Veizik for Apple Silicon — 2026.10.02-r6.2

Sampling options on `veizik run`. The engines are byte-for-byte the r6.1 engines; only the `veizik` command changed, and sampling uses the sampler the engines already contained.

This page records the state as of 2026-10-09 and is not updated as the catalogue moves. For what runs now, see models.

Verification
The file name, size and SHA-256 are printed on this page and on the release page, and the two agree. The disk image is signed with a Developer ID and notarised, and carries SHA256SUMS covering its other 49 files, so `shasum -a 256 -c SHA256SUMS` checks the contents after you open it.

Fixed

Fixed issues

  • veizik run takes --temperature T (above 0 turns sampling on), --top-k K (default 40 when sampling), --top-p P (default 1.0) and --seed N. The same seed and settings repeat the same text on the same Mac; without a seed, or with --seed 0, every run draws a new one. Values must be plain numbers; anything else is refused before the engine starts.
  • Without these options veizik run is unchanged: greedy decoding, the same output as r6.1 for the same prompt. veizik chat and veizik bench stay greedy; veizik serve already passed request sampler fields to the engine.
Known issues

Known issues in 2026.10.02-r6.2

  • /v1/embeddings answers 501 in this release.
  • The serve window is 4,096 tokens per request for every model in this release (prompt plus max_tokens); veizik run is not limited this way.
  • Qwen3-1.7B returns its reasoning text inside the answer; add /no_think to the prompt for a direct reply.
  • Offline use: the session key lasts 48 hours after an online start; restarting the Mac ends that window.
  • Not supported: Intel Macs, Windows, Linux. Headless activation is not included in this build.
