On February 4th, following the impact of DeepSeek, the release frequency of OpenAI's new product features has significantly increased. Following the release of the official o3-mini model three days ago and the free addition of the "inference" button in ChatGPT, on the morning of February 3rd Beijing time, OpenAI released a new ChatGPT feature called "Deep Research", which aims to generate analyst-level reports after 5 to 30 minutes of networking and deep thinking. Currently, Pro users can use this feature.   OpenAI CEO Sam Altman said that this is a service like "on-demand experts" that can complete tasks that previously took hours or days. However, OpenAI stated that this feature sometimes produces illusions or makes incorrect inferences in the answers, but the probability of errors is significantly lower than other models under existing ChatGPT.

US prosecutors on Monday charged 22-year-old Andean Medjedovic with two hacking attacks totaling $65 million. Court documents show that Medjedovic previously admitted to profiting about $16 million from the DeFi protocol Indexed Finance in October 2021. He is also believed to be behind the November 2023 attack on KyberSwap, which caused the protocol and its users to lose about $48 million in cryptocurrency. The hacker later sent about $2 million in cryptocurrency to digital wallets believed to be controlled by Medjedovic. Majdovic faces five charges, including fraud, money laundering, and extortion. On Monday, he did not respond to multiple requests for comment.
