Inference speed
Devstral Small 1.1 inference speed — tokens per second by GPU & Mac
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.
