Qwen3 4B
At the default Q4_K_M, 139 of 140 phones have enough estimated usable memory; 139 also reach 3+ tokens/s. On Mac, 54 of 54 exact configurations pass using that quant or a smaller tracked fallback.
Downloads & memory by quant
The download is only the weights — add KV cache and runtime to get what your phone actually needs. “Memory-fit” only means it can load; “usable” also requires an estimated 3+ tokens/s. Each row uses that row's quant. ★ = recommended.
| Quant | Download | Memory needed | Phone reality |
|---|---|---|---|
| Q4_K_M ★ | 2.5 GB | ~3.5 GB | 139 memory-fit · 139 usable |
| Q5_K_M | 2.9 GB | ~3.9 GB | 137 memory-fit · 125 usable |
| Q6_K | 3.3 GB | ~4.3 GB | 137 memory-fit · 125 usable |
| Q8_0 | 4.3 GB | ~5.4 GB | 130 memory-fit · 97 usable |

FAQ
How much RAM do I need to run Qwen3 4B on a phone?
At Q4_K_M, Qwen3 4B needs ~3.5GB of usable memory (weights + KV cache + runtime). In practice that means a 6GB+ Android phone or a 6GB+ iPhone — iOS lets a single app use less of its RAM than Android does.
How fast does Qwen3 4B run on a flagship phone?
On the OPPO Find X8 Pro (Dimensity 9400) it runs at ~15.4 tokens/s at Q4_K_M, estimated from memory bandwidth. Anything above ~8 tokens/s feels smooth for chat.
Can an iPhone run Qwen3 4B?
Yes — the iPhone Air runs it at ~13.8 tokens/s at Q4_K_M, using 3.5GB of its ~7.8GB usable memory.
What is the best quantization of Qwen3 4B for mobile?
Q4_K_M (2.5GB download) is the size/quality sweet spot of the 4 quants available. Total memory needed is ~3.5GB once the KV cache and runtime are counted — the download size alone understates it.

Which Macs can run Qwen3 4B?
54 of the 54 exact Mac configurations we track have enough estimated working memory. Each Mac uses the recommended Q4_K_M when it fits, or the largest smaller tracked quant that fits, and separates installed unified memory, the macOS reserve, and estimated speed.
What is Qwen3 4B good for on a phone?
