}Frequently asked questions
Running locally
Qwen3.5 35B-A3B Base needs an estimated 24.9 GB of VRAM at Q4, 43.3 GB at Q8 or 81 GB at FP16. These figures are estimates from the 35B parameter count, covering weights plus about 15% and 0.5 GB for a short context.
No. A 24 GB, 16 GB, 12 GB or 8 GB GPU does not fit Qwen3.5 35B-A3B Base at Q4, Q8 or FP16, based on estimates.
Yes, with enough unified memory. Q4 needs an estimated 24.9 GB, and assuming macOS lets the GPU use about 75% of unified memory, the smallest common Mac memory size that fits Q4 is 36 GB (estimate).
Privacy and data
Yes. Qwen3.5 35B-A3B Base has open weights, so you can self-host it for full control of your data.
