Frequently Asked Questions

How much VRAM does Inkling Small DSpark Preview need?

Inkling Small DSpark Preview requires 1.2 GB of VRAM at Q4_K_M, or 3.1 GB at BF16. Full 1049K context adds up to 21.4 GB (22.6 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 1.4B × 4.8 bits ÷ 8 = 0.8 GB

KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead ≈ 21.8 GB (at full 1049K context)
