Thanks for the report. It looks like the model files were only partially downloaded into the cache directory (~/.cache/gigaam). We’ll add checksum verification to handle this in the next release.

In the meantime, please clear the cache directory so the checkpoints can download again and then rerun your script. After that, the model should load cleanly. If the issue persists, let us know.

We’ve just added checksum validation for model downloads. If the downloaded checkpoint is corrupted, you’ll now get a clear error message asking you to remove the local model folder and download it again.

Please update to the latest version.
