Which Hardware Can Run Motif 3?
BF16 · 630.3 GBMotif 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)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Motif 3?
No — Motif 3 requires at least 630.3 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
Can I run Motif 3 on a Mac?
Motif 3 requires at least 630.3 GB at BF16. None of the 146 Macs we list has that much usable memory (the largest has 508.5 GB after macOS overhead).
Can I run Motif 3 locally?
