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.

FAQ

How much RAM do I need to run Qwen3 14B on a phone?

At Q4_K_M, Qwen3 14B needs ~11.1GB of usable memory (weights + KV cache + runtime). In practice that means a 16GB+ Android phone or a 24GB+ iPhone — iOS lets a single app use less of its RAM than Android does.

How fast does Qwen3 14B run on a flagship phone?

On the OnePlus 13 (Snapdragon 8 Elite) it runs at ~3.8 tokens/s at Q4_K_M, estimated from memory bandwidth. Anything above ~8 tokens/s feels smooth for chat.

Can an iPhone run Qwen3 14B?

Not really: the best iPhone we track (iPhone Air) has ~7.8GB usable, but Qwen3 14B needs 11.1GB at Q4_K_M.

What is the best quantization of Qwen3 14B for mobile?

Q4_K_M (9GB download) is the size/quality sweet spot of the 4 quants available. Total memory needed is ~11.1GB once the KV cache and runtime are counted — the download size alone understates it.

How many phones can run Qwen3 14B?

59 of the 140 phones we track have enough estimated usable memory at Q4_K_M; 59 also reach our usable-speed threshold of 3 tokens/s, and 0 run smoothly. Memory-fit alone does not mean a good experience.

Which Macs can run Qwen3 14B?

52 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 14B good for on a phone?

It's tagged for chat, coding, reasoning. At 14.8B parameters, it prioritizes answer quality over speed — expect slower decoding.
