Ternary Bonsai 2 27B on the Apple M4: VRAM by quantization

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.
