On balance GPT-5 edges ahead, winning 3 of 5 categories against Qwen2.5-7B's 1. GPT-5 publishes pricing ($10.00 / 1M output tokens) while Qwen2.5-7B does not. GPT-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 handles text, vision, audio while Qwen2.5-7B handles text, which can be the deciding factor before you even look at benchmarks. Qwen2.5-7B ships open weights (Apache-2.0); GPT-5 is API-only.
GPT-5 is the newer of the two, released 11 months after Qwen2.5-7B, which usually means a more recent knowledge cutoff and updated safety post-training. GPT-5 is usually picked for coding llm and agents workloads, while Qwen2.5-7B sees more deployments in local llm and on device. 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$18.75 vs ,
- Heavy usage, 1M in / 500k out per day$188 vs ,
- RAG workload, 5M in / 200k out per day$248 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.
