Yi 1.5 6B needs ~7.3 GB VRAM. MacBook Pro M1 Pro 16GB has 11.5 GB. With Q4_K_M quantization, expect ~39 tok/s.
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.

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 M1 Pro 16GB can run Yi 1.5 6B with a C grade (Runs well). Expected decode speed: 38.6 tok/s.
Yi 1.5 6B (6B parameters) requires approximately 7.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Yi 1.5 6B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M1 Pro 16GB, Yi 1.5 6B achieves approximately 38.6 tokens per second decode speed with a time-to-first-token of 5012ms using Q4_K_M quantization.
For coding workloads, Yi 1.5 6B on MacBook Pro M1 Pro 16GB receives a C grade with 38.6 tok/s and 4K context.
On MacBook Pro M1 Pro 16GB, Yi 1.5 6B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.
Not always. MacBook Pro M1 Pro 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.
