GPUs that would let you run this model locally:

NVIDIA RTX 4090~$1,799

Best consumer card for local LLMs — runs most 30B models at Q4-Q5.

NVIDIA RTX 3090~$999

Same VRAM as 4090 at half the price on the used market.

FAQ

Can the NVIDIA RTX 4070 run DeepSeek V4 Flash?

No. DeepSeek V4 Flash (37.0B) needs at least 23.4GB even at its smallest quantization, more than the 12.0GB on the NVIDIA RTX 4070.

What's the best quantization to use?

None of DeepSeek V4 Flash's available quantizations fit in 12.0GB. You'll need either a larger GPU, a smaller model, or to run it in the cloud.

What if I need more headroom for context length?

KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
