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.

Inference speed
Estimated decode speed (tokens/sec) for Yi Coder 9B at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~126 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Yes, MacBook Pro M3 Pro 36GB can run Yi Coder 9B with a B grade (Runs well). Expected decode speed: 21.7 tok/s.
Yi Coder 9B (9B parameters) requires approximately 11.7 GB of memory with Q4_K_M quantization.
The recommended quantization for Yi Coder 9B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 Pro 36GB, Yi Coder 9B achieves approximately 21.7 tokens per second decode speed with a time-to-first-token of 8926ms using Q4_K_M quantization.
For coding workloads, Yi Coder 9B on MacBook Pro M3 Pro 36GB receives a B grade with 21.7 tok/s and 131K context.
On MacBook Pro M3 Pro 36GB, Yi Coder 9B can safely use up to 131K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Not always. MacBook Pro M3 Pro 36GB 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.
