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 512 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 Ultra: 8K 291.6 GB · 32K 294.8 GB · 128K 307.2 GB. Every window this model publishes still fits 512 GB.
No compatible GPU? Qwen3-Coder on 16 GB of system RAM, CPU only: runs, but it is tight.
