+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and
+conditions that creators and other rights holders may use to share
+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or
+     limitation to copyright. More considerations for licensors:

+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to

+     reasons, including because others have copyright or other

+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More considerations

+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part, for NonCommercial purposes only; and
+
+            b. produce, reproduce, and Share Adapted Material for
+               NonCommercial purposes only.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties, including when
+          the Licensed Material is used other than for NonCommercial
+          purposes.
+
+
+Section 3 -- License Conditions.

+          reasonably practicable.
+

+     In addition to the conditions in Section 3(a), if You Share
+     Adapted Material You produce, the following conditions also apply.
 
-Core Statement: The Model is fine-tuned based on the Qwen3 base weights (copyright owned by the Qwen Team), and the Qwen3 base weights are subject to the Apache License 2.0. As a derivative work, the Model adopts a "Dual License" mechanism, meaning it may be freely used for non-commercial purposes, while commercial use requires separate permission from the Licensor. At the same time, the core obligations and attribution requirements of the Apache License 2.0 must be complied with throughout.
+       1. The Adapter's License You apply must be a Creative Commons
+          license with the same License Elements, this version or
+          later, or a BY-NC-SA Compatible License.
 
-I. Source of Base Weights and Obligations under the Original Agreement
+       2. You must include the text of, or the URI or hyperlink to, the
+          Adapter's License You apply. You may satisfy this condition
+          in any reasonable manner based on the medium, means, and

-- Retain all contents of the original Qwen3 copyright notice, patent license notice, and NOTICE file without modification or deletion;
+Section 4 -- Sui Generis Database Rights.
 
-- If making secondary modifications to the Model, clearly mark "Modified" along with the modification date and content in the modified files;
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
 
-- Provide the complete text of this Agreement and the Apache License 2.0 to any third party receiving the Model.
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database for NonCommercial purposes
+     only;
 
-II. Core Rules of Dual License
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material,
+     including for purposes of Section 3(b); and
 
-The right to use the Model is divided into two categories based on the usage scenario: "Non-Commercial Use" and "Commercial Use". The specific rules are as follows:
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
 
-(I) Authorization for Non-Commercial Use
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
 
-1. Scope of Authorization: The Licensee may freely obtain, use, modify, and redistribute the Model (including fine-tuned derivative weights) for non-commercial and non-profit purposes without prior application for authorization from the Licensor.

+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,

+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
 
-- Using the Model for commercial advertising, marketing promotion, or related services;
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,

+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR

+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
 
-- Providing paid consulting, training, or deployment services based on the Model to third parties;
+  c. The disclaimer of warranties and limitation of liability provided

-- Other profit-oriented usage behaviors.
 
-1. Additional Obligations for Non-Commercial Use: When using or redistributing the Model for non-commercial purposes, the Licensee must mark the complete attribution information in a prominent location (e.g., project README, product description document) (see Article 3 of this Agreement for specific requirements).
+Section 6 -- Term and Termination.
 
-(II) Authorization for Commercial Use
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with

+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:

+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop

+     will not terminate this Public License.
 
-1. Principle of Authorization: For commercial use of the Model, the Licensee must submit a written application to the Licensor in advance and obtain a "Commercial Authorization Certificate". Unauthorized commercial use will entitle the Licensor to pursue legal liability.
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.

-
-IV. Other Core Restrictions
-
-1. The Licensee shall not use the Model for any illegal, irregular, or public order-disrupting scenarios, including but not limited to: malicious cyber attacks, disinformation generation, infringement of others' privacy/intellectual property rights, endangering national security, etc. In the event of such behavior, the Licensor has the right to terminate the authorization, and the Licensee shall bear full legal liability.
-
-2. For derivative weights generated by secondary modifications to the Model, the Licensee must adopt the "Dual License" mechanism of this Agreement, and shall not independently change the authorization method to "completely prohibit commercial use" or "unrestricted commercial use". At the same time, the original attribution information and the text of this Agreement must be retained.
-
-3. The Licensor makes no express or implied warranties regarding the applicability, accuracy, or safety of the Model. The Licensor shall not be liable for any direct or indirect losses incurred by the Licensee due to the use of the Model.
