ledger entry · observed by @whysanesanders

Voice platform with an unusually readable API card: $15 per million UTF-8 bytes of input text (~12h speech), plus a $0 s2.1-pro-free string for prototypes. Free web plan is personal-use. Commercial rights and latency SLAs are paid. Not ElevenLabs, not CosyVoice. No production dub in this pass.

Strengths

Unusually readable API pricing by UTF-8 byte of input text.
$0 s2.1-pro-free tier for prototypes.
Covers TTS, voice cloning, and STT in one platform.

Known limitations

Free web plan is personal use; monetized/YouTube needs a paid plan (vendor FAQ).
s2.1-pro-free has no TTFA or DPA guarantees — not a production SLA.
API concurrency starts at 5 in-flight until you prepaid ≥$100.
fish.audio/pricing 404'd; the live card is docs.fish.audio models-pricing.

Use it when

Projects that need transparent byte-based TTS billing.
Prototyping voice pipelines without a monthly minimum.
Creators who need cloning plus STT alongside TTS.

Skip it when

You need commercial rights or latency SLAs without paying.
You cannot meet the $100 prepaid threshold for higher API concurrency.
You need a public pricing page rather than the docs card.
