Cerebras-GPT 13B needs ~22.1 GB but MacBook Pro M4 16GB only has 11.5 GB. Try a smaller quantization or lighter model.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 22.1 GB, but this setup only exposes 11.5 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, Cerebras-GPT 13B requires more memory than MacBook Pro M4 16GB provides.
Cerebras-GPT 13B (13B parameters) requires approximately 22.1 GB of memory with Q5_K_M quantization.
The recommended quantization for Cerebras-GPT 13B is Q5_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 16GB, Cerebras-GPT 13B achieves approximately 3.7 tokens per second decode speed with a time-to-first-token of 51924ms using Q5_K_M quantization.
For coding workloads, Cerebras-GPT 13B on MacBook Pro M4 16GB receives a F grade with 3.7 tok/s and 4K context.
On MacBook Pro M4 16GB, Cerebras-GPT 13B can safely use up to 4K tokens of context. The model's official context limit is 131K, 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. MacBook Pro M4 16GB 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.
