04 — Questions

Which should you choose?

Which is better: GPT-4.1 mini or DeepSeek-R1?

GPT-4.1 mini is the better all-round choice, scoring 60/100 against DeepSeek-R1 (51). It leads on price, inputs & features and context window. DeepSeek-R1 wins on capability. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, GPT-4.1 mini or DeepSeek-R1?

GPT-4.1 mini is cheaper at $0.40 input / $1.60 output per million tokens (official OpenAI API price). DeepSeek-R1 costs $0.70 input / $2.60 output per million tokens (median across 11 API providers). At a typical mix of three input tokens to one output token, that is $0.70 per million tokens for GPT-4.1 mini versus $1.18 for DeepSeek-R1 (1.7× as much).

Which scores higher on benchmarks?

DeepSeek-R1 scores higher on the Capabilities Index (ECI): DeepSeek-R1 139.0 (#104 of 148) and GPT-4.1 mini 135.0 (#115 of 148). The confidence ranges of the top two overlap (136.2–140.4 vs 131.2–136.6), so treat the gap as small. On individual benchmarks: GPQA Diamond — DeepSeek-R1 71.7%, GPT-4.1 mini 65.9%; OTIS Mock AIME 2024–2025 — DeepSeek-R1 53.3%, GPT-4.1 mini 44.7%.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-4.1 mini and DeepSeek-R1 yet, so there is no like-for-like coding score. On overall capability, DeepSeek-R1 leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.

Which has the bigger context window?

GPT-4.1 mini has the largest context window at 1,047,576 tokens, against 128,000 for DeepSeek-R1. Maximum output per response: GPT-4.1 mini up to 32,768, DeepSeek-R1 up to 32,768 tokens.

Which can read images, PDFs, audio or video?

GPT-4.1 mini accepts text, images and PDFs; DeepSeek-R1 accepts text. GPT-4.1 mini handles the widest range of inputs.

Are any of these open source?

DeepSeek-R1 publishes its weights and can be self-hosted; GPT-4.1 mini is proprietary.

Which is newer?

GPT-4.1 mini is the newest, released Apr 14, 2025. DeepSeek-R1 came out Jan 20, 2025. Knowledge cutoff: GPT-4.1 mini Apr 2024, DeepSeek-R1 Jul 2024.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
