Input

Field	Kind	Default	Description
`prompt`	text	—	The text prompt describing the music to generate
`composition_plan`	JSON	—	The chunk-based composition plan for the music
`music_length_ms`	number (whole) 3000 to 600000	—	The length of the song to generate in milliseconds. Used only in conjunction with prompt. Must be between 3000ms and 600000ms. Optional - if not provided, the model will choose a length based on the prompt.
`force_instrumental`	true or false	false	If true, guarantees that the generated song will be instrumental. If false, the song may or may not be instrumental depending on the prompt. Can only be used with prompt.
`seed`	number (whole)	—	Random seed to initialize the music generation process. Can only be used with composition_plan. The same seed with the same parameters gives more consistent results, but exact reproducibility is not guaranteed.
`output_format`	one of mp3_22050_32, mp3_24000_48, mp3_44100_32, mp3_44100_64, mp3_44100_96, mp3_44100_128, mp3_44100_192, mp3_48000_128, mp3_48000_192, mp3_48000_240, mp3_48000_320, pcm_8000, pcm_16000, pcm_22050, pcm_24000, pcm_32000, pcm_44100, pcm_48000, ulaw_8000, alaw_8000, opus_48000_32, opus_48000_64, opus_48000_96, opus_48000_128, opus_48000_192	mp3_48000_192	Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. Note that the μ-law format (sometimes written mu-law, often approximated as u-law) is commonly used for Twilio audio inputs.
