Settings and model questionsCheck the available settings and guidance when preparing your input.
Inputs and settings
Text mode takes prompt and duration from 1 to 120 seconds. Audio-to-audio also takes an uploaded audio_url and init_noise_level.
Inpainting replaces only mask_start_seconds to mask_end_seconds; the end must follow the start and stay within the uploaded source.
Outpainting needs a positive extend_seconds_before or extend_seconds_after. Raywake checks that the source and extensions fit within 120 seconds.
Choose MP3, WAV, FLAC, OGG, Opus, M4A or AAC. Bitrate applies to compressed formats; base checkpoints expose guidance and more sampling steps.

From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
