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 Ministral 3 3B on a phone?

At Q4_K_M, Ministral 3 3B needs ~3GB 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 Ministral 3 3B run on a flagship phone?

On the Galaxy S25 Ultra (Snapdragon 8 Elite) it runs at ~16.5 tokens/s at Q4_K_M, estimated from memory bandwidth. Anything above ~8 tokens/s feels smooth for chat.

Can an iPhone run Ministral 3 3B?

Yes — the iPhone Air runs it at ~16.5 tokens/s at Q4_K_M, using 3GB of its ~7.8GB usable memory.

What is the best quantization of Ministral 3 3B for mobile?

Q4_K_M (2.1GB download) is the size/quality sweet spot of the 3 quants available. Total memory needed is ~3GB once the KV cache and runtime are counted — the download size alone understates it.

How many phones can run Ministral 3 3B?

139 of the 140 phones we track have enough estimated usable memory at Q4_K_M; 139 also reach our usable-speed threshold of 3 tokens/s, and 103 run smoothly. Memory-fit alone does not mean a good experience.

Which Macs can run Ministral 3 3B?

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.
