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, MacBook Pro M4 Max 128GB can run starcoder2 15b instruct v0.1 with a C grade (Runs well). Expected decode speed: 34.7 tok/s.
starcoder2 15b instruct v0.1 (15B parameters) requires approximately 25.6 GB of memory with Q4_K_M quantization.
The recommended quantization for starcoder2 15b instruct v0.1 is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Max 128GB, starcoder2 15b instruct v0.1 achieves approximately 34.7 tokens per second decode speed with a time-to-first-token of 5573ms using Q4_K_M quantization.
For coding workloads, starcoder2 15b instruct v0.1 on MacBook Pro M4 Max 128GB receives a C grade with 34.7 tok/s and 622K context.
On MacBook Pro M4 Max 128GB, starcoder2 15b instruct v0.1 can safely use up to 622K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Max 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.
