04 — Questions

Which should you choose?

Which is better: o3-mini, Qwen3 14B or DeepSeek-R1?

It is close. Our weighted score puts them within 2 points (Qwen3 14B 54/100, o3-mini 52/100, DeepSeek-R1 51/100), so choose by what matters most for your work: o3-mini for raw capability and Qwen3 14B on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, o3-mini, Qwen3 14B or DeepSeek-R1?

Qwen3 14B is cheaper at $0.35 input / $1.40 output per million tokens (official Alibaba API price). DeepSeek-R1 costs $0.70 input / $2.60 output per million tokens (median across 11 API providers); o3-mini costs $1.10 input / $4.40 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $0.613 per million tokens for Qwen3 14B versus $1.18 for DeepSeek-R1 (1.9× as much) and $1.93 for o3-mini (3.1× as much).

Which scores higher on benchmarks?

o3-mini scores higher on the Capabilities Index (ECI): o3-mini 140.3 (#98 of 148), DeepSeek-R1 139.0 (#104 of 148) and Qwen3 14B 138.2 (#107 of 148). The confidence ranges of the top two overlap (137.4–141.9 vs 136.2–140.4), so treat the gap as small. On individual benchmarks: GPQA Diamond — o3-mini 77.0%, DeepSeek-R1 71.7%, Qwen3 14B 63.8%; OTIS Mock AIME 2024–2025 — o3-mini 76.9%, Qwen3 14B 66.4%, DeepSeek-R1 53.3%.

Which is better for coding?

There are no published SWE-bench Verified results for o3-mini, Qwen3 14B and DeepSeek-R1 yet, so there is no like-for-like coding score. On overall capability, o3-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?

o3-mini has the largest context window at 200,000 tokens, against 131,072 for Qwen3 14B and 128,000 for DeepSeek-R1. Maximum output per response: o3-mini up to 100,000, Qwen3 14B up to 8,192, DeepSeek-R1 up to 32,768 tokens.

Which can read images, PDFs, audio or video?

o3-mini accepts text; Qwen3 14B accepts text; DeepSeek-R1 accepts text. They handle the same number of input types.

Are any of these open source?

Qwen3 14B and DeepSeek-R1 publishes its weights and can be self-hosted; o3-mini is proprietary.

Which is newer?

Qwen3 14B is the newest, released Apr 29, 2025. o3-mini came out Jan 31, 2025; DeepSeek-R1 came out Jan 20, 2025. Knowledge cutoff: o3-mini May 2024, Qwen3 14B Apr 2025, 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.
