    GPT-5.5 supports 3 modalities (text, vision, audio) vs 1 for Qwen3-32B.

  • OpennessQwen3-32B

    Qwen3-32B ships open weights (Apache-2.0); GPT-5.5 is API-only.

On balance GPT-5.5 edges ahead, winning 2 of 5 categories against Qwen3-32B's 1. Neither model publishes per-token API pricing. GPT-5.5 accepts 400K tokens vs 128K, 3.1× 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, GPT-5.5 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-5.5 is API-only.

GPT-5.5 is the newer of the two, released 10 months after Qwen3-32B, which usually means a more recent knowledge cutoff and updated safety post-training. GPT-5.5 is usually picked for agents and tool use workloads, while Qwen3-32B sees more deployments in open source llm and edge deployment.

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).
