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 Laguna XS 2.1 on a phone?

At Q4_K_M, Laguna XS 2.1 needs ~24.2GB of usable memory (weights + KV cache + runtime). In practice that means no current Android phone or no current iPhone — iOS lets a single app use less of its RAM than Android does.

How fast does Laguna XS 2.1 run on a flagship phone?

It doesn't fit on any of the 140 phones we track at Q4_K_M — it needs ~24.2GB of usable memory.

Can an iPhone run Laguna XS 2.1?

Not really: the best iPhone we track (iPhone 16 Pro Max) has ~5.2GB usable, but Laguna XS 2.1 needs 24.2GB at Q4_K_M.

What is the best quantization of Laguna XS 2.1 for mobile?

Q4_K_M (20.3GB download) is the size/quality sweet spot. Total memory needed is ~24.2GB once the KV cache and runtime are counted — the download size alone understates it.

How many phones can run Laguna XS 2.1?

0 of the 140 phones we track have enough estimated usable memory at Q4_K_M; 0 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 Laguna XS 2.1?

36 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 Laguna XS 2.1 good for on a phone?

It's tagged for coding, reasoning. At 33B parameters (3B active — it's a MoE, so it decodes faster than its size suggests), it prioritizes answer quality over speed — expect slower decoding.
