DeepSeek v3 — Hardware Requirements & GPU Compatibility
Chat
Released in December 2024, DeepSeek V3 is a large chat-oriented language model from DeepSeek with roughly 684 billion parameters, placing it among the largest openly released checkpoints of its generation. It is built for general conversational and instruction-following use rather than a narrow specialty. With a 160K token context window, DeepSeek V3 can process long documents and extended multi-turn conversations in a single pass without truncation. At this parameter scale, it needs multi-GPU or server-class hardware to run at all; most users will reach it through a hosted endpoint rather than attempting to run it locally on their own machine.

Frequently Asked Questions
- How much VRAM does DeepSeek v3 need?
DeepSeek v3 requires 414.6 GB of VRAM at Q4_K_M, or 1372.9 GB at BF16. Full 164K context adds up to 283.0 GB (697.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 684.5B × 4.8 bits ÷ 8 = 410.7 GB
KV Cache + Overhead ≈ 3.9 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 286.9 GB (at full 164K context)
VRAM usage by quantization
Q4_K_M414.6 GBQ4_K_M + full context697.6 GB- Can NVIDIA GeForce RTX 5090 run DeepSeek v3?
No — DeepSeek v3 requires at least 294.8 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- What's the best quantization for DeepSeek v3?
For DeepSeek v3, Q4_K_M (414.6 GB) offers the best balance of quality and VRAM usage. Q5_K_M (491.6 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 294.8 GB.
