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 Fara 1.5 4B on a phone?
At Q4_K_M, Fara 1.5 4B needs ~4GB of usable memory (weights + KV cache + runtime). In practice that means a 6GB+ Android phone or a 8GB+ iPhone — iOS lets a single app use less of its RAM than Android does.
How fast does Fara 1.5 4B run on a flagship phone?
On the OPPO Find X8 Pro (Dimensity 9400) it runs at ~13.2 tokens/s at Q4_K_M, estimated from memory bandwidth. Anything above ~8 tokens/s feels smooth for chat.
Can an iPhone run Fara 1.5 4B?
Yes — the iPhone Air runs it at ~11.9 tokens/s at Q4_K_M, using 4GB of its ~7.8GB usable memory.
What is the best quantization of Fara 1.5 4B for mobile?
Q4_K_M (2.9GB download) is the size/quality sweet spot of the 9 quants available. Total memory needed is ~4GB once the KV cache and runtime are counted — the download size alone understates it.
How many phones can run Fara 1.5 4B?
132 of the 135 phones we track have enough estimated usable memory at Q4_K_M; 122 also reach our usable-speed threshold of 3 tokens/s, and 95 run smoothly. Memory-fit alone does not mean a good experience.
What is Fara 1.5 4B good for on a phone?
It's tagged for vision, reasoning. At 4.5B parameters, it balances quality and speed for daily use.
