DeepSeek V4 Flash Vision Exp VRAM Requirements

DeepSeek, China · Released August 31, 2026

DeepSeek V4 Flash Vision Exp has 304.6B parameters (15B active per token). In BF16 its weights alone take 530 GiB; quantized to 4-bit, about 160 GiB. Each 32K-token request adds 0.20 GiB of KV cache. Cheapest way to run it today: 7 × GeForce RTX 3090 (24 GB) at $1.00 per hour.

VRAM by precision and context length

Weights plus the KV cache of one request (BF16 cache) and the model's fixed recurrent state, in GiB. Add 1 to 3 GiB for the inference engine itself.

How many GPUs to run DeepSeek V4 Flash Vision Exp

Fewest GPUs that fit the weights plus one 8K-token request. Data-center GPUs use vLLM (90% of memory usable), the others llama.cpp. Several GPUs split the model with tensor or pipeline parallelism.

Cheapest way to run DeepSeek V4 Flash Vision Exp today

For each GPU: the fewest cards that fit DeepSeek V4 Flash Vision Exp with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-10-10).

On-demand prices from RunPod, Vast.ai, Verda and Azure, checked every hour. Serving many users needs more KV cache, so more memory: size it in the calculator. Some links are affiliate links: StudioTV may earn a commission, at no extra cost to you.

KV cache: how memory grows with context

Architecture: 43 layers · 512-wide latent, 128-token window + compression (21 layers 4×, 20 layers 128×). Its KV cache is 6.9× smaller than if every layer used full attention, because it keeps only a short window of tokens at full detail and compresses the rest of the sequence. Only 15B parameters are active per token, but all 305B must sit in memory: VRAM depends on the total, speed on the active part.

DeepSeek V4 Flash Vision Exp VRAM FAQ

How much VRAM does DeepSeek V4 Flash Vision Exp need?

In BF16 the weights alone take 530 GiB (570 GB). In FP8 that is 266 GiB, and about 160 GiB with 4-bit quantization (Q4_K_M); the official FP8 checkpoint is 146 GiB. Each request then adds KV cache: 0.05 GiB at 8K tokens and 0.20 GiB at 32K (BF16 cache).

Can DeepSeek V4 Flash Vision Exp run on a single RTX 4090 (24 GB)?

No. Even in 4-bit it needs 8 RTX 4090s. In 4-bit it needs 3 H100 GPUs.

What is the cheapest way to run DeepSeek V4 Flash Vision Exp?

On 2026-10-10, the cheapest on-demand setup is 7 × GeForce RTX 3090 (24 GB) with FP8 weights on Vast.ai, at $1.00 per hour (about $730.73 per month). Next: 4 × RTX 6000 Ada (48 GB) with FP8 weights on Vast.ai, at $1.98 per hour. Sized for one 8K-token request; prices are checked every hour.

How many H100 GPUs does DeepSeek V4 Flash Vision Exp need?

With one request and an 8K-token context: 8 in BF16, 4 in FP8 and 3 in 4-bit (vLLM, 90% of memory usable). Serving many users at once needs more memory for their KV caches: the calculator sizes that for you.
