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 Pro 48GB can run LFM2 24B with a S grade (Runs well). Expected decode speed: 23.2 tok/s.
LFM2 24B (24B parameters) requires approximately 23.2 GB of memory with Q4_K_M quantization.
The recommended quantization for LFM2 24B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 48GB, LFM2 24B achieves approximately 23.2 tokens per second decode speed with a time-to-first-token of 8362ms using Q4_K_M quantization.
For coding workloads, LFM2 24B on MacBook Pro M4 Pro 48GB receives a S grade with 23.2 tok/s and 91K context.
On MacBook Pro M4 Pro 48GB, LFM2 24B can safely use up to 91K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Pro 48GB 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.
