Veizik for Apple Silicon — 2026.09.21
The first publicly downloadable Veizik build for Apple Silicon: signed, notarised, and published with its SHA-256.
This page records the state as of 2026-09-21 and is not updated as the catalogue moves. For what runs now, see models.
What this build does
- Published as a signed, notarised disk image with its SHA-256 beside it, so the download can be checked before it is opened.
- A mismatched checkpoint is refused. Pointing a core at another model's weights now stops with an error instead of running with the wrong geometry.
- Commands take the catalogue identifier a listing prints, and the short size tag still works as an alias.

Fixed issues
- An earlier build accepted a checkpoint whose shape did not match the core and ran to completion on it; the shape is checked before the weights are read.
- The packaged instructions named a file the package does not contain.
Known issues in 2026.09.21
- Greedy decoding only. Temperature, top-p, and top-k are not implemented in this build.
- Output quality is not tuned in this build. Compare outputs with the published test prompts before quality-sensitive deployment.
- Base checkpoints only for the supported models. Other architectures are refused rather than attempted.
- veizik convert reports whether a checkpoint is supported; it writes no converted file, and none is needed to run one.
