Question 1

What does this DeepSeek V4 Pro vs Nano Banana 2 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: DeepSeek V4 Pro or Nano Banana 2?

Accepted Answer

DeepSeek V4 Pro lists $0.435 input and $0.87 output per 1M tokens. Nano Banana 2 lists $0.50 input and $60.00 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: DeepSeek V4 Pro or Nano Banana 2?

Accepted Answer

DeepSeek V4 Pro lists 1M tokens and Nano Banana 2 lists 131.07K. DeepSeek V4 Pro therefore has the larger recorded context window, but capacity alone is not a quality score.

Question 4

Which is faster: DeepSeek V4 Pro or Nano Banana 2?

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 DeepSeek V4 Pro and Nano Banana 2 support?

Accepted Answer

DeepSeek V4 Pro records text input and text output. Nano Banana 2 records text, image, video, pdf input and text, image output. “Not documented” means the current source record is incomplete; it does not prove that a modality is unsupported.

Question 6

Should I choose DeepSeek V4 Pro or Nano Banana 2?

Accepted Answer

Consider DeepSeek V4 Pro if you need larger context or larger maximum output or a lower listed input rate or a lower listed output rate. DeepSeek V4 Pro offers downloadable weights; Nano Banana 2 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.
