よくある質問
Send POST /api/v1/chat/completions with modalities set to ["text", "audio"] and an audio object naming the voice and format. Audio output requires stream: true; the response arrives as SSE chunks, and the client concatenates the base64 delta.audio.data fragments in order before decoding the combined string once into the final file. The audio guide covers the request and the chunk format. For dedicated speech synthesis, use the text-to-speech models at POST /api/v1/audio/speech.
Listings with published pricing show input audio and output audio prices per million tokens next to their text token prices, so the cost of a reply depends on how much audio it returns. You pay only for the requests you make, with no separate subscription per provider.
Set audio.voice and audio.format in the request. Voices such as alloy or nova and formats such as wav, mp3, flac, opus, and pcm16 vary by model, so check the model page before you choose.
