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.

Inference speed
Estimated decode speed (tokens/sec) for Hermes 4.3 36B at Q4_K_M across popular GPUs and Apple Silicon, including multi-GPU rigs, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~55 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Yes, Mac Studio M2 Ultra 128GB can run Hermes 4.3 36B with a C grade (Runs well). Expected decode speed: 21.1 tok/s.
Hermes 4.3 36B (36B parameters) requires approximately 40.9 GB of memory with Q4_K_M quantization.
The recommended quantization for Hermes 4.3 36B is Q4_K_M, which balances quality and memory efficiency.
On Mac Studio M2 Ultra 128GB, Hermes 4.3 36B achieves approximately 21.1 tokens per second decode speed with a time-to-first-token of 9163ms using Q4_K_M quantization.
For coding workloads, Hermes 4.3 36B on Mac Studio M2 Ultra 128GB receives a C grade with 21.1 tok/s and 210K context.
On Mac Studio M2 Ultra 128GB, Hermes 4.3 36B can safely use up to 210K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
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.
