Grok 4.1 Fast vs Qwen3-Coder-Next
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
xAI · Nov 2025
A 2M-token context window for $0.20 per million input tokens — the cheapest long-context frontier offering anywhere.
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
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. Grok 4.1 Fast is about 1.0x cheaper per blended million tokens (3:1 input:output mix). Grok 4.1 Fast also takes 2M 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.
