  • Modalitieso4

    o4 supports 2 modalities (text, vision) vs 1 for Qwen3-72B.

  • OpennessQwen3-72B

    Qwen3-72B ships open weights (Apache-2.0); o4 is API-only.

On balance o4 edges ahead, winning 2 of 5 categories against Qwen3-72B's 1. Neither model publishes per-token API pricing. o4 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 handles text, vision 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); o4 is API-only.

o4 is the newer of the two, released 8 months after Qwen3-72B, which usually means a more recent knowledge cutoff and updated safety post-training. o4 is usually picked for reasoning and math workloads, while Qwen3-72B sees more deployments in open source llm and commercial use llm. 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, vs ,
  • Heavy usage, 1M in / 500k out per day, vs ,
  • RAG workload, 5M in / 200k out per day, 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).
