Who it's for
- Students who need step-by-step reasoning for math or logic problems and want it free. You can turn on reasoning mode at no cost
- Developers who want to download the open weights and run them on a company server or their own PC
- People who find ChatGPT's free limits tight and want a second chatbot in reserve
Drawbacks
- Check how your data is handled first. Conversation data from the web service is stored on servers in China, and some countries and institutions restrict its use. It's safer not to enter personal or company material
- On certain topics, such as Chinese politics, it avoids answering or gives biased answers
- When traffic is heavy, responses slow down or you see a "server busy" notice
Getting started
- Sign up on the official site with an email address or a Google account.
- Write your question, and for hard problems turn on the "DeepThink" (reasoning) button before sending. The thinking process appears first.
- Turn on the "Search" button when you need current information.
- If Chinese or English slips in, add "answer in Korean only".
- Don't enter company material or personal information. If you need to, run the open model in a local execution tool.
