Can I run Sarvam-105B on Apple M4 Pro (24GB)?

Compatibility verdict VRAM threshold engine

No, not enough memory would not load

No. Sarvam-105B needs ~67.5 GB even at Q4_K_M, but Apple M4 Pro (24GB) only has ~16 GB usable.

Needs ~67.5 GB Device usable ~16 GB

Needs ~67.5 GB even at Q4_K_M, but only ~16 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 51.5 GB: Sarvam-105B needs roughly 67.5 GB at Q4_K_M and Apple M4 Pro (24GB) leaves only about 16 GB usable for a model. The lightest tracked hardware that runs Sarvam-105B is the Apple M4 Max (128GB) at 128 GB. See Sarvam-105B on Apple M4 Max (128GB).

How to run it

On macOS use LM Studio (Polished GUI, ships MLX on Apple Silicon, one-click model downloads.).

FAQ

Can Apple M4 Pro (24GB) run Sarvam-105B?

No. Sarvam-105B needs ~67.5 GB even at Q4_K_M, but Apple M4 Pro (24GB) only has ~16 GB usable.

How much memory does Sarvam-105B need?

Apple M4 Pro (24GB) does not have enough memory. At Q4_K_M the weights are ~64.2 GB; with KV cache and runtime overhead, budget ~67.5 GB at a 4k context. It is a Mixture-of-Experts model (105B total / 10.3B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Sarvam-105B on macOS?

LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
