Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| firered_model | FIREREDTTS3_MODEL | — | |
| audio | AUDIO | Input speech to edit. | |
| instruction | STRING | Replace 'cats' with 'dogs'. | Content edit instruction: insertion, deletion or substitution, e.g. "insert 'really' after the word at index 8." |
| n_timesteps | INT | 101–50 | Flow-matching steps per generated audio patch. 10 is the official default; more is slower with diminishing returns. |
| inference_cfg | FLOAT | 1.200–4 | Classifier-free guidance strength for the flow head. 0 disables CFG. Official defaults: 2.0 for cloning, 1.2 for design/edits. |
| stop_threshold | FLOAT | 0.500.05–0.95 | Stop-token probability threshold that ends generation. Higher values allow longer audio. |
| seed | INT | 420–2147483647 | 0 uses the current random state. A positive value is repeatable. |
| max_audio_seconds | FLOAT | 644–160 | Hard cap on generated audio length per sentence (64s is the official maximum). |
