GPT-5.5 vs Qwen3.7-Max

GPT-5.5 and Qwen3.7-Max are frontier closed-weight agentic models with 1m-token context windows. GPT-5.5 brings stronger terminal-agent results and vision input; Qwen3.7-Max brings lower tracked token prices and a small SWE-bench Pro edge for repository-scale coding.

Pick GPT-5.5 for terminal-heavy agents, tool orchestration, and multimodal workflows: it leads Terminal-Bench 2.0 at 82.7% versus 69.7% and supports image input. Pick Qwen3.7-Max when repository-scale coding and token cost matter more: it leads SWE-bench Pro at 60.6% versus 58.6%, and OpenRouter currently lists a 50% promotional rate of $1.25/M input and $3.75/M output. Treat Qwen3.7-Max pricing as freshness-sensitive because Alibaba's official pricing page did not list the 3.7 series at integration time.

Switch friction

GPT-5.5 -> Qwen3.7-Max
  • Provider overlap exists on Vercel AI Gateway and OpenRouter; start route-level A/B tests there.
  • Qwen3.7-Max is $26.25/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
  • Check replacement coverage for Vision and Multimodal before moving production traffic.
