GPT-5.1 vs Qwen3 14B
GPT-5.1 leads Qwen3 14B on the Artificial Analysis Intelligence Index, 24.7 to 6.7, and Qwen3 14B costs 43.5x less per output token ($0.23 vs $10.00 per million). Updated October 22, 2026; 16 benchmarks have a result for both.
GPT-5.1 or Qwen3 14B: which to pick
Only GPT-5.1 has a coding score, 40.4 on the Vibe Coding Index; Qwen3 14B has none, so the two cannot be ranked on coding.
Pick Qwen3 14B for output tokens 43.5x cheaper ($0.23 vs $10.00 per million).
