作者： Jakub Rusinowski · 最后更新： 2026年7月12日
Yes. Qwen3-Coder 480B-A35B (MoE) needs 291.6 GB at 8K context (289.8 GB weights + 1.8 GB KV cache/overhead) at Q4_K_M and the Apple M3 Ultra has 384 GB usable, leaving about 92.4 GB of headroom, at roughly 20 tok/s (estimated) with room for up to 256K of context.

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.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
No compatible GPU? Qwen3-Coder on 16 GB of system RAM, CPU only: runs, but it is tight.
