DeepSeek, a Chinese AI startup founded in 2023 by Lian Wenfeng, has gained significant attention in the AI community with its open-source language model, DeepSeek R1, which offers competitive performance at a fraction of the cost compared to models from OpenAI and Meta. The model excels in reasoning tasks and utilizes Reinforcement Learning (RL) as its primary training strategy, distinguishing itself from models that rely on Supervised Fine-Tuning. DeepSeek R1 is evaluated favorably against other models in benchmarks like AIME 2024 for mathematics, Codeforces for coding, and MMUL for general knowledge. The startup also provides distilled versions of its models in various sizes, making them accessible for personal use on standard hardware. A detailed guide explains how to set up and run DeepSeek on an AWS EC2 instance using Infrastructure as Code (IaC) with Pulumi, allowing users to experiment with the model's capabilities and integrate it into applications via an OpenAI-compatible API.
