Qwen3 32B vs o3

o3 is the better all-round choice, scoring 58/100 against Qwen3 32B (51). It leads on capability, inputs & features and context window. Qwen3 32B wins on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Qwen3 32B is cheaper at $0.70 input / $2.80 output per million tokens (official Alibaba API price). o3 costs $2.00 input / $8.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $1.23 per million tokens for Qwen3 32B versus $3.50 for o3 (2.9× as much).

o3 scores higher on the Capabilities Index (ECI): o3 146.9 (#63 of 148) and Qwen3 32B 138.5 (#106 of 148). Their confidence ranges do not overlap (144.9–148.6 vs 135.1–140.4), so the gap is a real one. On individual benchmarks: GPQA Diamond — o3 81.8%, Qwen3 32B 65.7%; OTIS Mock AIME 2024–2025 — o3 84.4%, Qwen3 32B 66.9%.

There are no published SWE-bench Verified results for Qwen3 32B yet, so there is no like-for-like coding score. On overall capability, o3 leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.

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.
