Can RTX 4070 12GB run Devstral-Small-2-24B-Instruct-2512?

NVIDIA · 12 GB GDDR6X · 504 GB/s bandwidth · Mistral · 24.0B · model ctx up to 256K

No — Devstral-Small-2-24B-Instruct-2512 at Q4 needs ≈ 16.6 GB even at 4K context, beyond the RTX 4070 12GB's 12 GB GDDR6X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 15.2 tok/s (estimated, batch 1). FP16 needs ≈ 53.8 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	16.6 GB	No	20.0 est.
Q4	8K default	19.0 GB	No	15.2 est.
Q4	32K	33.4 GB	No	4.9 est.
FP16	4K	51.4 GB	No	—
FP16	8K default	53.8 GB	No	—
FP16	32K	68.2 GB	No	—

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
