Run DeepSeek V4 Flash Vision Exp locally

DeepSeek V4 Flash Vision Exp is 284B parameters (13B active per token — a mixture-of-experts, so it still needs room for all 284B in memory). Here's the VRAM it needs at each quantization, the smallest GPU that fits, and how a self-hosted box compares with the cheapest verified API.

VRAM by quantization

VRAM ≈ params × bytes/param × 1.2 (overhead). See the fullmethod and break-even calculator.

Self-host vs API

Cheapest API for DeepSeek V4 Flash Vision Exp is $0.862 / 1M tokens(blended) via DeepInfra. Running it yourself in int4 fits a4× H100 (320 GB) at $6.92/hr — about $5,051.6/month at 24/7. Those two lines cross at roughly 5.9B tokens/month: below that the API wins on cost, above it the dedicated GPU does (assuming you keep it busy). Tune your own volume in the break-even calculator.

Run it at home

No cloud account needed: DeepSeek V4 Flash Vision Exp in int4 (170.4 GB) fits a Mac Studio M5 Ultra (256 GB unified), a $9,499 one-off buy. Amortized over 3 years that's about $0.3615/hr — hardware only, electricity aside. Against the DeepInfra API at $0.862/1M, buying it pays for itself after roughly 11.0B tokens total. Below that the API is cheaper; a machine that mostly sits idle rarely earns back its price.
