On balance GPT-4o edges ahead, winning 3 of 5 categories against Qwen3-72B's 1. GPT-4o publishes pricing ($10.00 / 1M output tokens) while Qwen3-72B does not. Both ship a 128K-token context window.
GPT-4o leads in 1 of 1 shared benchmarks; the biggest gap is on MMLU (broad academic knowledge), where it scores 88.7 vs 84.0. They differ in modality coverage, GPT-4o handles text, vision, audio while Qwen3-72B handles text, which can be the deciding factor before you even look at benchmarks. Qwen3-72B ships open weights (Apache-2.0); GPT-4o is API-only.
Qwen3-72B 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 Qwen3-72B sees more deployments in open source llm and commercial use llm.

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).
