Question 1

How much VRAM does DeepSeek-V2-Lite-Chat need?

Accepted Answer

DeepSeek-V2-Lite-Chat (15.7B) requires approximately 35.10672798156738 GB of VRAM at full precision (FP16), 17.6 GB at 8-bit quantization (Q8), and 8.8 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run DeepSeek-V2-Lite-Chat?

Accepted Answer

We have 10 compatible GPUs indexed for DeepSeek-V2-Lite-Chat, including A40, L40S, A100 40GB, L40, A100 80GB PCIe and 5 more. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run DeepSeek-V2-Lite-Chat?

Accepted Answer

The cheapest GPU to run DeepSeek-V2-Lite-Chat in the cloud is the A40 at $0.44/hr. Other affordable options include L40S ($0.60/hr) and A100 40GB ($0.93/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can DeepSeek-V2-Lite-Chat run on consumer hardware?

Accepted Answer

DeepSeek-V2-Lite-Chat may be able to run on high-end consumer GPUs like the RTX 4090 (24 GB) with 4-bit quantization (Q4), which reduces VRAM usage to approximately 8.8 GB. However, performance may be limited compared to datacenter GPUs.

Question 5

What quantization options are available for DeepSeek-V2-Lite-Chat?

Accepted Answer

DeepSeek-V2-Lite-Chat supports the following quantization levels: FP16 (full precision): ~35.10672798156738 GB, Q8 (8-bit): ~17.6 GB, Q6 (6-bit): ~13.2 GB, Q4 (4-bit): ~8.8 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression. As a Mixture of Experts (MoE) model with 64 experts (6 active), DeepSeek-V2-Lite-Chat has a larger total weight size but only activates a subset of parameters per token, which can affect effective memory usage during inference.
