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 128 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 Q4_K_M on the Apple M3 Max: 8K 45.7 GB · 32K 53.8 GB · 128K 86 GB. Every window this model publishes still fits 128 GB.
No compatible GPU? Cogito v1 on 8 GB of system RAM, CPU only: runs.
