GPT-5.5 vs Qwen3-Coder-Next

Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.

GPT-5.5

OpenAI · Apr 2026

77.2

OpenAI's flagship reasoning model with a 1M-token context window, built for hard coding, science and long-horizon agentic work.

Qwen3-Coder-Next

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-5.5 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 40x cheaper per blended million tokens. GPT-5.5 also takes 1M 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.
