Qwen3.7 Plus vs GPT-5.1: which should you choose?
Qwen3.7 Plus — Alibaba multimodal model with an Intelligence Index of 39, a 1M-token context window and a blended price of $0.26/1M tokens (open weights).
GPT-5.1 — OpenAI multimodal model with an Intelligence Index of 37, a 512K-token context window and a blended price of $0.77/1M tokens.
Qwen3.7 Plus vs GPT-5.1: Qwen3.7 Plus scores higher on the Intelligence Index. Qwen3.7 Plus leads overall capability (Intelligence Index 39.0 vs 37.0). Qwen3.7 Plus is the cheaper model to run at $0.26/1M blended tokens — about 3.0× cheaper.
Capability: intelligence, coding and agentic work
On the composite Intelligence Index the Qwen3.7 Plus scores 39.0 versus 37.0. For software development, the Coding Index puts Qwen3.7 Plus ahead (55.9 vs 49.4). On agentic, multi-step tool-use tasks, GPT-5.1 measures stronger. Composite indices summarize many evaluations, but always test on your own workload before committing.
Context window and speed
The Qwen3.7 Plus accepts up to 1 million tokens per request, which sets how much documentation, transcript or code it can reason over at once. In measured throughput, GPT-5.1 generates faster (106 vs 53 tokens/s), which matters for interactive apps and high-volume pipelines.
Pricing and access
At blended per-token rates, Qwen3.7 Plus is the cheaper model to run ($0.26 vs $0.77 per 1M tokens). Qwen3.7 Plus is open weights and GPT-5.1 is proprietary api. Open-weight models can be self-hosted, trading per-call cost for infrastructure you manage; for production also weigh rate limits, throughput and data-residency requirements.
The verdict
Both are credible choices in the ai model comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Large language models are compared on independent leaderboard metrics: an Intelligence Index (a composite of reasoning and knowledge evaluations), Coding and Agentic indices where measured, community arena Elo, maximum context window, a blended API price per million tokens (weighted across cache-hit, input and output rates), and measured output speed in tokens per second. Where a model ships multiple reasoning-effort variants, we report its strongest variant. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit — and this space moves quickly, so figures reflect the leaderboard snapshot on the page date.
