from openai import OpenAI

client = OpenAI(
    api_key=os.environ.get("MIMO_API_KEY"),
    base_url="https://api.xiaomimimo.com/v1"
)

# Clip voice style
text = "<style>夹子音</style>主人～我来啦！今天有什么需要帮忙的吗～"

completion = client.chat.completions.create(
    model="mimo-v2-tts",
    messages=[
        {"role": "user", "content": "你好"},
        {"role": "assistant", "content": text}
    ],
    audio={"format": "wav", "voice": "default_zh"}
)

audio_bytes = base64.b64decode(completion.choices[0].message.audio.data)
with open("output.wav", "wb") as f:
    f.write(audio_bytes)

Notes

• Target text must be in the assistant role message, not in user
• <style> tag must be at the beginning of target text
• For singing: <style>唱歌</style>target text
• Returns base64-encoded WAV audio
