Qwen3.7 Max is Alibaba's closed-weight frontier reasoning model — the first Qwen model that is proprietary rather than open-source. It targets the hardest coding, debugging, and agent orchestration tasks with chain-of-thought reasoning and a 1M context window. At $2.50/$7.50 per million tokens (often discounted 50%) it competes on price with Western frontier models. Available internationally through Alibaba Cloud Model Studio and OpenRouter. Text-only — no vision or multimodal input.
