Frequently Asked Questions
How much VRAM does DeepSeek v2 Lite Chat need?
DeepSeek v2 Lite Chat requires 10.2 GB of VRAM at Q4_K_M, or 32.2 GB at BF16. Full 164K context adds up to 4.6 GB (14.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 15.7B × 4.8 bits ÷ 8 = 9.4 GB
KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 5.4 GB (at full 164K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run DeepSeek v2 Lite Chat?
Yes, at Q8_0 (16.5 GB) or lower. Higher quantizations like BF16 (32.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for DeepSeek v2 Lite Chat?
For DeepSeek v2 Lite Chat, Q4_K_M (10.2 GB) offers the best balance of quality and VRAM usage. Q5_0 (10.6 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 5.1 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run DeepSeek v2 Lite Chat on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run DeepSeek v2 Lite Chat. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 10.2 GB of usable unified memory (RAM minus macOS overhead).
Can I run DeepSeek v2 Lite Chat locally?
Yes — DeepSeek v2 Lite Chat can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is DeepSeek v2 Lite Chat?
At Q4_K_M, DeepSeek v2 Lite Chat can reach ~174 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~243 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)
Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.
Example: NVIDIA B200 → 1.7 GB active ÷ (8000 × 0.65) = 0.33169 ms, plus 27 layers × 0.055 ms = 1.48500 ms, so 1000 ÷ 1.81669 ms = ~550 tok/s
Estimated speed at Q4_K_M (10.2 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of DeepSeek v2 Lite Chat?
At Q4_K_M, the download is about 9.42 GB. The full-precision BF16 version is 31.41 GB. The smallest option (IQ2_XXS) is 4.32 GB.
Which GPUs can run DeepSeek v2 Lite Chat?
38 consumer GPUs can run DeepSeek v2 Lite Chat at Q4_K_M. Top options include AMD Radeon RX 6800, AMD Radeon RX 6800 XT, AMD Radeon RX 6900 XT, AMD Radeon RX 6700 XT. 26 GPUs have plenty of headroom for comfortable inference.
Which devices can run DeepSeek v2 Lite Chat?
150 devices with unified memory can run DeepSeek v2 Lite Chat at Q4_K_M (10.2 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
