OpenAI gpt-4o-mini-tts Model Terms

Version: 2026-10 (Last updated: October 10, 2026)

These Model Terms form part of the Speech Synthesis Model Terms and apply to users who configure "OpenAI gpt-4o-mini-tts" for a show on Lisnify.

1. Model and upstream terms

The Company is not affiliated with OpenAI, and OpenAI does not provide, warrant, or endorse the Service.

2. Summary

OpenAI speech synthesis is subject to the OpenAI Usage Policies. It must not be used for unlawful activities, harming or harassing others, impersonation, fraud or spreading misinformation, or infringing the rights of others. OpenAI requires that listeners be clearly told that synthesized speech is AI-generated and not a human voice; Lisnify automatically states in the show description that the script and audio are generated by AI. No consent is requested when configuring a show, but you must comply with these Model Terms.

3. User obligations

In a show configured with OpenAI gpt-4o-mini-tts, you must not use the Service for any purpose prohibited by the OpenAI Usage Policies. In outline, the policies prohibit the following (the wording of the policies themselves governs):

1. Violating the law or the rights of others (including privacy and intellectual property)
2. Harming, exploiting, or harassing others, promoting self-harm or violence, child sexual exploitation
3. Impersonating others without consent, fraud, creating or spreading misleading information or disinformation (including hiding that content is AI-generated so that it appears to be made by a human)
4. Undermining democratic processes, such as political campaigning or lobbying, or misinformation about elections
5. Providing medical, legal, financial, or other professional advice without the involvement of a qualified professional

Disclosure of AI-generated speech: OpenAI requires that, when text-to-speech output is provided to end users, they are clearly informed that the voice is AI-generated and not a human voice. The Company automatically states in the show description that the script and audio are generated by AI (Model Terms, Section 3, Item 1). You must not remove this statement when providing generated content to third parties.

4. What the Company does

• OpenAI gpt-4o-mini-tts imposes no separate consent obligation on downstream users, so the show settings screen only shows a link to these Model Terms.
• Changes to these Model Terms follow the procedure in Section 4 of the Model Terms.
