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 Air M2 16GB can run DevStral 7B with a A grade (Runs well). Expected decode speed: 16.4 tok/s.
DevStral 7B (7B parameters) requires approximately 8.9 GB of memory with Q4_K_M quantization.
The recommended quantization for DevStral 7B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Air M2 16GB, DevStral 7B achieves approximately 16.4 tokens per second decode speed with a time-to-first-token of 11831ms using Q4_K_M quantization.
For coding workloads, DevStral 7B on MacBook Air M2 16GB receives a A grade with 16.4 tok/s and 8K context.
On MacBook Air M2 16GB, DevStral 7B 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 Air M2 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.
