Can RTX 3070 8GB run Devstral-Small-2507?

NVIDIA · 8 GB GDDR6 · 448 GB/s bandwidth · Mistral · 23.6B · model ctx up to 128K

No — Devstral-Small-2507 at Q4 needs ≈ 16.34 GB even at 4K context, beyond the RTX 3070 8GB's 8 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 6.3 tok/s (estimated, batch 1). FP16 needs ≈ 52.92 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	16.34 GB	No	8.3 est.
Q4	8K default	18.7 GB	No	6.3 est.
Q4	32K	32.86 GB	No	—
FP16	4K	50.56 GB	No	—
FP16	8K default	52.92 GB	No	—
FP16	32K	67.08 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).
