04 — Questions

Which should you choose?

Which is better: GPT-5.4 mini or Qwen3.6 Plus?

It is close. Our weighted score puts them within 3 points (Qwen3.6 Plus 66/100, GPT-5.4 mini 63/100), so choose by what matters most for your work: GPT-5.4 mini for raw capability, Qwen3.6 Plus on price and Qwen3.6 Plus for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, GPT-5.4 mini or Qwen3.6 Plus?

Qwen3.6 Plus is cheaper at $0.50 input / $3.00 output per million tokens (official Alibaba API price). GPT-5.4 mini costs $0.75 input / $4.50 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $1.13 per million tokens for Qwen3.6 Plus versus $1.69 for GPT-5.4 mini (1.5× as much).

Which scores higher on benchmarks?

GPT-5.4 mini scores higher on the Capabilities Index (ECI): GPT-5.4 mini 148.8 (#56 of 148) and Qwen3.6 Plus 147.6 (#59 of 148). The confidence ranges of the top two overlap (147.1–150.5 vs 145.4–149.3), so treat the gap as small. On individual benchmarks: GPQA Diamond — Qwen3.6 Plus 88.4%, GPT-5.4 mini 86.9%; FrontierMath Tiers 1–3 — GPT-5.4 mini 51.2%, Qwen3.6 Plus 38.3%; OTIS Mock AIME 2024–2025 — Qwen3.6 Plus 93.3%, GPT-5.4 mini 88.9%; SimpleQA Verified — Qwen3.6 Plus 44.1%, GPT-5.4 mini 29.4%.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-5.4 mini yet, so there is no like-for-like coding score. On overall capability, GPT-5.4 mini 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?

Qwen3.6 Plus has the largest context window at 1,000,000 tokens, against 400,000 for GPT-5.4 mini. Maximum output per response: GPT-5.4 mini up to 128,000, Qwen3.6 Plus up to 65,536 tokens.

Which can read images, PDFs, audio or video?

GPT-5.4 mini accepts text and images; Qwen3.6 Plus accepts text, images and video. Qwen3.6 Plus handles the widest range of inputs.

Are any of these open source?

No. GPT-5.4 mini and Qwen3.6 Plus are proprietary and only available through APIs and apps.

Which is newer?

Qwen3.6 Plus is the newest, released Apr 2, 2026. GPT-5.4 mini came out Mar 17, 2026. Knowledge cutoff: GPT-5.4 mini Aug 31, 2025, Qwen3.6 Plus 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.
