Question 1

What does this DeepSeek-R1 vs DeepSeek Reasoner 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-R1 or DeepSeek Reasoner?

Accepted Answer

DeepSeek-R1 lists $0.70 input and $2.50 output per 1M tokens. DeepSeek Reasoner lists $0.14 input and $0.28 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-R1 or DeepSeek Reasoner?

Accepted Answer

DeepSeek-R1 lists 128K tokens and DeepSeek Reasoner lists 1M. DeepSeek Reasoner therefore has the larger recorded context window, but capacity alone is not a quality score.

Question 4

Which is faster: DeepSeek-R1 or DeepSeek Reasoner?

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-R1 and DeepSeek Reasoner support?

Accepted Answer

DeepSeek-R1 records text input and text output. DeepSeek Reasoner records text 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 DeepSeek-R1 or DeepSeek Reasoner?

Accepted Answer

Consider DeepSeek Reasoner if you need larger context or larger maximum output or a lower listed input rate or a lower listed output rate. 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.
