voicecast-worker

VoiceCast Worker lends your Mac to VoiceCast Studio. It pulls bite-size jobs from the studio's one job queue, does them on your GPU, and hands the results back:

• pictures: FLUX.2 klein on Apple silicon with mflux, the model kept loaded (an M2 Ultra draws a picture in about 6 s, an M2 Max in about 20 s);
• narration: one paragraph at a time with sonic-forge (Kokoro, and cloned voices on the Apple GPU), assembled by the studio with the same seeded pauses as a whole narration;
• picture checks and whole renders: only on machines the studio owner trusts (renders need a checkout of the studio app).

Your own Mac makes your own videos first: the worker alternates one job for someone else, one of yours ("give one, take one"). It never opens a port: it calls the studio over HTTPS, and files travel by short-lived presigned URLs.

Install

pipx install 'voicecast-worker[pictures,voice,menubar]'
voicecast-worker join <join-token> --server https://voicecast.studio

Get the join token from the studio's Developers page ("Join a Mac"), or with voicecast worker join. Then run it in a terminal (voicecast-worker run) or from the menu bar (voicecast-worker menubar: Pause/Resume, Start at login).

Extras: pictures (mflux), voice (sonic-forge + Kokoro), clone (sonic-forge cloned voices on the Apple GPU), menubar (rumps), all.

When it works

voicecast-worker settings --gpu-max 35        # only while the GPU is quiet (someone else's model, a game)
voicecast-worker settings --user-idle 300     # only when you've been away 5 minutes
voicecast-worker settings --gpu-share 0.5     # rest as long as it worked
voicecast-worker settings --hours "22:00-08:00"
voicecast-worker pause / resume
voicecast-worker status
voicecast-worker doctor                       # which engines this Mac can run
voicecast-worker leave

State lives in ~/.voicecast/worker/ (an older ~/.video-maker-worker/ is still read) (config.json with the machine token, status.json, worker.log).

Privacy

What a machine may see depends on its trust, set by the join token: a person's own Mac (self) only takes their own jobs; a community Mac only takes public, bite-size jobs, never a cloned voice's reference, a real person's portrait, a presenter's take or a whole render. Work on a Mac is not encrypted while it runs there; that is why private and personal work only goes to machines that may see it.
