DeepSeek Open-Source AI Model Deployment & Usage Guide
Top-tier open-source AI from China — DeepSeek-V3 has 101K+ GitHub Stars, 671B parameters (37B activated), MIT License. Rivals GPT-4o and Claude Sonnet 3.5 at 1/18th the API cost. Free web chat, API access, and full local deployment.
DeepSeek Deployment & Usage Guide
Three ways: Free web chat / API calls / Local deployment
Option 1: Free Web Chat (Zero Barrier)
Visit chat.deepseek.com for free access to DeepSeek-V3 and R1. Supports DeepThink mode, web search, file upload, voice input. iOS/Android app available. 131M+ monthly active users, #1 in App Store across 157 countries.
Option 2: API Access (For Developers)
Register at platform.deepseek.com for an API Key. 5M free tokens for new users. OpenAI-compatible format — just change base_url and api_key. V3.2 input costs only $0.27/M tokens.
Option 3A: Ollama Local Deploy (Easiest)
Install Ollama (ollama.com), run ollama pull deepseek-r1 to download. Distilled models from 1.5B to 70B. Pair with Open WebUI for ChatGPT-style interface. Fully offline, data stays local.
Option 3B: vLLM Deploy (Production)
Enterprise-grade. pip install vllm, download weights from Hugging Face, tensor parallelism across multiple GPUs. FP8 and BF16 precision. For NVIDIA H100/H200 clusters.
Option 3C: SGLang Deploy (Officially Recommended)
DeepSeek's recommended framework with MLA optimizations, DP Attention, FP8 KV Cache, Torch Compile. Supports both NVIDIA and AMD GPUs. Best latency and throughput.

Based on GitHub repos and official technical reports
MoE Architecture
671B total parameters, only 37B activated per token. MLA + DeepSeekMoE architecture delivers far superior inference efficiency vs dense models of similar scale.
DeepThink Reasoning
DeepSeek-R1 trained via pure RL (no SFT needed), with self-verification and reflection. Rivals OpenAI o1 on math, code, and reasoning benchmarks.
Code Generation
HumanEval 82.6% Pass@1, LiveCodeBench 40.5%, Codeforces 51.6 percentile. Comprehensively leads all open-source models in coding tasks.
Extreme Value
API input just $0.27/M tokens (V3.2), 18.5x cheaper than GPT-5. Context Caching cuts costs by 90% more. 5M free tokens for new users.
MIT Open Source
Code under MIT license, model weights support commercial use. Full weights on Hugging Face. 32 public repos, 86K+ followers.
Rich Distilled Models
6 distilled versions (1.5B to 70B) based on Llama and Qwen. 32B version outperforms OpenAI o1-mini. Small models run locally via Ollama.
Multi-Framework Deploy
Official support for SGLang (recommended), vLLM, LMDeploy, TensorRT-LLM, LightLLM. Compatible with NVIDIA, AMD GPUs, and Huawei Ascend NPUs.
OpenAI Compatible API
Fully OpenAI-compatible: streaming, function calling, JSON mode, vision. Switch from GPT by changing base_url to https://api.deepseek.com.
