DeepSeek is a Chinese AI lab producing highly competitive open-source models. DeepSeek-V2 and DeepSeek-R1 match or exceed GPT-4 on many benchmarks at a fraction of the inference cost. DeepSeek Coder is particularly strong for programming tasks.

Why is DeepSeek significant?

DeepSeek demonstrated that state-of-the-art LLMs can be trained at a fraction of the cost previously assumed. Their MoE (Mixture of Experts) architecture and training innovations challenged the "scaling is all you need" narrative and made frontier-quality AI more accessible.

Can I use DeepSeek models commercially?

DeepSeek models are released under permissive open-source licenses allowing commercial use. You can download them from Hugging Face, run via Ollama, or access via API. Check the specific license for each model version.

DeepSeek-R1 is a reasoning model that matches OpenAI o1 on benchmarks while being open-weight. It uses chain-of-thought reasoning for complex math, coding, and logic problems. The training used GRPO (Group Relative Policy Optimization) for efficient RL.

How do I run DeepSeek locally?

Use Ollama: `ollama run deepseek-coder` or `ollama run deepseek-v2`. Alternatively, use vLLM or llama.cpp. The 7B Coder model runs on 8GB VRAM. Larger models (67B+) need more powerful hardware or quantization.

Is DeepSeek Coder good for programming?

DeepSeek Coder is among the best open-source coding models. It performs competitively with GPT-4 on coding benchmarks, supports many languages, and runs locally. Popular for code completion, generation, and explanation tasks.

How does DeepSeek achieve low inference costs?

DeepSeek uses MoE (Mixture of Experts) architecture where only a subset of parameters activate per token. This dramatically reduces compute costs while maintaining quality. Their efficient training methods also reduce the cost to train new models.
