Can I run DeepSeek-R1-0528-Qwen3-8B on iPhone 16?
No. DeepSeek-R1-0528-Qwen3-8B needs ~6.2 GB even at Q4_K_M, but iPhone 16 only has ~4.5 GB usable.
Needs ~6.2 GB even at Q4_K_M, but only ~4.5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 1.7 GB: DeepSeek-R1-0528-Qwen3-8B needs roughly 6.2 GB at Q4_K_M and iPhone 16 leaves only about 4.5 GB usable for a model. The lightest tracked hardware that runs DeepSeek-R1-0528-Qwen3-8B is the Nvidia GeForce RTX 3060 (12GB) at 12 GB. See DeepSeek-R1-0528-Qwen3-8B on Nvidia GeForce RTX 3060 (12GB).

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.
