Can I run Llama 3.1 8B on iPad Pro M4 (16GB, 1TB/2TB config)?
Yes. Llama 3.1 8B runs on iPad Pro M4 (16GB, 1TB/2TB config) at Q4_K_M (~6.4 GB of ~12 GB usable).
Runs at Q4_K_M using ~6.4 GB of ~12 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. iPad Pro M4 (16GB, 1TB/2TB config) leaves ~5.6 GB of headroom, room to step up to Q8_0 for higher quality.

Which quant fits
Running cost · estimate
- Power draw
- ~14 W
- Electricity / 1M tokens
- ~$0.05
- Pays for itself after
- ~3,553M tok
At ~$0.15/kWh and the estimated ~12 tok/s, a million generated tokens costs about $0.05 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,599 iPad Pro M4 (16GB, 1TB/2TB config) pays for itself after roughly 3,553 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.
How to run it
On iOS use Apple Foundation Models (Built into iOS 26, ~3B on-device model, zero download, fully private.).

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.
