Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 186.3 GB, but this setup only exposes 92.2 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, K EXAONE 236B A23B requires more memory than Mac Studio M2 Ultra 128GB provides.
K EXAONE 236B A23B (236B parameters) requires approximately 186.3 GB of memory with Q4_K_M quantization.
The recommended quantization for K EXAONE 236B A23B is Q4_K_M, which balances quality and memory efficiency.
On Mac Studio M2 Ultra 128GB, K EXAONE 236B A23B achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.
For coding workloads, K EXAONE 236B A23B on Mac Studio M2 Ultra 128GB receives a F grade with 2.0 tok/s and 4K context.
On Mac Studio M2 Ultra 128GB, K EXAONE 236B A23B can safely use up to 4K tokens of context. The model's official context limit is —, 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. Mac Studio M2 Ultra 128GB 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.
