Frequently Asked Questions

How much VRAM does Olmo 3 7B Instruct SFT need?

Olmo 3 7B Instruct SFT requires 5.8 GB of VRAM at Q4_K_M, or 16.0 GB at BF16. Full 66K context adds up to 9.1 GB (14.9 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 7.3B × 4.8 bits ÷ 8 = 4.4 GB

KV Cache + Overhead ≈ 1.3 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 ≈ 10.5 GB (at full 66K context)
