Ternary Bonsai 2 27B on the Apple M4: VRAM by quantization
| Quant | VRAM needed | Fits 32 GB? | Max context | Whole PC |
|---|---|---|---|---|
| PQ2_0 ternary | 8.5 GB | ✓ Yes | 128K | — |
| PTQ1_0 ternary | 7.3 GB | ✓ Yes | 256K | — |
Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 32 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At PTQ1_0 ternary on the Apple M4: 8K 7.3 GB · 32K 8.9 GB · 128K 15.3 GB. Every window this model publishes still fits 32 GB.
