OpenChat 7B needs ~17.5 GB VRAM. MacBook Pro M2 Max 96GB has 69.1 GB. With Q4_K_M quantization, expect ~58 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 M2 Max 96GB can run OpenChat 7B with a C grade (Runs well). Expected decode speed: 58.4 tok/s.
OpenChat 7B (7B parameters) requires approximately 17.5 GB of memory with Q4_K_M quantization.
The recommended quantization for OpenChat 7B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M2 Max 96GB, OpenChat 7B achieves approximately 58.4 tokens per second decode speed with a time-to-first-token of 3315ms using Q4_K_M quantization.
For coding workloads, OpenChat 7B on MacBook Pro M2 Max 96GB receives a C grade with 58.4 tok/s and 8K context.
On MacBook Pro M2 Max 96GB, OpenChat 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 Pro M2 Max 96GB 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.
