192GB RAM
Calculated for 4-bit (Q4_K_M) @ 8K Context1. Select Quantization Level
Quantization compresses model weights to reduce RAM usage, with minor impacts on output quality.
2. Set Target Context Length
Longer contexts require more active memory for the Key-Value (KV) cache.

DeepSeek-V4-Flash (284B MoE) Memory FAQs
How much RAM does DeepSeek-V4-Flash (284B MoE) require?
To run DeepSeek-V4-Flash (284B MoE) locally, memory size depends on your selected quantization. At 4-bit compression (Q4_K_M), the weights take up ~159.8GB of RAM. When combined with context cache and OS overhead, a standard **192GB system memory kit** is recommended. Unquantized FP16 execution requires a **768GB memory setup**.
What are the hardware requirements to run DeepSeek-V4-Flash (284B MoE) at FP16 precision?
Running DeepSeek-V4-Flash (284B MoE) at unquantized 16-bit precision requires loading ~568GB of model weights directly into VRAM or system memory. A minimum system memory target of **768GB RAM** is required to run the weights stably and avoid out-of-memory crashes.
Is DeepSeek-V4-Flash (284B MoE) dense or Mixture-of-Experts (MoE)?
DeepSeek-V4-Flash (284B MoE) is built on a **MoE** architecture. It has a total of 284 Billion parameters, but only activates 13 Billion parameters per token. While active parameter sparse execution makes token computing very fast, the entire 284B parameters must reside in VRAM/RAM for fast expert switching during execution.
How does context window size affect RAM usage for DeepSeek-V4-Flash (284B MoE)?
Context size directly scales the size of the Key-Value (KV) cache. At a standard 8,192 token context, the KV cache for DeepSeek-V4-Flash (284B MoE) uses ~0.03GB. If you scale this to 1 Million tokens, the KV cache can scale past hundreds of GBs, requiring multi-GPU or workstation-class RAM configurations.
