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 12 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 BF16 on the Intel Arc B580: 8K 9.7 GB · 16K 10.6 GB. Every window this model publishes still fits 12 GB.
No compatible GPU? Cosmos 3 Edge on 8 GB of system RAM, CPU only: runs, but it is tight.
