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.

How much RAM do I need to run UI-Mate 9B on a phone?

At Q4_K_M, UI-Mate 9B needs ~7.4GB of usable memory (weights + KV cache + runtime). In practice that means a 12GB+ Android phone or a 12GB+ iPhone — iOS lets a single app use less of its RAM than Android does.

How fast does UI-Mate 9B run on a flagship phone?

On the OPPO Find X8 Pro (Dimensity 9400) it runs at ~6.5 tokens/s at Q4_K_M, estimated from memory bandwidth. Anything above ~8 tokens/s feels smooth for chat.

Can an iPhone run UI-Mate 9B?

Yes — the iPhone Air runs it at ~5.9 tokens/s at Q4_K_M, using 7.4GB of its ~7.8GB usable memory.

What is the best quantization of UI-Mate 9B for mobile?

Q4_K_M (5.9GB download) is the size/quality sweet spot of the 9 quants available. Total memory needed is ~7.4GB once the KV cache and runtime are counted — the download size alone understates it.

How many phones can run UI-Mate 9B?

105 of the 139 phones we track have enough estimated usable memory at Q4_K_M; 89 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 UI-Mate 9B?

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.
