Can I run Sarvam-1 2B on Apple M4 Pro (24GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~141 tok/s est.

Yes. Sarvam-1 2B runs on Apple M4 Pro (24GB) at Q4_K_M (~2.7 GB of ~16 GB usable).

Needs ~2.7 GB Device usable ~16 GB

Runs at Q4_K_M using ~2.7 GB of ~16 GB usable. You have room for FP16 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M4 Pro (24GB) leaves ~13.3 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

Power & economics est.
Power draw
~140 W
Electricity / 1M tokens
~$0.04
Pays for itself after
~4,346M tok

At ~$0.15/kWh and the estimated ~141 tok/s, a million generated tokens costs about $0.04 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,999 Apple M4 Pro (24GB) pays for itself after roughly 4,346 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ

Can Apple M4 Pro (24GB) run Sarvam-1 2B?

Yes. Sarvam-1 2B runs on Apple M4 Pro (24GB) at Q4_K_M (~2.7 GB of ~16 GB usable).

How much memory does Sarvam-1 2B need?

Apple M4 Pro (24GB) has room to spare. At Q4_K_M the weights are ~1.55 GB; with KV cache and runtime overhead, budget ~2.7 GB at a 4k context.

What is the best tool to run Sarvam-1 2B 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.
