Last Updated: September 5, 2024

Please read this Chai Discovery Community License Agreement (the “License”) carefully before using the Chai-1 Model software code and model weights (the “AI Model”) and any “Outputs” (as defined below) which is offered by Chai Discovery, Inc. (“Chai”) and made available at the following link https://chaidiscovery.com/cdcla, as they may be updated and amended from time to time.

THIS LICENSE GRANTS RIGHTS ONLY TO USE THE ai MODEL, outputs, and any derivative works (AS DEFINED BELOW) SOLELY FOR NON-COMMERCIAL PURPOSES (AS DEFINED BELOW). YOU MAY NOT USE THE AI MODEL, OUTPUT, OR ANY DERIVATIVE WORKS UNDER THE TERMS OF THIS LICENSE FOR ANY COMMERCIAL PURPOSES OR AS PART OF A SERVICE OFFERING. PLEASE REVIEW SECTION “use restrictions and aup” below CAREFULLY BEFORE USING THE ai model or any output.

By downloading the AI Model, or otherwise using the AI Model or exercising any of the rights granted hereunder in any manner, You agree that You have read and agree to be bound by the terms of this License and that You will use the AI Model only for Non-Commercial Purposes (as defined below). If You are accessing the AI Model on behalf of an organization or entity, You represent and warrant that You are authorized to enter into this License on that organization’s or entity’s behalf and bind them to the terms of this License (in which case, the references to “You” and “Your” in this License, except for in this sentence, refer to that organization or entity) and that such entity is not a Commercial Entity (as defined below). No rights are granted under this License to a Commercial Entity. Use of the AI Model is expressly conditioned upon Your assent to all terms of this License.

1. Definitions.

In addition to other terms defined elsewhere in this License, the terms below have the following meanings.

  1. Commercial Entity” means any entity engaged, in whole or in part, in any activity intended for or directed toward commercial advantage or monetary compensation, including but not limited to the development of any product or service intended to be sold or made available for a fee or other economic consideration. For the purpose of this License, references to a Commercial Entity expressly exclude any universities, non-profit organizations, non-profit research institutes, and non-profit educational and government bodies.

  2. Contribution” means any work of authorship, including the original version of the AI Model and any modifications or additions to that AI Model or Derivative Works thereof, that is intentionally submitted to Chai for inclusion in the AI Model by the copyright owner or by an individual or legal entity authorized to submit on behalf of the copyright owner. For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to Chai or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, Chai for the purpose of discussing and improving the AI Model, but excluding Outputs and all communications that are conspicuously marked or otherwise designated in writing by the copyright owner as "Not a Contribution."

  3. Contributor” means Chai and any individual or legal entity on behalf of whom a Contribution has been received by Chai and subsequently incorporated within the AI Model.

  4. Derivative Work” means any work, whether in Source or Object form, that is based on (or derived from) the AI Model and for which the revisions, annotations, elaborations, or other modifications represent, as a whole, an original work of authorship. For the purposes of this License, Derivative Works shall not include works that remain separable from, or merely link (or bind by name) to the interfaces of, the AI Model and Derivative Works thereof.

  5. Non-Commercial Purposes” means uses not intended for or directed toward commercial advantage or monetary compensation, or the facilitation of development of any product or service to be sold or made available for a fee or other economic consideration. For the avoidance of doubt, the provision of Outputs or Output Derivatives as a service, or the provision of any other service that utilizes the AI Model, Derivative Works thereof, Outputs or Derivative Outputs (even if the service does not provide Outputs or Output Derivatives), is not a Non-Commercial Purpose, whether or not for a fee or other economic consideration.

  6. Object” means any form resulting from mechanical transformation or translation of a Source form, including but not limited to compiled object code, generated documentation, and conversions to other media types.

  7. Output” means any output that is made available to You by the functionality of the AI Model, including but not limited to any protein sequence, structure prediction, functional annotation, molecule, descriptions of a molecule, structure predictions, confidence rankings, intermediate model states, model, model embeddings, sequence, text, and/or images. 

  8. Output Derivatives” means any enhancements, modifications and derivative works of Outputs (including, but not limited to, any derivative sequences, structures, or molecules).

  1. Copyright License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a limited, non-exclusive, worldwide, royalty-free, non-transferable, non-sublicensable copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform, and distribute the AI Model and such Derivative Works in Source or Object form solely for Your Non-Commercial Purposes and subject to the restrictions set forth in Sections 3 (“Use Restrictions and AUP”) and 4 (“Sharing and Distribution”).

  2. Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a limited, non-exclusive, worldwide, royalty-free, non-transferable, non-sublicensable patent license to make, have made, use, import, and otherwise transfer the AI Model solely for Your Non-Commercial Purposes and subject to the restrictions set forth in Sections 3 (“Use Restrictions and AUP”) and 4 (“Sharing and Distribution”), where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by its Contribution(s) alone or by combination of its Contribution(s) with the AI Model to which such Contribution(s) was submitted.

    1. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the AI Model or a Contribution incorporated within the AI Model constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that AI Model shall terminate as of the date such litigation is filed and may be reinstituted only by a separate grant of a patent license in writing from the Contributor.

3. Use Restrictions and AUP.
  1. No Commercial Use.  You may use the AI Model, Contributions, Derivative Works, Outputs and Output Derivatives only for Non-Commercial Purposes.

The contents of such Attribution Notices are for informational purposes only and do not modify this License. You may add Your own attribution notices within Derivative Works or Output Derivatives that You distribute, alongside or as an addendum to the pertinent Attribution Notices, provided that such additional attribution notices cannot be construed as modifying this License.
