Hardware requirements

What hardware do I need to run Devstral Small 2 24B?

24B 384K context Apache 2.0

At Q4_K_M the weights are 13.5 GB; with an 8K KV cache and runtime overhead that is 15.3 GB, so it wants a 20 GB card to run with headroom — in practice 20 GB VRAM: Radeon RX 7900 XT and 1 other. Every figure below is computed from the model’s published shape against each device’s usable memory; tokens per second are estimates. The method.

Minimum practical 16 GB VRAM

GeForce RTX 5080 — Q3_K_M, 12.8 GB of 14.4 GB, ~53 tok/s, up to 18K context.

Also: GeForce RTX 5070 Ti, GeForce RTX 4080 Super, GeForce RTX 4080, GeForce RTX 4070 Ti Super, Radeon RX 9070 XT +12 more
the smallest card that holds it at all, at Q3_K_M — the lowest quantisation worth running
Recommended 20 GB VRAM

Radeon RX 7900 XT — Q4_K_M, 15.3 GB of 18.4 GB, ~36 tok/s, up to 27K context.

Also: RTX 4000 Ada
runs the recommended quantisation with headroom at 8K context
High quality 32 GB VRAM

GeForce RTX 5090 — Q8_0, 25.6 GB of 30.4 GB, ~46 tok/s, up to 38K context.

Also: RTX 5000 Ada, Radeon Pro W7800
near-lossless Q8_0 with headroom
Long context 48 GB VRAM

RTX 6000 Ada — Q4_K_M, 34.1 GB of 46.4 GB, ~43 tok/s at 128K.

Also: L40S, Radeon Pro W7900, RTX A6000
128K tokens (or the model’s maximum) at the recommended quantisation
Apple Silicon 32 GB unified

M1 Pro · 32 GB — Q4_K_M, 15.3 GB of 24.0 GB, ~8.3 tok/s, up to 63K context.

Also: M2 Pro · 32 GB, M4 · 32 GB

Totals add 0.6 GB runtime overhead and an f16 KV cache; "needs" is the smallest discrete card class whose usable memory (after display and driver reserve) leaves 15% headroom. A q8_0 cache roughly halves the KV columns.
