04 — Questions

Which should you choose?

Which is better: DeepSeek V3 0324, DeepSeek-V3.1 or Qwen3 8B?

It is close. Our weighted score puts them within 1 points (Qwen3 8B 56/100, DeepSeek-V3.1 55/100, DeepSeek V3 0324 54/100), so choose by what matters most for your work: DeepSeek-V3.1 for raw capability, Qwen3 8B on price and DeepSeek V3 0324 for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, DeepSeek V3 0324, DeepSeek-V3.1 or Qwen3 8B?

Qwen3 8B is cheaper at $0.18 input / $0.70 output per million tokens (official Alibaba API price). DeepSeek V3 0324 costs $0.24 input / $0.90 output per million tokens (median across 5 API providers); DeepSeek-V3.1 costs $0.385 input / $1.25 output per million tokens (median across 8 API providers). At a typical mix of three input tokens to one output token, that is $0.31 per million tokens for Qwen3 8B versus $0.405 for DeepSeek V3 0324 (1.3× as much) and $0.601 for DeepSeek-V3.1 (1.9× as much).

Which scores higher on benchmarks?

DeepSeek-V3.1 scores higher on the Capabilities Index (ECI): DeepSeek-V3.1 139.9 (#100 of 148), Qwen3 8B 136.2 (#113 of 148) and DeepSeek V3 0324 135.9 (#114 of 148). The confidence ranges of the top two overlap (136.1–143.3 vs 129.7–138.1), so treat the gap as small.

Which is better for coding?

There are no published SWE-bench Verified results for DeepSeek V3 0324, DeepSeek-V3.1 and Qwen3 8B yet, so there is no like-for-like coding score. On overall capability, DeepSeek-V3.1 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?

DeepSeek V3 0324 has the largest context window at 163,840 tokens, against 131,072 for DeepSeek-V3.1 and 131,072 for Qwen3 8B. Maximum output per response: DeepSeek V3 0324 up to 163,840, DeepSeek-V3.1 up to 8,192, Qwen3 8B up to 8,192 tokens.

Which can read images, PDFs, audio or video?

DeepSeek V3 0324 accepts text; DeepSeek-V3.1 accepts text; Qwen3 8B accepts text. They handle the same number of input types.

Are any of these open source?

Yes, all three publish their weights (MIT License), so you can self-host them.

Which is newer?

DeepSeek-V3.1 is the newest, released Aug 21, 2025. Qwen3 8B came out Apr 28, 2025; DeepSeek V3 0324 came out Mar 24, 2025. Knowledge cutoff: Qwen3 8B Apr 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.
