While DeepSeek can point to common benchmark results and Chatbot Arena leaderboard to prove the competitiveness of its model, there's nothing like direct use cases to get a feel for just how useful a new model is.

OpenAI thinks DeepSeek may have used its AI outputs inappropriately, highlighting ongoing disputes over copyright, fair use, and training data.

DeepSeek is a Chinese artificial intelligence provider that develops open-source LLMs. R1, the latest addition to the company’s model lineup, debuted last week. The release of the LLM caused a broad selloff in AI stocks that sent Nvidia Corp.’s shares plummeting 17% on Monday, along with many other technology stocks.
