Inference speed
Estimated decode speed (tokens/sec) for Devstral Small 1.1 at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~88 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Quantization
How much VRAM Devstral Small 1.1 (24B) needs at each GGUF quant, and whether it fits a 24 GB card (RTX 4090 / 3090). The recommended Q4_K_M uses ~14.6 GB — about 43% less VRAM than Q8_0, at a small quality cost.
| Quant | Bits | VRAM (weights) | Quality | Fits 24 GB? |
|---|---|---|---|---|
| Q2_K | 2 | 9.4 GB | Low | Fits |
| Q3_K_S | 3 | 11.8 GB | Low | Fits |
| NVFP4 | 4 | 13.4 GB | Medium | Fits |
| Q4_K_Mrecommended | 4 | 14.6 GB | Medium | Tight |
| Q5_K_M | 5 | 17.3 GB | High | Offloads |
| Q6_K | 6 | 19.7 GB | High | Offloads |
| Q8_0 | 8 | 25.7 GB | Very High | Too big |
| F16 | 16 | 49.2 GB | Maximum | Too big |
VRAM shown is quantized weights only; add ~1–3 GB runtime overhead plus KV cache for your context length. Lower quants trade quality for memory — Q4_K_M is the usual sweet spot; Q2/Q3 only when you must fit a bigger model.
