## Summary

[Alibaba](/fr/entity/alibaba-qwen) split its Qwen line by tier in mid-2026. Qwen3.7-Max, unveiled at the Apsara Summit on 20 May, is the proprietary flagship; Qwen3.7-Plus, a multimodal agent variant at roughly one-sixth the per-token cost, followed on 1 June. Both are API-only via Alibaba Cloud, not open-weight. The open-weight Qwen 3.6 series stays on Apache 2.0, with Qwen3.6-35B-A3B the open top pick. The structure mirrors a broader bet: open lower tiers seed global adoption while proprietary flagships monetise via cloud. It sets Alibaba against fully open [DeepSeek V4](/fr/n/deepseek-v4-open-weights-2026) inside China and feeds the [open-vs-closed](/fr/n/open-vs-closed-frontier-2026) contest.

## By the numbers

- 20 May 2026, Qwen3.7-Max unveiled (proprietary).
- 1 Jun 2026, Qwen3.7-Plus agent variant (proprietary, ~1/6 cost).
- 1M tokens, Qwen 3.7 context.
- Apache 2.0, licence on the open Qwen 3.6 line.

## Why it matters

Alibaba is hedging the open-vs-closed question: keep the frontier proprietary to drive cloud revenue, keep a strong open tier to hold developer mindshare and counter DeepSeek. The tiering shows the Chinese majors diverging on openness even as both press the agent frontier.

## What to watch

- Whether a Qwen 3.7 open-weight tier ever ships.
- Qwen 3.7 agent benchmarks vs. DeepSeek V4 and US models.
- Alibaba Cloud's AI revenue trajectory off the proprietary tier.
