DeepSeek

DeepSeek is a Chinese-developed AI chat and language model created by DeepSeek, founded by Liang Wenfeng, and designed to compete with leading models like OpenAI’s ChatGPT. Launched in January 2025, it offers two main models: DeepSeek-V3 and DeepSeek-R1 , with the latter employing a “Test-Time Compute” (TTC) process to iteratively refine answers for improved accuracy and depth.

Key features include affordability, with free general chat use and low-cost API services ($0.55 per million input tokens and $2.19 per million output tokens), real-time web search integration, and robust coding support via its “DeepSeek Coder” feature. Accessible on iOS, Android, and the web, DeepSeek provides a user-friendly interface for both casual and professional users.

While it delivers state-of-the-art performance, fast inference speeds, and broad accessibility, it has limitations such as a lack of advanced functionalities like voice interaction or image generation.
