Highlights
- GGUF Q8_0 conversion of the merged BF16 checkpoint, with a native S1 decision runtime and separately fitted GGUF temperature.
- BoolQ specialist: one epoch of rank-8 LoRA on 2,048 English examples, merged into the full multimodal model; not full-parameter training.
- Two files: s1-boolq-Q8_0.gguf at 12,669,647,264 bytes and mmproj-s1-boolq-f16.gguf at 122,031,744 bytes, 12,791,679,008 bytes total.
- Twelve native execution checks passed on Apple M1 Max, 64 GiB, covering text, image, audio and an 8,481-token request crossing the batch boundary.
- Choice, Noul and Score are supported schemas, but training establishes evidence only for passage-grounded English yes/no decisions.
Watch out
Card reviewed 2026-10-17; the twelve native execution checks and the 8 requests with 29 typed answers are functional smoke tests, not accuracy or calibration measurements, and the card says matching tokens and positions does not imply numerical parity with BF16 or MLX. The runtime targets Apple Silicon/macOS and needs the custom native S1 runner, since a generic chat-generation command does not implement this decision interface. The fetched card text ends before the full build steps, so no run command is quoted here.
