Which should you choose?
Which is better: Qwen3.7 Plus or GPT-6 Luna?
GPT-6 Luna is the better all-round choice, scoring 84/100 against Qwen3.7 Plus (68). It leads on capability and price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%. Capability uses the average of shared benchmarks (GPQA Diamond, FrontierMath Tiers 1–3 and OTIS Mock AIME 2024–2025), because GPT-6 Luna has no Capabilities Index score yet.
Which is cheaper, Qwen3.7 Plus or GPT-6 Luna?
GPT-6 Luna is cheaper at $0.10 input / $0.50 output per million tokens (official OpenAI API price). Qwen3.7 Plus costs $0.40 input / $1.60 output per million tokens (official Alibaba API price). At a typical mix of three input tokens to one output token, that is $0.20 per million tokens for GPT-6 Luna versus $0.70 for Qwen3.7 Plus (3.5× as much).
Which scores higher on benchmarks?
Not every model here has a Capabilities Index score, so we compare the average of shared benchmarks (GPQA Diamond, FrontierMath Tiers 1–3 and OTIS Mock AIME 2024–2025): GPT-6 Luna 89.4% and Qwen3.7 Plus 71.9%. On individual benchmarks: GPQA Diamond — GPT-6 Luna 90.5%, Qwen3.7 Plus 87.9%; FrontierMath Tiers 1–3 — GPT-6 Luna 79.0%, Qwen3.7 Plus 34.4%; OTIS Mock AIME 2024–2025 — GPT-6 Luna 98.9%, Qwen3.7 Plus 93.3%.
Which is better for coding?
There are no published SWE-bench Verified results for Qwen3.7 Plus and GPT-6 Luna yet, so there is no like-for-like coding score. On overall capability, GPT-6 Luna leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.
Which has the bigger context window?
GPT-6 Luna has the largest context window at 1,050,000 tokens, against 1,000,000 for Qwen3.7 Plus. Maximum output per response: Qwen3.7 Plus up to 64,000, GPT-6 Luna up to 128,000 tokens.
Which can read images, PDFs, audio or video?
Qwen3.7 Plus accepts text, images and video; GPT-6 Luna accepts text, images and PDFs. They handle the same number of input types.
Are any of these open source?

Which is newer?
GPT-6 Luna is the newest, released Sep 22, 2026. Qwen3.7 Plus came out Jun 2, 2026. Knowledge cutoff: Qwen3.7 Plus Apr 2025, GPT-6 Luna May 18, 2026.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
