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 S 2.1 on a phone?

At Q4_K_M, Laguna S 2.1 needs ~109.7GB 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 S 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 ~109.7GB of usable memory.

Can an iPhone run Laguna S 2.1?

Not really: the best iPhone we track (iPhone 16 Pro Max) has ~5.2GB usable, but Laguna S 2.1 needs 109.7GB at Q4_K_M.

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

Q4_K_M (96GB download) is the size/quality sweet spot of the 2 quants available. Total memory needed is ~109.7GB once the KV cache and runtime are counted — the download size alone understates it.

How many phones can run Laguna S 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 S 2.1?

9 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 S 2.1 good for on a phone?

It's tagged for coding, reasoning. At 118B parameters (8B active — it's a MoE, so it decodes faster than its size suggests), it prioritizes answer quality over speed — expect slower decoding.
