04 — Questions

Which should you choose?

Which is better: DeepSeek V3 0324, DeepSeek V3.2 or GPT-5.4 nano?

GPT-5.4 nano is the better all-round choice, scoring 68/100 against DeepSeek V3.2 (64) and DeepSeek V3 0324 (54). It leads on inputs & features and context window. DeepSeek V3.2 wins on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, DeepSeek V3 0324, DeepSeek V3.2 or GPT-5.4 nano?

DeepSeek V3.2 is cheaper at $0.296 input / $0.48 output per million tokens (median across 15 API providers). DeepSeek V3 0324 costs $0.24 input / $0.90 output per million tokens (median across 5 API providers); GPT-5.4 nano costs $0.20 input / $1.25 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $0.342 per million tokens for DeepSeek V3.2 versus $0.405 for DeepSeek V3 0324 (1.2× as much) and $0.463 for GPT-5.4 nano (1.4× as much).

Which scores higher on benchmarks?

DeepSeek V3.2 scores higher on the Capabilities Index (ECI): DeepSeek V3.2 146.3 (#69 of 148), GPT-5.4 nano 145.8 (#75 of 148) and DeepSeek V3 0324 135.9 (#114 of 148). The confidence ranges of the top two overlap (144.4–147.5 vs 143.2–147.7), so treat the gap as small. On individual benchmarks: GPQA Diamond — DeepSeek V3.2 83.4%, GPT-5.4 nano 78.5%, DeepSeek V3 0324 67.6%; OTIS Mock AIME 2024–2025 — DeepSeek V3.2 87.8%, GPT-5.4 nano 87.8%, DeepSeek V3 0324 37.8%.

Which is better for coding?

There are no published SWE-bench Verified results for DeepSeek V3 0324, DeepSeek V3.2 and GPT-5.4 nano yet, so there is no like-for-like coding score. On overall capability, DeepSeek V3.2 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-5.4 nano has the largest context window at 400,000 tokens, against 163,840 for DeepSeek V3 0324 and 128,000 for DeepSeek V3.2. Maximum output per response: DeepSeek V3 0324 up to 163,840, DeepSeek V3.2 up to 64,000, GPT-5.4 nano up to 128,000 tokens.

Which can read images, PDFs, audio or video?

DeepSeek V3 0324 accepts text; DeepSeek V3.2 accepts text; GPT-5.4 nano accepts text and images. GPT-5.4 nano handles the widest range of inputs.

Are any of these open source?

DeepSeek V3 0324 and DeepSeek V3.2 publishes its weights (MIT License) and can be self-hosted; GPT-5.4 nano is proprietary.

Which is newer?

GPT-5.4 nano is the newest, released Mar 17, 2026. DeepSeek V3.2 came out Dec 1, 2025; DeepSeek V3 0324 came out Mar 24, 2025. Knowledge cutoff: DeepSeek V3.2 Jul 2024, GPT-5.4 nano Aug 31, 2025.

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.
