Can I run Seed-OSS 36B Instruct on Apple M1 (8GB)?

Compatibility verdict VRAM threshold engine
No, not enough memory would not load

No. Seed-OSS 36B Instruct needs ~22.5 GB even at Q4_K_M, but Apple M1 (8GB) only has ~5.5 GB usable.

Needs ~22.5 GB Device usable ~5.5 GB

Needs ~22.5 GB even at Q4_K_M, but only ~5.5 GB is usable.

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

The gap is about 17 GB: Seed-OSS 36B Instruct needs roughly 22.5 GB at Q4_K_M and Apple M1 (8GB) leaves only about 5.5 GB usable for a model. The lightest tracked hardware that runs Seed-OSS 36B Instruct is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Seed-OSS 36B Instruct on Nvidia GeForce RTX 4090 (24GB).

FAQ

Can Apple M1 (8GB) run Seed-OSS 36B Instruct?

No. Seed-OSS 36B Instruct needs ~22.5 GB even at Q4_K_M, but Apple M1 (8GB) only has ~5.5 GB usable.

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

Apple M1 (8GB) does not have enough memory. 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.
