1 BOSON HIGGS TTS 3 RESEARCH AND NON-COMMERCIAL LICENSE AGREEMENT
2
3 Last Updated: July 8, 2026
4
5 I. INTRODUCTION
6
7 This License Agreement (the "Agreement") is entered into by and between Licensee (as defined below) and Boson AI USA, Inc. ("Boson", "we", or "us"). This Agreement governs Your use, reproduction, distribution, and modification of the Higgs Materials.
8
9 This Agreement is intended to allow Research and Non-Commercial use of the Higgs Materials free of charge. Any Commercial use of the Higgs Materials requires a separate written license from Boson. As a limited exception, Boson also grants digital creators a free, royalty-free license to create and publish creative content using the Higgs Materials, including monetized creative content, subject to an attribution requirement, as set forth in Section II-A (Creator Use Grant). For clarity, this Agreement is a research and non-commercial source-available model license and is not an open source license.
10
11 The Higgs Materials may incorporate third-party components made available under their own open source licenses. Your obligations under those third-party licenses (including, where applicable, the retention of upstream copyright, patent, trademark, and attribution notices) are addressed in a separate "NOTICE" file accompanying the Higgs Materials and are in addition to Your obligations under this Agreement. This Agreement governs the Higgs Materials and any Derivative Work as a whole.
12
13 By clicking "I Accept", or by accessing, using, or distributing any portion or element of the Higgs Materials or any Derivative Work, You agree that You have read, understood, and are bound by the terms of this Agreement. If You are acting on behalf of an entity, You represent that You are authorized to bind that entity, and "You" includes both you and that entity.
14
15 II. RESEARCH AND NON-COMMERCIAL USE LICENSE
16
17 Subject to the terms of this Agreement, Boson grants You a non-exclusive, worldwide, non-transferable, non-sublicensable, royalty-free, limited license (terminable as set forth in Section IV(h)) under Boson's intellectual property rights embodied in the Higgs Materials to use, reproduce, distribute, copy, create Derivative Works of, and make modifications to the Higgs Materials solely for a Research Purpose or a Non-Commercial Purpose.
18
19 "Research Purpose" means academic or scientific advancement that is not primarily intended for commercial advantage or monetary compensation to You or others, including peer-reviewed publication, benchmarking, and reproducibility studies. For clarity, Research Purpose may include non-production benchmarking, evaluation, security testing, and red-teaming by commercial entities, in each case to the extent expressly permitted in Section III.
20
21 "Non-Commercial Purpose" means any purpose other than a Research Purpose that is not primarily intended for commercial advantage or monetary compensation, such as personal use (i.e., hobbyist projects) or short-term evaluation and testing.
22
23 II-A. CREATOR USE GRANT (FREE FOR DIGITAL CREATORS)
24
25 In addition to the license in Section II, and notwithstanding Section III, Boson grants Digital Creators a non-exclusive, worldwide, non-transferable, non-sublicensable, royalty-free, limited license (terminable as set forth in Section IV(h)) under Boson's intellectual property rights embodied in the Higgs Materials to use the Higgs Materials to create, reproduce, publish, distribute, and monetize Creator Content, subject to the terms of this Agreement (including the Use Restrictions in Section IV(b) and the Acceptable Use Policy) and to the Creator Acknowledgment requirement in Section II-A(b).
26
27 a. What is covered. This grant covers using the Higgs Materials to generate audio for creative works — including podcasts, videos, audiobooks, social media posts, and similar creative content — and publishing and monetizing that content on channels You own or control, whether personal or commercial, including ad-supported, sponsored, subscription, or otherwise monetized creator channels.
28
29 b. Creator Acknowledgment (the one requirement). For any Creator Content You publish under this grant, You must acknowledge Boson AI's Higgs Audio in at least one of the following ways:
30
31 (i) In the audio itself — for example, "This audio was created with Boson AI's Higgs Audio."; or
32
33 (ii) In the accompanying text, displayed prominently together with the content — such as the post body, video description, episode description, or show notes. The acknowledgment must be clearly visible to the audience and must not be hidden or buried at the bottom of the credits or annotations.
34
35 A suggested acknowledgment string is:
36
37 "This audio was created with Boson AI's Higgs Audio — https://www.boson.ai/higgs-audio"
38
39 For Creator Content published under this grant, providing this Creator Acknowledgment satisfies Your attribution obligations under Section IV(a) with respect to that Creator Content. The naming and no-endorsement limitations in Sections IV(a)(iv) and IV(d)(i) continue to apply.
40
41 c. What this grant does not cover. This grant covers creating and publishing Creator Content. It does not cover, and a separate written commercial license from Boson is required for, each of the following:
42
43 (i) hosting, serving, or otherwise making the Higgs Materials available to others, whether via an API, SaaS offering, plug-in, hosted tool, or end-user application;
44
45 (ii) redistributing, reselling, sublicensing, or otherwise distributing the Higgs Materials or any Derivative Work, or fine-tuning, distilling, or otherwise creating a Derivative Work for resale or distribution; and
46
47 (iii) embedding or integrating the Higgs Materials in a product, application, or service made available to third parties (including a text-to-speech, voice-generation, dubbing, or content-creation product or service).
48
49 For these uses, please contact Boson at https://boson.ai or contact@boson.ai for a commercial license.
50
51 d. Relationship to other terms. This grant is a limited exception to Section III and does not otherwise expand Your rights. All other terms of this Agreement apply to Your use of the Higgs Materials and Your Creator Content, including the Use Restrictions in Section IV(b) (for example, the prohibitions on non-consensual voice cloning and impersonation, deceptive or fraudulent use, and undisclosed synthetic content where disclosure is required), the representations and warranties in Section IV(c), and the disclaimers and limitations of liability in Sections IV(f) and IV(g). Nothing in this grant relieves You of any consent, disclosure, or labeling obligation under Section IV(b) or applicable law. If any Creator Content or related use falls outside the scope of this grant, it remains subject to Section III and may require a separate commercial license.
52
53 III. COMMERCIAL USE
54
55 Except as expressly permitted under Section II-A (Creator Use Grant), any use of the Higgs Materials, Derivative Works, or any output generated using the foregoing for a Commercial Purpose requires a separate written license agreement from Boson. No commercial rights are granted under this Agreement except as expressly set forth in Section II-A.
56
57 "Commercial Purpose" means any purpose that is primarily intended for or directed toward commercial advantage or monetary compensation to You or others, including but not limited to: (i) production use, hosted use (including via an API, SaaS offering, plug-in, or end-user application), or any use made available to end users outside Your organization; (ii) any use in connection with a product or service for which You charge a fee, sell advertising, or otherwise generate revenue, whether directly or indirectly; (iii) Your or Your Affiliate's internal business or organizational operations beyond limited evaluation as permitted below; and (iv) any use described in Section IV(b)(i) (model training, fine-tuning, distillation, or improvement of non-Boson models), which is independently prohibited by that section absent a separate written agreement with Boson. Notwithstanding the foregoing, the creation, publication, and monetization of Creator Content by a Digital Creator is permitted without a separate commercial license to the extent expressly authorized by, and in compliance with, Section II-A.
58
59 For clarity, limited internal evaluation, benchmarking, security testing, or red-teaming of the Higgs Materials by a for-profit entity is permitted as a Research Purpose or Non-Commercial Purpose, provided that such use is (a) not deployed in production, (b) not made available to end users or customers, (c) not used to generate revenue, and (d) not used to train, fine-tune, distill, or improve any non-Boson model. Your status as a for-profit entity (including the amount of funding You have raised or revenue You have generated) does not, by itself, make Your use a Commercial Purpose.
60
61 For further clarity, the publication of research results, benchmark outputs, illustrative samples, or non-commercial demonstrations in academic papers, research reports, conference talks, blog posts, public model cards, or non-commercial repositories is not a Commercial Purpose solely because such materials are made publicly accessible, provided that such use (a) is not monetized, (b) is not used to provide a product or service, and (c) complies with the Acceptable Use Policy and the Use Restrictions in Section IV(b). Outputs generated solely for permitted evaluation, benchmarking, academic research, security testing, red-teaming, or non-commercial demonstration may be retained, displayed, and distributed as part of such permitted activity, provided they are not monetized, used in a product or service, or used to train, fine-tune, distill, or improve non-Boson models.

68 IV. GENERAL TERMS
69
70 Your license under this Agreement is subject to the following terms.
71
72 a. Distribution and Attribution.
73
74 If You distribute or make available the Higgs Materials or any Derivative Work to a third party, or make available any permitted non-commercial application, demonstration, repository, or service that uses any portion of the foregoing, You shall:
75
76 (i) provide a copy of this Agreement to that third party, together with any NOTICE file that accompanies the Higgs Materials;
77
78 (ii) retain the following attribution notice within a "NOTICE" text file distributed as part of such copies:
79
80 "Boson Higgs TTS 3 is licensed under the Boson Higgs TTS 3 Research and Non-Commercial License, Copyright (c) Boson AI USA, Inc. All Rights Reserved.";
81
82 (iii) for public-facing applications or demonstrations, make a reasonable attribution such as:
83
84 "Built with Higgs TTS 3 licensed from Boson AI USA, Inc.";
85
86 For repositories, model cards, papers, reports, or technical documentation, attribution in the README, model card, NOTICE file, or equivalent documentation is sufficient; and
87
88 (iv) if You create, modify, fine-tune, distill, or otherwise improve any AI model or software using the Higgs Materials and distribute or make it available, You shall state in the model card, documentation, repository description, and distribution page that the model or software is "Derived from Higgs TTS 3, licensed from Boson AI USA, Inc." You shall not use "Higgs TTS 3" (or any confusingly similar name, including without limitation "Higgs TTS 4", "Higgs Pro", or "Boson TTS") as the leading or primary element of Your model or software name, or otherwise in a manner that suggests official status, endorsement by, affiliation with, or successor status to Boson.
89
90 For clarity, a Digital Creator publishing Creator Content under Section II-A satisfies its attribution obligations by providing the Creator Acknowledgment described in Section II-A(b), and is not required to reproduce the NOTICE file or Agreement alongside individual items of published Creator Content.
91
92 If You create a Derivative Work, You may add Your own attribution notices to the "NOTICE" text file, provided You clearly indicate which attributions apply to the Higgs Materials and state that You changed the Higgs Materials and how You modified them.
93
94 b. Use Restrictions.
95
96 Your use of the Higgs Materials and any Derivative Work, including any output or results thereof, must comply with all applicable laws and regulations (including Trade Control Laws) and must adhere to the Acceptable Use Policy, which is incorporated by reference into this Agreement. Updates to the Acceptable Use Policy apply prospectively and will not retroactively terminate rights for prior compliant use, except where reasonably necessary to address legal compliance, security, fraud, abuse, or safety risks.
97
98 You will not, and will not permit any third party to:
99
100 (i) use the Higgs Materials, Derivative Works, or any output or results thereof to create, train, fine-tune, distill, or improve any foundational generative AI model, large language model, audio model, speech model, or other machine-learning model that is intended to generate, synthesize, clone, transform, or materially improve speech, audio, language, or multimodal generation capabilities (excluding Higgs TTS 3 itself and Derivative Works thereof for permitted purposes), unless expressly authorized in a separate written agreement with Boson. For clarity, this restriction does not prohibit the creation or use of non-generative classifiers, evaluators, safety filters, watermark or provenance detectors, or benchmark tools solely for permitted Research or Non-Commercial Purposes, provided that (a) they are not used, directly or indirectly, to train, fine-tune, distill, or improve any non-Boson generative model, and (b) they are not designed or intended to enable, accelerate, or contribute to the development of any audio, speech, language, or multimodal generation system by You or any third party;
101
102 (ii) use the Higgs Materials or any output to generate audio that impersonates, clones, simulates, or imitates any real person (including their voice, name, likeness, or persona) without that person's explicit, verifiable consent, which may include written or legally valid electronic consent. You may not submit or use reference audio, speaker embeddings, voice prompts, or other materials for voice cloning or voice adaptation unless You have all necessary rights, licenses, and consents for such use. For public-facing, commercial, telephony, political, endorsement, or other high-risk uses, You must maintain records sufficient to demonstrate such consent and produce them on Boson's reasonable request;
103
104 (iii) use the Higgs Materials or any output to create content intended to defraud, harass, stalk, threaten, defame, or deceive any person;
105
106 (iv) use the Higgs Materials or any output to generate audio depicting any minor in any sexual, exploitative, or otherwise harmful context;
107
108 (v) use the Higgs Materials or any output for (A) deceptive political persuasion, election-related deception, campaign impersonation, voter suppression, or synthetic robocalls; or (B) generating audio that falsely depicts, simulates, or attributes statements to any political candidate, elected official, government official, party representative, or other public figure, unless You have that person's explicit prior authorization and provide all legally required disclosures (including, where applicable, clear and conspicuous labeling that the content is synthetic). For the avoidance of doubt, subsection (B) is not intended to prohibit bona fide journalism, commentary, education, scholarship, parody, or satire that does not falsely present synthetic content as authentic;
109
110 (vi) use the Higgs Materials, Derivative Works, or any output or results thereof to identify, verify, authenticate, track, surveil, or profile any person based on voice or other biometric characteristics, except with a lawful basis and the explicit consent required by applicable law;
111
112 (vii) make public-facing synthetic audio, telephony, advertising, political, endorsement, or other high-risk content without clear and conspicuous disclosure that the content is AI-generated or synthetic where required by law or where a reasonable person would otherwise be misled;
113
114 (viii) remove, obscure, alter, or fail to reproduce any copyright, trademark, attribution, watermark, provenance signal, or other proprietary notice included in or output by the Higgs Materials;
115
116 (ix) reverse engineer, decompile, or otherwise attempt to extract non-public components, training data, source data, trade secrets, or proprietary information from the Higgs Materials, except to the extent such restriction is prohibited by applicable law. For the avoidance of doubt, this restriction does not prohibit ordinary inspection, loading, conversion, quantization, fine-tuning, or other use of the model weights as made available by Boson under this Agreement; or
117
118 (x) bring any legal action, claim, charge, or demand challenging Boson's ownership of, or rights in, the Higgs Materials.
119
120 No Third-Party Rights Granted. This Agreement does not grant You any rights to use, reproduce, clone, simulate, imitate, or otherwise exploit any third-party voice, likeness, name, image, persona, performance, recording, copyrighted work, or other protected content. You are solely responsible for obtaining all rights, licenses, consents, and permissions required for any reference audio, speaker embedding, prompt, input, output, and any downstream use thereof. Nothing in the Higgs Materials or any output thereof shall be construed as a representation or warranty that any voice, likeness, recording, copyrighted work, or other content embedded in or generated by the Higgs Materials is cleared for Your intended use. This paragraph applies to Creator Content published under Section II-A to the same extent as to any other use.
121
122 c. Representations and Warranties.
123
124 You represent and warrant that: (i) You are of the age required by applicable law to enter into this Agreement and, if acting on behalf of an entity, are authorized to bind that entity; (ii) neither You nor any party that owns or controls You is listed on any U.S. or other applicable government list of prohibited or restricted parties, and You are not located in, organized under the laws of, or ordinarily resident in any country or territory subject to comprehensive U.S. trade sanctions; (iii) You will not knowingly make the Higgs Materials or any Derivative Work available to any party listed on any U.S. or other applicable government list of prohibited or restricted parties, and will use commercially reasonable measures to prevent such access by parties You know or reasonably should know to be so listed; (iv) You will not use the Higgs Materials in connection with the design, development, production, or use of nuclear, chemical, or biological weapons, or missile technology; and (v) all information You provide to Boson in connection with this Agreement is true, accurate, and complete.
125
126 d. Intellectual Property.
127
128 (i) Trademark License. No trademark licenses are granted under this Agreement. Neither Boson nor Licensee may use any name or mark owned by, or associated with, the other party or any of its Affiliates, except as required to comply with Section IV(a) or as expressly permitted for the Creator Acknowledgment in Section II-A(b). Boson hereby grants You a limited, non-exclusive, non-transferable license to use "Higgs TTS 3" and "Boson AI's Higgs Audio" (the "Mark") solely as a descriptive reference required to comply with the attribution and notice obligations in Sections IV(a)(ii)-(iv) and the Creator Acknowledgment in Section II-A(b), and not as the leading or primary name of any product, model, or service. All goodwill arising out of Your use of the Mark inures to the benefit of Boson.
129
130 (ii) Ownership of Derivative Works. Subject to Boson's ownership of the Higgs Materials and any Derivative Works made by or for Boson, and subject to the restrictions in this Agreement, as between You and Boson, You are the owner of any Derivative Works You create.
131
132 (iii) Ownership of Outputs. As between You and Boson, You own the outputs generated from the Higgs Materials or Derivative Works to the extent permitted by applicable law, provided that Boson grants no rights in any output generated in violation of this Agreement. Boson makes no representation that any output is non-infringing or fit for any purpose, and You are solely responsible for Your use of any output.
133
134 (iv) Disputes. If You or Your Affiliate institutes litigation or other proceedings against Boson or any of Boson's licensees, customers, or end users (including a cross-claim or counterclaim in a lawsuit) alleging that the Higgs Materials, Derivative Works, or any output or results thereof, or any portion of any of the foregoing, constitutes infringement of intellectual property or other rights owned or licensable by You, then any licenses granted to You under this Agreement shall terminate automatically as of the date such litigation or claim is filed or instituted. You will indemnify, defend, and hold harmless Boson and its Affiliates, officers, directors, employees, and agents from and against any claim, charge, demand, loss, or cause of action by any third party arising out of or related to Your use or distribution of the Higgs Materials or Derivative Works, Your outputs, or Your breach of this Agreement.
135
136 (v) Feedback. From time to time, You may provide Boson with verbal or written suggestions, comments, ideas, or other feedback related to Boson's existing or prospective technology, products, or services (collectively, "Feedback"). You are not obligated to provide Feedback, but to the extent You do, You hereby grant Boson a perpetual, irrevocable, royalty-free, fully paid-up, sublicensable, transferable, non-exclusive, worldwide right and license to use, reproduce, distribute, modify, and otherwise exploit the Feedback in any manner without restriction. All Feedback is provided "AS IS" and You make no warranties regarding any Feedback.
137
138 e. Audit and Reporting.
139
140 This Section IV(e) applies only to Licensees that (i) distribute or make available the Higgs Materials or any Derivative Work to third parties, (ii) make the Higgs Materials or any Derivative Work available as part of a hosted demonstration, service, or product, or (iii) Boson reasonably believes are using the Higgs Materials for a Commercial Purpose without a commercial license. It does not apply to individual hobbyist or personal Non-Commercial use, or to a Digital Creator's creation and publication of Creator Content within the scope of Section II-A.
141
142 For Licensees within the scope above, Boson reserves the right, no more than once per calendar year and upon reasonable prior written notice, to request a written report describing Your use of the Higgs Materials and Derivative Works, including the purposes of such use and the approximate number of users or end users (if any). You shall respond to any such request within thirty (30) days. If, following such request, Boson reasonably believes You are using the Higgs Materials for a Commercial Purpose without a commercial license, Boson may require You to either (i) cease such use, or (ii) enter into a commercial license on then-current terms.
143
144 f. Disclaimer of Warranty.
145
146 UNLESS REQUIRED BY APPLICABLE LAW, THE HIGGS MATERIALS AND ANY OUTPUT AND RESULTS THEREFROM ARE PROVIDED ON AN "AS IS" BASIS, WITH ALL FAULTS, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. BOSON DISCLAIMS ALL WARRANTIES, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND ANY WARRANTY THAT THE HIGGS MATERIALS WILL BE UNINTERRUPTED OR ERROR-FREE. YOU ARE SOLELY RESPONSIBLE FOR DETERMINING THE APPROPRIATENESS AND LAWFULNESS OF USING OR REDISTRIBUTING THE HIGGS MATERIALS AND ASSUME ANY AND ALL RISKS ASSOCIATED WITH SUCH USE.
147
148 g. Limitation of Liability.
149
150 IN NO EVENT WILL BOSON OR ITS AFFILIATES BE LIABLE UNDER ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, PRODUCTS LIABILITY, OR OTHERWISE, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE HIGGS MATERIALS, FOR ANY LOST PROFITS, LOST REVENUE, LOSS OF DATA, COST OF SUBSTITUTE GOODS, OR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, INCIDENTAL, EXEMPLARY, OR PUNITIVE DAMAGES, EVEN IF BOSON OR ITS AFFILIATES HAVE BEEN ADVISED OF THE POSSIBILITY OF ANY OF THE FOREGOING. IN ANY EVENT, BOSON'S AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT SHALL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US$100).
151
152 h. Term and Termination.
153
154 The term of this Agreement commences upon Your acceptance of this Agreement or first access to the Higgs Materials and continues until terminated. Boson may terminate this Agreement upon Your breach of any term of this Agreement, Your violation of the Acceptable Use Policy, or Your violation of applicable law, in each case by providing You written notice (which may include notice posted at https://boson.ai or in the Higgs Materials repository). For material breaches that are capable of cure, Boson will provide You a reasonable opportunity to cure (not less than thirty (30) days) before terminating, except for breaches of Section IV(b) or violations of applicable law, which Boson may treat as non-curable. This Agreement terminates automatically and without notice upon the events specified in Section IV(d)(iv).
155
156 Boson may, at any time, discontinue making the Higgs Materials available prospectively (including by removing them from distribution channels), but such prospective discontinuation does not, by itself, terminate the rights already granted to Licensees who are then in compliance with this Agreement.
157
158 Upon termination of this Agreement, You shall (i) immediately cease all use of the Higgs Materials and Derivative Works, (ii) delete all copies of the Higgs Materials and Derivative Works from any computer, server, or storage medium under Your control, and (iii) certify such deletion in writing to Boson upon request. Sections III, IV(a)(ii), IV(b) (with respect to any prior use, any outputs generated before termination, and the No Third-Party Rights Granted paragraph), IV(c), IV(d), IV(f), IV(g), IV(h), and IV(i) shall survive any termination or expiration of this Agreement. For clarity, termination does not require a Digital Creator to remove or take down Creator Content that was published in compliance with Section II-A before the effective date of termination, but the Digital Creator shall make no further use of the Higgs Materials after termination.
159
160 i. Governing Law and Jurisdiction.
161
162 This Agreement is governed by and construed in accordance with the laws of the State of California, without regard to its choice-of-law principles. The UN Convention on Contracts for the International Sale of Goods does not apply. The federal courts located in the Northern District of California and the state courts located in Santa Clara County, California shall have exclusive jurisdiction of any dispute arising out of or relating to this Agreement, and You consent to personal jurisdiction in those courts and waive any objection to venue.
163
164 j. Miscellaneous.
165
166 This Agreement, together with the Acceptable Use Policy and any NOTICE file accompanying the Higgs Materials, constitutes the entire agreement between the parties regarding the subject matter hereof and supersedes any prior or contemporaneous understandings. No waiver of any term shall be effective unless in writing and signed by Boson. If any provision of this Agreement is held unenforceable, the remainder shall remain in full force. You may not assign or transfer this Agreement, in whole or in part, without Boson's prior written consent; any attempted assignment in violation of this section is void. Boson may assign this Agreement freely.
