Qwen Image 2.1 LoRA redistribution: notice file and Hangzhou courts

To redistribute Qwen-Image-2.1 or a derivative such as a merge or LoRA, section 3 of the Qwen Research License asks you to pass on a copy of the agreement, mark modified files with prominent change notices, and keep a Notice text file with the attribution line. Section 8 sends disputes to the People's Courts in Hangzhou City.

Clauses are quoted from the license file, read 2026-10-01; this is a summary, not legal advice. Whether a LoRA counts as a derivative work is for you or a lawyer to judge.

What must a redistribution include?

Section 3 is subject to section 2, so the non-commercial limit still applies. Within it, the conditions are listed below.

What does the Notice file say?

Clause 3(c) quotes the line to retain: "Qwen is licensed under the Qwen RESEARCH LICENSE AGREEMENT, Copyright (c) 2026 Hangzhou Tongyi Laboratory Technology Co., Ltd. All Rights Reserved." Put it in a file named as the clause says, next to your weights or adapter.

Which law and court apply?

Section 8 says the agreement is governed by the laws of China, excluding the UN Convention on Contracts for the International Sale of Goods, and that the People's Courts in Hangzhou City have exclusive jurisdiction over disputes. Section 7 lets the licensor terminate for breach, after which you must delete and stop using the Materials.

Can I run a LoRA on Sume?

The cited Sume docs describe no LoRA upload or adapter field. The image docs say a request that sets a parameter the selected model does not list is rejected with 400 unsupported_parameter, and the catalog lists qwen/qwen-image and qwen/qwen-image-max ids rather than Qwen-Image-2.1. Redistribution duties above therefore apply to what you publish yourself, not to calls to the hosted ids. Terms for the hosted ids are not stated in these clauses.
