AI model families: DeepSeek and the China AI scene

Understand DeepSeek and why China's AI models surprised the world.

40 min · Reviewed 2026

The big idea

DeepSeek is a Chinese AI lab that released models rivaling OpenAI's at a fraction of the cost. It shocked the industry. Their R1 reasoning model is open and very good at math and code.

Some examples

Try DeepSeek's chat for free
Use DeepSeek R1 for hard math
Notice the 'thinking' tokens DeepSeek shows
Compare DeepSeek to GPT-5 on logic

Try it!

Try DeepSeek's free chat. Give it a hard math problem and watch the reasoning trace. Notice how it 'thinks out loud' before answering.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

Ask AI to explain reasoning models in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "AI model families: DeepSeek and the China AI scene" and ask for two possible next steps plus one reason each step might be wrong.
Check deepseek against a trusted source, teacher, adult, expert, or original document before you use it.
