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 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 Q4_K_M on the NVIDIA GeForce RTX 4070 Ti: 8K 10.8 GB · 16K 11.5 GB. Every window this model publishes still fits 12 GB.
No compatible GPU? StarCoder 2 15B on 16 GB of system RAM, CPU only: runs, but it is tight.
