Recently, Fu Sheng posted an article on the X platform to promote his AI Agent product "Thirty Thousand Lobsters". Fu Sheng said: "My 30,000 lobsters have been fully switched to DeepSeek V4 Pro. The physical feel is completely the same as Sonnet, and some tasks are even better. What about the price? Sonnet is 15 US dollars / million tokens, while DeepSeek V4 Pro is only 8 cents. It is 17 times different and there is no token anxiety at all."

Subsequently, on May 2, some netizens posted on social platforms questioning Fu Sheng, saying that his product "Lobster Thirty Thousand" used the code of the open source project NewApi for secondary development, but removed the copyright information, and did not mark the open source address on the page, which is suspected of violating the open source agreement obligations.
The netizen said: "Does the boss of a company not even understand the open source protocol? I took the second version of the NewApi project code and removed the copyright information. I searched the page for a long time and couldn't find your open source address. I didn't even come to us to regulate it. Avoid source obligations?”

Another netizen commented: “It’s a big company after all, so let your subordinates use new The api stuff is fooling you.”
Fu Sheng replied: “Am I that stupid?”
It is reported that “Lobster Thirty Thousand” is an AI Agent product launched by Fu Sheng, which has recently been announced to be connected to DeepSeek-V4 Pro. DeepSeek-V4 was released on April 24, 2026, and is divided into two versions: Pro and Flash.
NewApi is an open source project on GitHub. It is positioned as an AI large model aggregation gateway and is based on the secondary development of One API. Its core function is to uniformly convert large model APIs from different vendors such as OpenAI, Claude, Gemini, and DeepSeek into a standard OpenAI compatible format. The project is open source under the MIT license, allowing free use, modification and commercial use, but the copyright statement and original license are required to be retained. The project has received nearly 20,000 stars on GitHub.
Currently, Fu Sheng and Cheetah Mobile have not officially responded to the specific accusation of “removing copyright information”.
