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 M3 24GB can run stablelm 2 zephyr 1 6b with a C grade (Runs well). Expected decode speed: 18.6 tok/s.
stablelm 2 zephyr 1 6b (6B parameters) requires approximately 7.9 GB of memory with Q4_K_M quantization.
The recommended quantization for stablelm 2 zephyr 1 6b is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 24GB, stablelm 2 zephyr 1 6b achieves approximately 18.6 tokens per second decode speed with a time-to-first-token of 10420ms using Q4_K_M quantization.
For coding workloads, stablelm 2 zephyr 1 6b on MacBook Pro M3 24GB receives a C grade with 18.6 tok/s and 230K context.
On MacBook Pro M3 24GB, stablelm 2 zephyr 1 6b can safely use up to 230K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M3 24GB 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.
