Menlo/Jan-nano: what it needs to run
Menlo/Jan-nano is a fine-tune of Qwen/Qwen3-4B. Its configuration matches Qwen3-4B's on every field that decides memory, so Qwen3-4B's requirements are this repository's.

Geometrypublished data. Both configurations are published files, read at the revisions named below and compared field by field. Not a test that the model loads.Qwen3-4B (Qwen/Qwen3-4B) — every compared field is stated by both and equal.
Qwen3-4B: weight-file size by format
| Format | Size | Range | Basis |
|---|---|---|---|
| FP16 | 8.83 GB | 8.05 GB – 8.87 GB | reconstructed size |
| Q8_0 | 4.28 GB | exact | published data |
| Q6_K | 3.31 GB | exact | published data |
| Q5_K_M | 2.89 GB | exact | published data |
| Q5_0 | 2.82 GB | exact | published data |
| Q4_K_M | 2.50 GB | exact | published data |
| Q4_0 | 2.59 GB | 2.26 GB – 2.69 GB | reconstructed size |
| Q3_K_M | 2.25 GB | 1.92 GB – 2.41 GB | reconstructed size |
| Q2_K | 1.75 GB | 1.42 GB – 1.94 GB | reconstructed size |
These are Qwen3-4B’s sizes. A model with the same geometry quantizes to the same size, to within any difference in parameter count noted above. Which devices hold each, and how fast they run it, is on Qwen3-4B’s page.

It states the memory to run the model at Q4_K_M with 8,192 tokens of context — built on this repository’s own Q4_K_M file when it publishes one — and links back to this page, where the evidence is.
