    Qwen3-32B ships open weights (Apache-2.0); GPT-4o is API-only.

On balance GPT-4o edges ahead, winning 2 of 5 categories against Qwen3-32B's 1. GPT-4o publishes pricing ($10.00 / 1M output tokens) while Qwen3-32B does not. Both ship a 128K-token context window.

No directly comparable public benchmarks are available for both models, check the spec sheets for individual scores. They differ in modality coverage, GPT-4o handles text, vision, audio 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); GPT-4o is API-only.

Qwen3-32B is the newer of the two, released 12 months after GPT-4o, which usually means a more recent knowledge cutoff and updated safety post-training. GPT-4o is usually picked for chatbots and vision 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$22.50 vs ,
  • Heavy usage, 1M in / 500k out per day$225 vs ,
  • RAG workload, 5M in / 200k out per day$435 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).
