What is DeepSeek? A Complete Overview
DeepSeek is an advanced, open-source AI platform that delivers high-performing language models and generative capabilities for diverse applications. It offers both developers and enterprises a flexible, scalable way to deploy large language models locally.
DeepSeek is a model provider, not a framework or orchestration tool.
How Does DeepSeek Work?
DeepSeek operates by using state-of-the-art transformer models trained on massive datasets to understand and generate human-like text. You can easily use, tweak, and connect these models through APIs, chat tools, or other apps for everyday tasks like coding and writing content.
Typical workflow:
- The interface captures and transmits the user's prompt for processing.
- DeepSeek’s LLM engine processes the input using advanced reasoning and context.
- The model generates a response, which is sent back to the user in real time.
- Optional: Responses and interactions can be logged, analyzed, or used to further train custom models.
System Requirements
Review the hardware specifications below to ensure your infrastructure is properly sized before beginning installation.
- Do not purchase a server that only meets minimum survival specs: Running with only baseline specifications (4 GB RAM, 5 GB Disk, and No GPU / CPU-only) represents the software's bare survival threshold and does not account for operating system overhead (~500 MB idle usage) or Ollama runtime (~150 MB). This can cause severe performance slowdowns, system freezes, or crashes during traffic spikes.
- Bluehost VPS/VDS & GPU Offloading: Bluehost Self-Managed VPS and VDS lack dedicated GPUs (VRAM). While CPU-only mode is supported, running local LLMs without an NVIDIA (CUDA) or AMD (ROCm) GPU results in significantly slower response times. For low-latency production workloads, use a GPU-equipped server or connect your application via API to an external cloud AI provider (like OpenAI or Anthropic).
- Node Resource Baselines: For a stable deployment, we recommend at least 4 vCPUs, 8 GB RAM (for the default model), and 20 GB+ Disk space. Allocate extra storage if you plan to save recordings, logs, or additional application data.
- Model Storage & Memory Scaling: Recommended RAM requirements per model:
- deepseek-r1:1.5b: 8 GB Recommended RAM
- deepseek-r1:7b: 16 GB Recommended RAM
- deepseek-r1:14b: 24 GB Recommended RAM
- deepseek-r1:32b: 64 GB Recommended RAM
- deepseek-r1:70b: 72 GB Recommended RAM
- Memory Error Warning: The default model pre-loaded on first boot is
deepseek-r1:1.5b. Pulling a larger model on a node with insufficient RAM will cause Ollama to return a500 Internal Server Error.
Hosting Options for High-Resource Needs
If your application requires more performance, you can choose between a Self-Managed VPS or a Virtual Dedicated Server (VDS).
Main Benefits of a VDS Server:
- Guaranteed Resources: You get 100% of your CPU, RAM, and storage. Other users cannot slow down your server.
- Better Security: Your server is completely isolated from others, keeping your data safer.
The following node resources outline the baseline hardware needed to run the system smoothly.
Node resources
Ensure your server meets or exceeds these baseline memory, storage, and processing specifications.
| Resource | Minimum | Recommended |
|---|---|---|
| RAM | 4 GB | 8 GB (default model); see model table below for larger models |
| Disk | 5 GB | 20 GB+ (if pulling multiple or larger models) |
| GPU | None (CPU-only supported) | NVIDIA (CUDA) or AMD (ROCm) GPU for faster inference |
Depending on which model you plan to deploy, system memory requirements will scale accordingly.
RAM requirements by model
Refer to the breakdown below to determine the exact RAM required for your selected model size.
RAM figures account for model weights (Q4_K_M quantization), KV cache at default context length, Ollama runtime (~150 MB), and Ubuntu OS idle usage (~500 MB).
| Model | Disk size | Min node RAM | Recommended RAM |
|---|---|---|---|
| deepseek-r1:1.5b | ~1.1 GB | 4 GB | 8 GB |
| deepseek-r1:7b | ~4.7 GB | 8 GB | 16 GB |
| deepseek-r1:14b | ~9.0 GB | 16 GB | 24 GB |
| deepseek-r1:32b | ~20 GB | 32 GB | 64GB |
| deepseek-r1:70b | ~43 GB | 64 GB | 72 GB |
The default model pre-loaded on first boot is deepseek-r1:1.5b. Pulling a larger model on a node with insufficient RAM will cause Ollama to return a 500 Internal Server Error.
Technical and Economic Advantages
- Performance: DeepSeek’s optimized transformer architecture delivers fast inference and high accuracy, even with large-scale models.
- Scalability: Easily scale deployments from single-user setups to enterprise clusters, thanks to modular design and container support.
- Cost Efficiency: Open-source means you aren't locked into one vendor, cutting down your bills. Plus, hosting it yourself means zero pricey API fees.
- Customization: Users can fine-tune models, integrate custom datasets, and adapt DeepSeek to specific business needs.
- Privacy & Security: Keep sensitive data entirely within your own infrastructure for ultimate security, and to ensure strict compliance.
Potential Challenges
- Resource Requirements: Huge models need heavy hardware infrastructure, especially for real-time tasks.
- Technical Expertise: The first setup and configuration may require familiarity with AI frameworks, Linux, and containerization.
- Maintenance: Regular updates, security patches, and model retraining are necessary to keep DeepSeek running optimally.
- Integration Complexity: Connecting DeepSeek to existing workflows or third-party tools may require custom development.
Core Advantages (Why DeepSeek Over Competitors?)
- Open-Source Flexibility: No licensing fees, full access to source code, and the ability to modify or extend functionality.
- Local & Cloud Deployment: DeepSeek can be run on-premises or in the cloud, offering flexibility for different environments.
- Active Community: Rapid development, frequent updates, and a wealth of shared resources from contributors worldwide.
- Privacy & Compliance: Ideal for organizations with strict data governance requirements, as all data can remain in-house.
- Customizability: Fine-tune models, add plugins, and tailor DeepSeek to unique business or research needs.
Note: DeepSeek is not a framework or orchestration tool. It is a model provider and does not support integration with various LLMs or AI frameworks.
