04 — Questions

Which should you choose?

Which is better: GPT-5.4 nano or Qwen3 Max?

GPT-5.4 nano is the better all-round choice, scoring 68/100 against Qwen3 Max (50). It leads on capability, price, inputs & features and context window. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, GPT-5.4 nano or Qwen3 Max?

GPT-5.4 nano is cheaper at $0.20 input / $1.25 output per million tokens (official OpenAI API price). Qwen3 Max costs $1.20 input / $6.00 output per million tokens (official Alibaba API price). At a typical mix of three input tokens to one output token, that is $0.463 per million tokens for GPT-5.4 nano versus $2.40 for Qwen3 Max (5.2× as much).

Which scores higher on benchmarks?

GPT-5.4 nano scores higher on the Capabilities Index (ECI): GPT-5.4 nano 145.8 (#75 of 148) and Qwen3 Max 142.4 (#91 of 148). The confidence ranges of the top two overlap (143.2–147.7 vs 140.0–144.6), so treat the gap as small. On individual benchmarks: GPQA Diamond — GPT-5.4 nano 78.5%, Qwen3 Max 72.6%; FrontierMath Tiers 1–3 — GPT-5.4 nano 44.9%, Qwen3 Max 19.0%; OTIS Mock AIME 2024–2025 — GPT-5.4 nano 87.8%, Qwen3 Max 73.3%; SimpleQA Verified — Qwen3 Max 48.8%, GPT-5.4 nano 11.7%.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-5.4 nano and Qwen3 Max yet, so there is no like-for-like coding score. On overall capability, GPT-5.4 nano 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?

GPT-5.4 nano has the largest context window at 400,000 tokens, against 262,144 for Qwen3 Max. Maximum output per response: GPT-5.4 nano up to 128,000, Qwen3 Max up to 65,536 tokens.

Which can read images, PDFs, audio or video?

GPT-5.4 nano accepts text and images; Qwen3 Max accepts text. GPT-5.4 nano handles the widest range of inputs.

Are any of these open source?

No. GPT-5.4 nano and Qwen3 Max are proprietary and only available through APIs and apps.

Which is newer?

GPT-5.4 nano is the newest, released Mar 17, 2026. Qwen3 Max came out Sep 23, 2025. Knowledge cutoff: GPT-5.4 nano Aug 31, 2025, Qwen3 Max 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.
