Appliance Releases

Version history for the Fish Audio enterprise appliance

Every version of the enterprise appliance we have released, newest first. Developer → Self Host shows which one your team recorded as running and links here when a newer one is available.

Versions are immutable. A tag always refers to the same image — we never re-point one at different content, so a deployment pinned to a tag keeps getting the bytes it was tested with. Fixes ship as a new version.

First generally available build of the appliance.

• Serves the S2.1 Pro voice model, weights baked in — no network access at runtime.
• Two GPUs: language model on GPU 0, vocoder on GPU 1.
• Usage recorded to a local signed ledger; nothing is reported off the host.
• Runs fully non-root (UID 1000).

Upgrading: nothing to migrate — this is the first release.

Getting an older version

The dashboard lists the versions we currently recommend. If you need one that is no longer listed — to reproduce a node exactly as it was, for instance — contact your account manager rather than guessing a tag.
