Frequently Asked Questions
- How much VRAM does Snowflake Arctic Instruct need?
Snowflake Arctic Instruct requires 957.8 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 478.6B × 16 bits ÷ 8 = 957.2 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 0.9 GB (at full 4K context)
