FAQ
Can Apple M5 Max (128GB) run DeepSeek-V2-Lite?
Yes. DeepSeek-V2-Lite runs on Apple M5 Max (128GB) at Q4_K_M (~12.2 GB of ~96 GB usable).
How much memory does DeepSeek-V2-Lite need?
Apple M5 Max (128GB) has room to spare. At Q4_K_M the weights are ~10.4 GB; with KV cache and runtime overhead, budget ~12.2 GB at a 4k context. It is a Mixture-of-Experts model (16B total / 2.4B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run DeepSeek-V2-Lite on macOS?
LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.
