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 Max 48GB can run internlm2 math plus 20b i1 with a C grade (Runs well). Expected decode speed: 35.6 tok/s.
internlm2 math plus 20b i1 (20B parameters) requires approximately 20.6 GB of memory with Q4_K_M quantization.
The recommended quantization for internlm2 math plus 20b i1 is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Max 48GB, internlm2 math plus 20b i1 achieves approximately 35.6 tokens per second decode speed with a time-to-first-token of 5445ms using Q4_K_M quantization.
For coding workloads, internlm2 math plus 20b i1 on MacBook Pro M4 Max 48GB receives a C grade with 35.6 tok/s and 111K context.
On MacBook Pro M4 Max 48GB, internlm2 math plus 20b i1 can safely use up to 111K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Max 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.
