tts-1-hd is a speech synthesis model from OpenAI. You provide text, and receive a ready-made voiceover with a focus on sound quality. It is suitable for audio versions of articles, podcasts, videos, and training courses, as well as voice responses in bots and applications. In BotHub, the model is available from Russia and can be paid for in rubles.

You receive an audio track as output: the 'hd' prefix in the name indicates a version focused on sound quality. The file format is set by the request parameter, defaulting to MP3. The text volume per call is limited to a context of 4095 tokens; it is more convenient to split long materials into parts.

In our data, a reasoning mode for tts-1-hd is not noted, and given its task, the model does not assume it: it does not conduct dialogue or solve problems, but voices ready-made text. The logic and wording are prepared by the model or script that writes the text before voicing.

Function calling and structured output are not noted in our data — these are tools for text models, while tts-1-hd is responsible for voiceover. If your scenario requires both functions and voice, link them via the unified OpenAI-compatible BotHub API: the text model prepares the response, and tts-1-hd voices it.

Accepting files other than text is not noted in our data: you provide text as input to tts-1-hd and receive audio as output. If you need to recognize speech from a recording or analyze an image, select a specialized model in the same BotHub window — switching does not require rewriting the integration.

We do not provide data on language support for tts-1-hd, so we will not make specific promises — it is more reliable to test with your own text. In BotHub, payment is based on actual tokens used, so a short test will be inexpensive, and access works from Russia without a VPN or foreign card.
