Can I run Seed-OSS 36B Instruct on Apple M4 Max (64GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs usable speed ~22 tok/s est.

Yes. Seed-OSS 36B Instruct runs on Apple M4 Max (64GB) at Q4_K_M (~22.5 GB of ~48 GB usable).

Needs ~22.5 GB Device usable ~48 GB

Runs at Q4_K_M using ~22.5 GB of ~48 GB usable. You have room for Q8_0 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M4 Max (64GB) leaves ~25.5 GB of headroom, room to step up to Q8_0 for higher quality.

Running cost · estimate

Power & economics est.

Electricity / 1M tokens

Pays for itself after
~15,213M tok

At ~$0.15/kWh and the estimated ~22 tok/s, a million generated tokens costs about $0.27 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$3,499 Apple M4 Max (64GB) pays for itself after roughly 15,213 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 Max (64GB) run Seed-OSS 36B Instruct?

Yes. Seed-OSS 36B Instruct runs on Apple M4 Max (64GB) at Q4_K_M (~22.5 GB of ~48 GB usable).

How much memory does Seed-OSS 36B Instruct need?

Apple M4 Max (64GB) has room to spare. At Q4_K_M the weights are ~20.27 GB; with KV cache and runtime overhead, budget ~22.5 GB at a 4k context.

What is the best tool to run Seed-OSS 36B Instruct 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.
