Which Hardware Can Run Motif 3?

BF16 · 630.3 GB

Motif 3 (BF16) requires 630.3 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 820+ GB is recommended. Using the full 262K context window can add up to 45.2 GB, bringing total usage to 675.5 GB. No consumer GPU has enough memory.

Frequently Asked Questions

How much VRAM does Motif 3 need?

Motif 3 requires 630.3 GB of VRAM at BF16. Full 262K context adds up to 45.2 GB (675.5 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 314.8B × 16 bits ÷ 8 = 629.7 GB

KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 45.8 GB (at full 262K context)
