GPT-5 vs Qwen3-Coder-Next
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
OpenAI · Aug 2025
OpenAI's August 2025 unified flagship that merged the GPT and o-series reasoning lines into one model with selectable effort.
Alibaba (Qwen) · Feb 2026
The 2026 open coding specialist: 70.6% SWE-bench Verified under Apache 2.0 from $0.11 per million input tokens.
The verdict
GPT-5 wins 1 of the 1 benchmarks these models share, against 0 for Qwen3-Coder-Next. On price the gap is dramatic: Qwen3-Coder-Next works out roughly 12x cheaper per blended million tokens. GPT-5 also takes 400K of context versus 262K for Qwen3-Coder-Next. And Qwen3-Coder-Next is open-weights (Apache 2.0), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
