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 M3 Pro 18GB can run Mistral 7B Instruct v0.3 with a B grade (Runs well). Expected decode speed: 27.6 tok/s.
Mistral 7B Instruct v0.3 (7B parameters) requires approximately 9.1 GB of memory with Q4_K_M quantization.
The recommended quantization for Mistral 7B Instruct v0.3 is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 Pro 18GB, Mistral 7B Instruct v0.3 achieves approximately 27.6 tokens per second decode speed with a time-to-first-token of 7023ms using Q4_K_M quantization.
For coding workloads, Mistral 7B Instruct v0.3 on MacBook Pro M3 Pro 18GB receives a B grade with 27.6 tok/s and 8K context.
On MacBook Pro M3 Pro 18GB, Mistral 7B Instruct v0.3 can safely use up to 8K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
Not always. MacBook Pro M3 Pro 18GB 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.
