h3 studio
video + audioNative Metal video and audio generation from MiniMax-H3, no PyTorch in the loop.
native-kernelmetalmacOSApple Siliconpeak ~21 GB
Open-weight video, image and speech models on your own machine, without the afternoon of setup.
helmstudio installs, runs and switches between studios — each one a repository that wraps an open model — and keeps what every studio makes in one gallery, with where it came from.
There is no release yet, so helmstudio runs from a source build.
The afternoon of setup, made concrete
The submodule you did not clone
A manifest names the repository, the commit and whether it has submodules, and install clones all of it at that commit, then runs the build steps the manifest lists.
The Python version mismatch
A studio declares the Python it needs, and helmstudio gives it an environment of its own, made with uv, so two studios never share one.
The 60 GB download with no resume
Weights come from Hugging Face a file at a time, and a download resumes where it stopped. Studios that name the same repository at the same revision share one copy, and a folder you already have can be linked instead.
Two studios that both want port 8720
A port in a manifest is a preference: when something else has it, the process is given a free one. And one studio holds a model in memory at a time, so launching a second says what it would stop, and asks.
The launch studios
What each one needs, read from its manifest.

What runs where
- The launch studios are built for macOS on Apple Silicon: Metal, MPS and MLX.
- helmstudio's Go code is type-checked for Linux on every gate run. Nothing has been run there: not the daemon, and not a studio.
- Windows is not supported.
Add your own studio
Most repositories worth running will never ship a manifest, so writing one for a repository you did not write is a first-class act, not a workaround.
