Can I run Qwen2.5 3B on Apple M1 (8GB)?
Yes. Qwen2.5 3B runs on Apple M1 (8GB) at Q4_K_M (~3.3 GB of ~5.5 GB usable).
Runs at Q4_K_M using ~3.3 GB of ~5.5 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 M1 (8GB) leaves ~2.2 GB of headroom, room to step up to Q8_0 for higher quality.

Running cost · estimate

- Electricity / 1M tokens

- Pays for itself after
- ~2,270M tok
At ~$0.15/kWh and the estimated ~26 tok/s, a million generated tokens costs about $0.06 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$999 Apple M1 (8GB) pays for itself after roughly 2,270 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 M1 (8GB) run Qwen2.5 3B?
Yes. Qwen2.5 3B runs on Apple M1 (8GB) at Q4_K_M (~3.3 GB of ~5.5 GB usable).
How much memory does Qwen2.5 3B need?
Apple M1 (8GB) has room to spare. At Q4_K_M the weights are ~2.1 GB; with KV cache and runtime overhead, budget ~3.3 GB at a 4k context.
What is the best tool to run Qwen2.5 3B 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.
