Devstral Small 2 24B: RAM and VRAM requirements
Devstral Small 2 24B needs about 15.4 GB to run at Q4_K_M (the Q4_K_M GGUF file is ~13.35 GB to download; KV cache and overhead add the rest), or about 25.3 GB at Q8_0. The lightest hardware that runs it is Apple M4 (24GB).

Q4_K_M and Q8_0 are GGUF download (file) sizes. Memory @ Q4 includes the KV cache and overhead, so it runs larger than the file on disk.
Will it run on your device?
Devstral Small 2 24B runs on 15 of 43 tracked devices at Q4_K_M.
Memory breakdown
How context length changes it
Longer context grows the KV cache quickly: Devstral Small 2 24B needs ~15.4 GB at 4k but ~51.8 GB at 128k, which can push it past a device that fits it at a short context.
Speed drops too: every token re-reads the KV cache, so at 128k context Devstral Small 2 24B generates at roughly ~26% of its short-context speed. How this is estimated.
Quantization sizes
| Quantization | Size on disk |
|---|---|
| Q2_K | 10.1 GB est |
| Q3_K_M | 11.7 GB est |
| Q4_K_M (default) | 13.35 GB |
| Q5_K_M | 17.1 GB est |
| Q6_K | 19.7 GB est |
| Q8_0 | 23.33 GB |
| FP16 | 48.03 GB |
Lower quant = smaller and faster, slightly lower quality. Q4_K_M is the common default.
