04 — Questions

Which should you choose?

Which is better: DeepSeek-V3, GPT-4.1 mini or Magistral Small?

GPT-4.1 mini is the better all-round choice, scoring 60/100 against Magistral Small (50) and DeepSeek-V3 (50). It leads on capability, inputs & features and context window. DeepSeek-V3 wins on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, DeepSeek-V3, GPT-4.1 mini or Magistral Small?

DeepSeek-V3 is cheaper at $0.32 input / $1.10 output per million tokens (median across 5 API providers). GPT-4.1 mini costs $0.40 input / $1.60 output per million tokens (official OpenAI API price); Magistral Small costs $0.50 input / $1.50 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $0.515 per million tokens for DeepSeek-V3 versus $0.70 for GPT-4.1 mini (1.4× as much) and $0.75 for Magistral Small (1.5× as much).

Which scores higher on benchmarks?

GPT-4.1 mini scores higher on the Capabilities Index (ECI): GPT-4.1 mini 135.0 (#115 of 148), Magistral Small 133.2 (#120 of 148) and DeepSeek-V3 132.3 (#121 of 148). The confidence ranges of the top two overlap (131.2–136.6 vs 128.9–134.4), so treat the gap as small. On individual benchmarks: GPQA Diamond — GPT-4.1 mini 65.9%, DeepSeek-V3 56.5%, Magistral Small 56.1%; OTIS Mock AIME 2024–2025 — GPT-4.1 mini 44.7%, Magistral Small 30.0%, DeepSeek-V3 15.8%.

Which is better for coding?

There are no published SWE-bench Verified results for DeepSeek-V3, GPT-4.1 mini and Magistral Small yet, so there is no like-for-like coding score. On overall capability, GPT-4.1 mini leads, which tends to carry over to coding, but test on your own codebase. All three 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 131,072 for DeepSeek-V3 and 131,072 for Magistral Small. Maximum output per response: DeepSeek-V3 up to 8,192, GPT-4.1 mini up to 32,768, Magistral Small up to 8,192 tokens.

Which can read images, PDFs, audio or video?

DeepSeek-V3 accepts text; GPT-4.1 mini accepts text, images and PDFs; Magistral Small accepts text. GPT-4.1 mini handles the widest range of inputs.

Are any of these open source?

DeepSeek-V3 and Magistral Small publishes its weights (DeepSeek Model License and Apache 2.0) and can be self-hosted; GPT-4.1 mini is proprietary.

Which is newer?

Magistral Small is the newest, released Jun 10, 2025. GPT-4.1 mini came out Apr 14, 2025; DeepSeek-V3 came out Dec 26, 2024. Knowledge cutoff: GPT-4.1 mini Apr 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.
