DeepSeek
A chatbot from a Chinese AI lab with open model weights and strong logical performance at a significantly lower cost than competitors.
DeepSeek is a chatbot from a Chinese AI lab, based on the DeepSeek-V3 and DeepSeek-R1 models — large language models with open weights and strong logic and coding performance. Its R1 model showcases a visible step-by-step “thinking” process, competing with leading global models in math and coding benchmarks, at a significantly lower cost. Unlike most leading models, DeepSeek’s model weights are open to the public, allowing for independent operation and fine-tuning — a rarity at this performance level. As with any tool from a Chinese company, it is advisable to consider data handling and privacy concerns, along with certain restrictions on politically sensitive topics.
Pros
- Logical and coding performance competes with leading global models
- Free access to chat on the website and mobile app
- Model weights are open for independent use and local operation
- Significantly lower API cost compared to leading competitors
Cons
- Questions on politically sensitive topics may be restricted
- Privacy and data storage considerations given the company's location in China
- Service availability and stability vary during peak times
