This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Yes, Mac Studio M1 Ultra 64GB can run LLaVA 1.6 13B with a A grade (Runs well). Expected decode speed: 55.5 tok/s.
LLaVA 1.6 13B (13B parameters) requires approximately 27.9 GB of memory with Q4_K_M quantization.
The recommended quantization for LLaVA 1.6 13B is Q4_K_M, which balances quality and memory efficiency.
On Mac Studio M1 Ultra 64GB, LLaVA 1.6 13B achieves approximately 55.5 tokens per second decode speed with a time-to-first-token of 3489ms using Q4_K_M quantization.
For coding workloads, LLaVA 1.6 13B on Mac Studio M1 Ultra 64GB receives a A grade with 55.5 tok/s and 4K context.
On Mac Studio M1 Ultra 64GB, LLaVA 1.6 13B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.
Not always. Mac Studio M1 Ultra 64GB 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.
