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 32GB can run StarCoder2 15B with a C grade (Runs well). Expected decode speed: 8.7 tok/s.
StarCoder2 15B (15B parameters) requires approximately 15.3 GB of memory with Q4_K_M quantization.
The recommended quantization for StarCoder2 15B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 32GB, StarCoder2 15B achieves approximately 8.7 tokens per second decode speed with a time-to-first-token of 22189ms using Q4_K_M quantization.
For coding workloads, StarCoder2 15B on MacBook Pro M4 32GB receives a C grade with 8.7 tok/s and 87K context.
On MacBook Pro M4 32GB, StarCoder2 15B can safely use up to 87K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 32GB 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.
