Qwen3.7-Max

Qwen3.7-Max is Alibaba's May 2026 flagship model, landed on the Alibaba Cloud API on May 19 and unveiled at the 2026 Cloud Summit on May 20. At $2.50 per million input and $7.50 per million output tokens, with a 1,000,000 token context window and up to 65,536 output tokens, it carries an extended-thinking mode and claims of autonomous operation for up to 35 hours on long-horizon agentic tasks. Posted the top result on the public Artificial Analysis Intelligence Index at 57 and roughly 1,475 Elo on the LM Arena text leaderboard at release. Cached input drops to $0.25 per million tokens via OpenRouter, a 90 percent discount that makes repeated long-context calls dramatically cheaper.
