1-bit (binary, ~1.125 bpw)6.3 GB✓ Yes8K—

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 8 GB. 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 1-bit (binary, ~1.125 bpw) on the AMD Radeon RX 9060 XT 8GB: 8K 6.3 GB · 32K 11.6 GB ✗ · 128K 32.5 GB ✗. Past 32K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.

No compatible GPU? 1-bit Bonsai 27B on 16 GB of system RAM, CPU only: runs comfortably.
