Devstral Small 2505 24B on the NVIDIA GeForce RTX 5070 Ti: VRAM by quantization

|---|---|---|---|---|
| F16 | 49.5 GB | ✗ No | — | — |
| Q8_0 | 27 GB | ✗ No | — | — |
| Q6_K | 21.2 GB | ✗ No | — | — |

| Q2_K | 9.4 GB | ✓ Yes | 32K | — |
Assumes a 4K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 16 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 5070 Ti: 8K 16.6 GB ✗ · 32K 20.7 GB ✗ · 128K 36.8 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
