On balance o4-mini edges ahead, winning 3 of 5 categories against Qwen3-32B's 1. o4-mini publishes pricing ($4.40 / 1M output tokens) while Qwen3-32B does not. o4-mini accepts 200K tokens vs 128K, 1.6× the room for long documents and codebases.
No directly comparable public benchmarks are available for both models, check the spec sheets for individual scores. They differ in modality coverage, o4-mini handles text, vision while Qwen3-32B handles text, which can be the deciding factor before you even look at benchmarks. Qwen3-32B ships open weights (Apache-2.0); o4-mini is API-only.
Both shipped within roughly a month of each other in 2025, so they share the same generation of training data and tooling. o4-mini is usually picked for reasoning and math workloads, while Qwen3-32B sees more deployments in open source llm and edge deployment. If pricing matters more than every last benchmark point, run the numbers in the calculator below before committing.

Pricing at scale
What you'd actually pay at typical workloads. Numbers come from each model's published per-million-token rates.
- Light usage, 100k in / 50k out per day$9.90 vs ,
- Heavy usage, 1M in / 500k out per day$99.00 vs ,
- RAG workload, 5M in / 200k out per day$191 vs ,
Light usage, 100k in / 50k out per day: pricing not directly comparable (one or both models are missing public per-token rates). Heavy usage, 1M in / 500k out per day: pricing not directly comparable (one or both models are missing public per-token rates). RAG workload, 5M in / 200k out per day: pricing not directly comparable (one or both models are missing public per-token rates).
Estimated spend for the listed models at your usage. Numbers are derived from each model's published per-million-token rates.
