Produce speech and clone voices with Fish Audio — its hosted TTS API (S2.1-Pro / S2-Pro / S1 model lineup, REST + WebSocket streaming, instant and persistent voice cloning) and its open-weight OpenAudio S1-mini / Fish-Speech models for self-hosting. Use this skill when an agent must generate narration or dialogue through Fish Audio, choose between Fish Audio's hosted models and open weights, clone a voice from reference audio, author emotion/tone/special markers for expressive delivery, estimate cost from UTF-8 bytes, wire real-time streaming for a voice agent, decide whether self-hosting beats the API, or review Fish Audio TTS output for production. Do not use it to pick a different provider — it covers Fish Audio specifically.

# Fish Audio text-to-speech and voice cloning
Fish Audio is a TTS and voice-cloning provider with two distinct product surfaces that share a lineage but differ in licensing and operation:
1. **Hosted API** (`api.fish.audio`) — the commercial service. Current lineup is branded **S2.1-Pro / S2-Pro / S1**. Paid per UTF-8 byte, streaming, cloning, and a free tier.
2. **Open weights** — released under the **OpenAudio** brand (and earlier as **Fish-Speech**). Downloadable from Hugging Face and GitHub for self-hosting.
The single most important fact to get right: **the hosted API and the open weights are not the same models, and their licenses differ**. The full flagship weights are hosted-only; only smaller distilled weights are openly published, and those carry a **non-commercial** license. Never assume "Fish is open source, so I can self-host it commercially" — verify which artifact and which license apply. See *Open weights and self-hosting* below.
All model names, prices, endpoints, and limits below are volatile. **Verification date for every dated claim in this document: 2026-07-10.** Re-verify against `docs.fish.audio` before quoting these to a user as current.
Labels used throughout:
- **[Doc]** — stated in official Fish Audio / OpenAudio documentation, model cards, or their published technical reports.
- **[Claim]** — a first-party marketing or benchmark claim from Fish Audio/OpenAudio; treat as their assertion, not independently established.
