4. AI/ML Content

4.1 Processing of AI/ML Content.  Customer agrees it has the right to provide the AI/ML Content to Twilio and its affiliates for processing in accordance with this Addendum.

(a) Customer Instructions.  Customer and Twilio agree that, in accordance with Customer’s instructions, Twilio and its affiliates will process AI/ML Content (i) as set forth in the Agreement and this Addendum; (ii) as necessary to make available and improve the performance, functionality, safety, and security of the AI/ML Features, which includes, without limitation, development and model training to detect, investigate, and prevent security incidents, network exploits and abuse, spam, and violations of our Twilio Acceptable Use Policy; (iii) as necessary to comply with applicable law or regulation; and (iv) to improve, train, or fine-tune the AI/ML Features solely for Customer’s benefit in connection with Customer’s use of such AI/ML Features.

4.2 Output.  AI/ML Features use emerging technology that may provide Output that is inaccurate, is offensive, poses a threat to public safety, or is not designed or intended to meet Customer’s needs, expectations, or legal, regulatory, or compliance obligations. Customer is solely responsible for reviewing, editing, and amending any Output before publishing, using, or relying on such Output. Due to the nature of artificial intelligence or machine learning technology, Output may not be unique, and any AI/ML Feature may generate the same or similar Output for other customers. Twilio does not guarantee the generation of Output by any AI/ML Feature.

5. Third-Party AI/ML Technology.  Twilio may use artificial intelligence or machine learning technology provided by a third party (“Third-Party Technology”) to provide some or all of the functionality for the AI/ML Features. By using the AI/ML Features, Customer acknowledges and permits Twilio and its affiliates to disclose any Input, as determined by Twilio, in its sole discretion, with the applicable Third-Party Technology provider; provided, however, no Input will be disclosed to a Third-Party Technology provider for the purpose of training or fine-tuning its underlying base model, without Customer’s acceptance of or agreement to supplemental terms granting Twilio the right to do so. AI/ML Features that use any Third-Party Technology are identified in Exhibit A attached hereto. Customer will comply with the applicable Third-Party Technology provider’s acceptable use terms identified in Exhibit A attached hereto. Twilio is not an agent or partner or in a joint venture with any Third-Party Technology provider.

6. Consents and Right to Review.  Some AI/ML Features may provide automatic speech recognition technology, speech-to-text or text-to-speech capabilities, or natural language understanding and involve the monitoring or capture of real-time transcription of End User communications by Twilio that requires informed consent from End Users in accordance with applicable law or regulation (“Consents”). Customer will obtain Consents prior to an End User’s use of, or interaction with, the AI/ML Features, and maintain appropriate records of all Consents it has obtained. Customer will promptly provide evidence of all Consents to Twilio for review upon Twilio’s written request.

7. Ownership.  As between the parties, (a) Twilio exclusively owns, or its Third-Party Technology providers exclusively own, as applicable, all right, title, and interest in and to the AI/ML Features and (b) Customer exclusively owns all right, title, and interest in and to AI/ML Content that is unique solely to Customer.

8. Conflict.  In the event of any conflict or inconsistency among the following documents, the order of precedence will be as follows with respect to the use of any AI/ML Feature: (1) the Business Associate Addendum (if applicable and only with respect to protected health information that is protected and regulated under the Health Insurance Portability and Accountability Act of 1996, as amended from time to time), (2) this Addendum, and (3) the Agreement.
