What is DeepSeek? Full Guide to DeepSeek LLM & DeepSeek Code (2025)

🔍 Introduction

DeepSeek is a family of open-source large language models (LLMs) developed by DeepSeek AI, a research group focused on building competitive and transparent alternatives to proprietary models like GPT-4 and Gemini.

With DeepSeek-VL, DeepSeek-Coder, and DeepSeek-LLM, the organization has made waves in the AI open-source community, especially among developers looking for powerful models for coding, language, and vision tasks.

🏢 Who Created DeepSeek?

DeepSeek AI is a Chinese AI research lab and startup that launched in 2023. It quickly gained attention for:

  • Open-sourcing large transformer models

  • Competing with GPT-4 in coding and math

  • Focusing on multilingual and multimodal tasks

The lab is inspired by organizations like Hugging Face, Meta AI (LLaMA), and Mistral.

🚀 DeepSeek Model Family (2025)

Model Type Highlights
DeepSeek-LLM Language Model GPT-style general-purpose LLM
DeepSeek-Coder Code LLM Fine-tuned for software development
DeepSeek-VL Vision-Language Handles image + text inputs
DeepSeek-MoE Mixture-of-Experts Scalable & efficient expert routing

🧠 What is DeepSeek-LLM?

DeepSeek-LLM is a series of base and instruction-tuned models trained on trillions of tokens. Available in sizes from 1.3B to 67B parameters, it offers:

  • High-quality reasoning and generation

  • Open weights for research and commercial use

  • Performance close to or better than LLaMA 2

📦 Available on Hugging Face: deepseek-ai/deepseek-llm

💻 What is DeepSeek-Coder?

DeepSeek Coder is a specialized model for coding and software development, trained on a vast corpus of public GitHub repositories.

Features:

  • Supports 80+ programming languages

  • Handles complex software engineering tasks

  • Competitive with GPT-4 in code generation

Variants:

  • DeepSeek-Coder-1.3B

  • DeepSeek-Coder-6.7B

  • DeepSeek-Coder-Instruct

📦 Check: huggingface.co/deepseek-ai/deepseek-coder

🧠 What is DeepSeek-VL?

DeepSeek-VL (Vision Language) allows multimodal understanding—processing both text and images.

Use cases:

  • Document QA with diagrams

  • Image captioning

  • OCR + NLP pipelines

  • Visual Chatbots

It’s positioned as an open alternative to GPT-4-Vision and Gemini Pro Vision.

🧪 Benchmarks & Performance

DeepSeek models score highly on:

Benchmark Score Notes
MMLU Near GPT-4 Good general reasoning
HumanEval 71–82% Competitive coding
GSM8K High Strong in math
Multi-modal QA 80%+ VL model strength

⚙️ How to Use DeepSeek in Python

Using transformers:

python
from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline

model_id = "deepseek-ai/deepseek-coder-6.7b-instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
output = pipe("Write a Python function to sort a list.", max_new_tokens=100)

print(output[0]['generated_text'])
