response as well as complete task time.

Question 5

What input and output types do Gemma 4 E4B IT and o3 support?

Accepted Answer

Gemma 4 E4B IT records text, image, audio input and text output. o3 records text, image, pdf input and text output. “Not documented” means the current source record is incomplete; it does not prove that a modality is unsupported.

Question 6

Should I choose Gemma 4 E4B IT or o3?

Accepted Answer

Consider Gemma 4 E4B IT if you need a lower listed input rate or a lower listed output rate. Consider o3 if you need larger context or larger maximum output. Gemma 4 E4B IT offers downloadable weights; o3 is listed as a proprietary model. Compare licence terms and operating costs before choosing a deployment. Test both on the same representative examples and judge the output against your acceptance criteria. Include tool failures, retries and the time to a completed task.
