Qwen3-Coder-Next review 2026: 80B params, 3B active, and the cheapest credible coding agent API

This article was originally published on aicoderscope.com

TL;DR: Qwen3-Coder-Next (80B total, 3B active) scores 70.6% on SWE-bench Verified — compelling for an open-weight model — but the leaderboard has moved significantly since its February launch. Its real value proposition in May 2026 is cost: at $0.11/M input tokens, it's the cheapest credible coding agent API by a wide margin, and on local hardware it runs on a single 24GB GPU with system RAM offloading.
