Keep the OpenAI SDK. Point it at AllModels, then replace the model and voice. Your speech-generation call stays the same.
https://api.allmodels.io/oai.elevenlabs/eleven-v3 and choose an ElevenLabs voice ID.AllModels is an independent service and is not affiliated with, endorsed by, or sponsored by OpenAI, ElevenLabs, Fish Audio, or Cartesia.
These examples generate a normal MP3 response. Highlighted lines are the only provider-migration changes.

The AllModels-compatible OpenAI SDK surface supports text-to-speech and streamed speech responses, file transcription, and realtime transcription. Read the complete OpenAI SDK compatibility guide for setup details, supported methods, and current limitations.
Eleven v3 is ElevenLabs’ generally available, most advanced text-to-speech model. ElevenLabs says the production release is more stable and more accurate than the earlier alpha, especially when reading numbers, symbols, and specialized notation across languages.
In its internal benchmark across 27 categories and eight languages, ElevenLabs reports a 68% reduction in errors. That makes v3 particularly relevant for scripts containing phone numbers, currencies, formulas, scores, URLs, and other context-sensitive text.
Quick answers
No. Keep the installed SDK and its speech method. AllModels exposes a compatible base URL for it.
No. Choose a voice from the Eleven v3 voice list, then replace ELEVENLABS_VOICE_ID with its ID.
Yes. Keep the AllModels base URL and API key, then change the model and voice to another supported provider.
