Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 51.5 GB, but this setup only exposes 25.9 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, DeepSeek LLM 67B requires more memory than MacBook Pro M4 Max 36GB provides.
DeepSeek LLM 67B (67B parameters) requires approximately 51.5 GB of memory with Q4_K_M quantization.
The recommended quantization for DeepSeek LLM 67B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Max 36GB, DeepSeek LLM 67B achieves approximately 5.7 tokens per second decode speed with a time-to-first-token of 33762ms using Q4_K_M quantization.
For coding workloads, DeepSeek LLM 67B on MacBook Pro M4 Max 36GB receives a F grade with 5.7 tok/s and 4K context.
On MacBook Pro M4 Max 36GB, DeepSeek LLM 67B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.

Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Not always. MacBook Pro M4 Max 36GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
