Now you can grow Bonsai on your potato
Full 27B-class reasoning in ternary transformer weights, for llama.cpp (CUDA, Metal, CPU)

Proof1 community thread
Key points
- No more excuses for GPU-poor folks not to start LLMing!
- ~9.3x smaller than FP16 (ideal) | 98.2% of FP16 intelligence retained | ~47 tok/s on an Apple M5 Max laptop
- ~5.9 GB language model (down from ~54 GB FP16) — full 27B-class reasoning on a standard laptop or a single GPU
- Two GGUF packings with custom ternary hybrid-attention kernels for llama.cpp (CUDA, Metal) — PTQ10 packs trits densely (1.75 bits/weight, 5.95 GB), PQ20 stores each trit in a 2-bit slot (2.13 bits/weight, 7.21 GB); packed weights are consumed directly, never expanded back to FP16
