TTS-1

The catalogued TTS-1 is presented as OpenAI's text-to-speech model, routed through the Vercel AI Gateway under the model key openai/tts-1. Its role within the catalog is narrow and practical: converting written input into spoken output for applications that need synthesized voice, rather than serving as a general-purpose language model. Because it appears behind a gateway rather than via an OpenAI-native endpoint, its availability and behavior depend on the gateway's implementation of the underlying OpenAI TTS capabilities.

Among the supplied sources, only third-party integration documentation acknowledges an OpenAI TTS option by listing it as one of several voice providers in a comparison matrix, which situates TTS-1 within a broader ecosystem of voice synthesis services that includes both platform-native and third-party providers. The other supplied source describes a separately named "TTS-1" from a different creator and is not applicable to the catalogued model's technical characteristics. As a result, the overview of this OpenAI TTS-1 entry remains limited to what the catalog attributes establish, with no verified claims about architecture, training scale, supported languages, audio formats, or benchmark performance from the supplied evidence.
