DeepSeek R1 Online

Need to work through a tricky math problem, debug a function, or draft code without creating an account? DeepSeek R1 Online gives you browser access to the DeepSeek R1 reasoning model, and the free tier needs no login.

It is an AI chatbot and code generator built around an open-source large language model, so the same model family is also available for developers who want to work with it directly.

DeepSeek R1 uses a Mixture of Experts architecture and reinforcement learning, and it is aimed at mathematics, coding, general reasoning and multilingual understanding.

The site also offers distilled versions of the model for different use cases, which is handy when you want something lighter than the full model.

The listing also covers translation and education uses, plus image generation and editing.

Pricing is free, which makes DeepSeek R1 Online an easy place to test the model before building anything on it.
