Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 23.6 GB, but this setup only exposes 17.3 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, CodeLlama 13B Instruct requires more memory than Mac mini M2 24GB provides.
CodeLlama 13B Instruct (13B parameters) requires approximately 23.6 GB of memory with Q4_K_M quantization.
The recommended quantization for CodeLlama 13B Instruct is Q4_K_M, which balances quality and memory efficiency.
On Mac mini M2 24GB, CodeLlama 13B Instruct achieves approximately 5.3 tokens per second decode speed with a time-to-first-token of 36308ms using Q4_K_M quantization.
For coding workloads, CodeLlama 13B Instruct on Mac mini M2 24GB receives a F grade with 5.3 tok/s and 8K context.
On Mac mini M2 24GB, CodeLlama 13B Instruct can safely use up to 8K tokens of context. The model's official context limit is 16K, 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. Mac mini M2 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.
