Can I Run Devstral Small 2 24B on NVIDIA GeForce RTX 3070?
Written by Jakub Rusinowski · Last updated September 11, 2026
No. Devstral Small 2 24B needs 16.6 GB at 8K context (14.5 GB weights + 2.1 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 3070 has only 8 GB. No quantization we publish closes a gap that size.

Devstral Small 2 24B on the NVIDIA GeForce RTX 3070: VRAM by quantization

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 8 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 3070: 8K 16.6 GB ✗ · 32K 20.7 GB ✗ · 128K 36.8 GB ✗. Past 8K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Either step down to a smaller size in this family, or move to a AMD Radeon RX 7900 XT (20 GB), the card with the least memory we track that holds it.
No compatible GPU? Devstral on 16 GB of system RAM, CPU only: runs, but it is tight.
