Quickstart
1. Register for an account
First, register for an account to get an API key. New accounts come with $5 to get started. Once you’ve registered, set your account’s API key to an environment variable namedTOGETHER_API_KEY:
export TOGETHER_API_KEY=xxxxx
2. Query the models via our API
In this example, we’re giving it a string and asking the model to return a.mp3 back to us.
from together import Together
client = Together()
speech_file_path = "speech.mp3"
response = client.audio.speech.create(
model="cartesia/sonic",
input="Today is a wonderful day to build something people love!",
voice="helpful woman",
)
response.stream_to_file(speech_file_path)
import Together from 'together-ai';
const together = new Together();
async function generateAudio() {
const res = await together.audio.create({
input: 'Hello, how are you today?',
voice: 'laidback woman',
response_format: 'mp3',
sample_rate: 44100,
stream: false,
model: 'cartesia/sonic',
});
if (res.body) {
console.log(res.body);
const nodeStream = Readable.from(res.body as ReadableStream);
const fileStream = createWriteStream('./speech.mp3');
nodeStream.pipe(fileStream);
}
}
generateAudio();
curl --location 'https://api.together.ai/v1/audio/generations' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer $TOGETHER_API_KEY' \
--output speech.mp3 \
--data '{
"input": "hello, how are you?",
"voice": "laidback woman",
"response_format": "mp3",
"sample_rate": 44100,
"stream": false,
"model": "cartesia/sonic"
}'
speech.mp3file that can be played.

Output Raw Bytes
If you want to extract out raw audio bytes use the settings below:import requests
url = "https://api.together.ai/v1/audio/generations"
headers = {"Authorization": f"Bearer {TOGETHER_API_KEY}"}
data = {
"input": text,
"voice": voice,
"response_format": "raw",
"response_encoding": "pcm_f32le",
"sample_rate": 44100,
"stream": False,
"model": "cartesia/sonic",
}
response = requests.post(url, headers=headers, json=data)
with open("text2.pcm", "wb") as f:
f.write(response.content)
import Together from 'together-ai';
const together = new Together();
async function generateRawBytes() {
const res = await together.audio.create({
input: 'Hello, how are you today?',
voice: 'laidback woman',
response_format: 'raw',
response_encoding: 'pcm_f32le',
sample_rate: 44100,
stream: false,
model: 'cartesia/sonic',
});
console.log(res.body);
}
generateRawBytes();
curl --location 'https://api.together.ai/v1/audio/generations' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer $TOGETHER_API_KEY' \
--output test2.pcm \
--data '{
