textSTRINGHello! This is Higgs Audio v3 running natively inside ComfyUI.Text to synthesize. Inline tags work anywhere, for example <|emotion:relief|>, <|prosody:pause|>, or <|sfx:laughter|>Haha at the exact moment it should happen.
max_new_tokensINT204832–8192Maximum audio-code tokens per single pass. 2048 is roughly 25-30 seconds; raise it or enable chunking if speech cuts off.
temperatureFLOAT1.000–2Sampling variety. 0 is greedy and repeatable; around 0.8-1.1 is usually natural.
top_pFLOAT0.950–1Nucleus sampling cutoff. 1.0 disables it; 0.9-0.98 keeps speech expressive without wandering too much.
top_kINT500–1026Limits each codebook sample to the top K choices. 0 disables; 50 is a steady default.
seedINT00–21474836470 uses the current random state. A positive value is repeatable and is reused unchanged for every longform chunk.
longform_chunkingBOOLEANtrueSplit long text at sentence or pause-tag boundaries. Turn this on for narration; off is one direct pass and may stop early on long text.
words_per_chunkINT4520–300Target words per chunk. Around 35-55 fits the 2048-token default better; raise with max_new_tokens for longer chunks.
pause_between_chunksFLOAT0.150–2Seconds of silence inserted between longform chunks. Does not replace inline pause tags.
