DeepSeek R1 Distill Qwen 14B GPU requirements: 7.39 GB at 4-bit, 29.5 GB at BF16
DeepSeek R1 Distill Qwen 14B needs 29.5 GB of GPU memory for its weights at BF16, 14.8 GB at FP8 and 7.39 GB at 4-bit, plus 6.44 GB of KV cache for a 32K context. The cheapest node that runs it here is 1× RTX A4000 at 4-bit, for $0.03 an hour on spot.
Weights plus a 32K 16-bit KV cache, with 10% of the node's memory kept free. Billed per minute.

How much VRAM DeepSeek R1 Distill Qwen 14B needs, format by format.
Weights are parameters × bytes per parameter. Each context column adds the KV cache of one sequence of that length.

The serving engine adds its own buffers, and an 8-bit KV cache halves the context columns. We keep 10% of a node's memory free when we say a model fits. Speed is a separate question: it follows memory bandwidth and, for a mixture of experts, the active parameters.

Serving several users
KV cacheEvery concurrent request keeps its own cache, so memory for context grows with users × context length. A server batching 8 requests of 32K needs eight times the single-sequence figure — 51.5 GB here.

- Weights at 4-bit7.39 GB
- Context that fits, 1 sequence35K
Paged attention (vLLM, SGLang) allocates the cache in blocks as requests grow, so a node holds more short requests than the worst case suggests.

DeepSeek R1 Distill Qwen 14B on a GPU — the questions that come up
How much VRAM does DeepSeek R1 Distill Qwen 14B need?
For the weights alone: 29.5 GB at BF16, 14.8 GB at FP8 and 7.39 GB at 4-bit. Add 6.44 GB of KV cache for one 32K-token context, or 25.8 GB at the full 128K window, and keep about 10% of the memory free for activations.
Can DeepSeek R1 Distill Qwen 14B run on a single GPU?
One RTX 4090 (24 GB): yes, at FP8. One RTX 5090 (32 GB): yes, at FP8. One H100 SXM (80 GB): yes, at BF16. One H200 SXM (141 GB): yes, at BF16. One B200 SXM (180 GB): yes, at BF16. Those answers assume a 32K context and the widest format that still fits.
What is the cheapest way to run DeepSeek R1 Distill Qwen 14B?
Here, 1× RTX A4000 at 4-bit: $0.03 per hour on spot and $0.05 on-demand, billed per minute — $21.90 for a 730-hour month on spot. That node has 16 GB of GPU memory for the 13.8 GB this setup needs.
How long a context fits on the recommended node?
With the weights at 4-bit on 1× RTX A4000, the remaining memory holds a 16-bit KV cache for about 35,680 tokens of context for one sequence (35K). An 8-bit KV cache doubles that; serving several users at once divides it between them.
Which format should I run it in?
BF16 keeps the published weights untouched and is the format for fine-tuning. FP8 halves the memory and runs in hardware on Hopper, Ada, Blackwell and MI300-class GPUs. 4-bit quantisation (AWQ, GPTQ, GGUF) quarters it, at a quality cost that is larger on small models than on big ones; check it against your own evaluation before relying on it.
How do I deploy it?
Pick the node in the table above and launch it with the vLLM template; the model downloads from Hugging Face (deepseek-ai/DeepSeek-R1-Distill-Qwen-14B) on first start. Spread the weights over the node with --tensor-parallel-size equal to the GPU count, and set --max-model-len to the context you need. New architectures need a recent vLLM: check the model card for the minimum version.
