What is DeepSeek V4 Flash 0731?

DeepSeek V4 Flash 0731 is DeepSeek's official release of V4 Flash from July 2026, replacing the preview with substantially stronger agentic skills, according to its card. It is a mixture-of-experts model with about 284B total and about 14B activated parameters, a one-million-token context and an attached speculative decoding module. It answers directly in chat mode or reasons first in thinking mode, with low, high or max reasoning effort. The weights are MIT licensed.

Memory needed by quant and context

Graphics card memory in GB: weights loaded on the GPU + f16 KV cache + compute buffer. Add about 0.6 GB if the GPU also drives your display on Windows. Part of the file stays off the graphics card: llama.cpp keeps the input embedding table in system RAM. A Mac counts the whole file, so it needs a little more.

Frequently asked questions

How much VRAM does DeepSeek V4 Flash 0731 need?

At MXFP4 the file is 154.99 GB; with 8k context a graphics card needs about 155.1 GB (weights 154.42 GB, KV cache 0.1 GB, compute buffer 0.6 GB). The smallest tracked file (Q2_K (heavy quality loss)) needs about 117.4 GB. Part of the file stays off the graphics card: llama.cpp keeps the input embedding table in system RAM. A Mac counts the whole file, so it needs a little more.

What is the cheapest GPU that runs DeepSeek V4 Flash 0731 well?

No GPU with a current street price reaches Runs great or Runs well at MXFP4. The best tracked option is Apple M5 Ultra · 256 GB: Runs great.

Can DeepSeek V4 Flash 0731 run on an 8 GB, 16 GB or 24 GB GPU?

At MXFP4 with 8k context: GeForce RTX 4060 — Won't run; GeForce RTX 5060 Ti 16GB — Won't run; GeForce RTX 3090 — Won't run.

Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
