DeepSeek R1 vs Phi-4 Reasoning

This comparison does not currently contain a protocol-matched coding benchmark for both DeepSeek R1 and Phi-4 Reasoning, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Only DeepSeek R1 has a directly sourced input price: $0.70 per million tokens. Only DeepSeek R1 has a directly sourced output price: $2.50 per million tokens.

DeepSeek R1 has the larger sourced context window. DeepSeek R1 supports 163,840 tokens and Phi-4 Reasoning supports 32,768 tokens.

There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.

Both models have the same sourced self-hosting status: supported. DeepSeek R1 is open weight; Phi-4 Reasoning is open weight.

DeepSeek R1 is not documented with image input; Phi-4 Reasoning is not documented with image input. This reflects supported input modalities, not vision quality.

DeepSeek R1 has a sourced maximum output of 32,768 tokens; Phi-4 Reasoning's maximum output is not reported. A larger limit cannot be determined.

DeepSeek R1: reasoning. Phi-4 Reasoning: reasoning. Feature support does not establish relative quality.

DeepSeek R1 has 2 sourced provider routes; Phi-4 Reasoning has 0, so DeepSeek R1 has broader tracked availability.

There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
