Veizik for Apple Silicon — 2026.09.23

The 2026.09.21 code, re-sealed and re-published to correct five errors in the shipped documentation. The compute path is unchanged; the release states so and measures it rather than asserting it.

This page records the state as of 2026-09-23 and is not updated as the catalogue moves. For what runs now, see models.

What this build does

• Republished so the documentation could be corrected: an already-published release cannot be edited in place without republishing it.
• The speed difference against the previous build was measured rather than argued: 7B decode, nine rounds, arms interleaved and the order rotated every round, median difference +0.066% against a noise floor written down before the runs.
• The core code sections are not byte-identical to the previous build and the release says so, giving both the file hash and the __TEXT,__text digest for each core.

Models in this release

Install size

3.1 MB, 10 files — no dependency to install first

Verification

SHA-256 checksum list included with the package

Verify, install, check

$ ./install.sh
$ veizik doctor

Full steps are in the documentation.

Fixed issues

• Two things that should not have been in a published document were removed from the benchmark discussion: an internal implementation parameter, and a stage-by-stage cost breakdown.
• __text byte counts had been left at the previous build while the hashes beside them were refreshed, so a reader following the document's own verification step would have been stopped by a stale column.
• A file count said fifteen where the package holds sixteen, of which the checksum manifest covers the other fifteen.
• Two adjacent paragraphs stated the same fact in opposite directions.
• The security notes were narrowed to checks a reader can actually run.

Known issues in 2026.09.23

• 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.
