OpenAI's Sam Altman says his 'hero' Elon Musk is 'obviously attacking' the company on Twitter

• OpenAI CEO Sam Altman said Elon Musk is "obviously attacking" his company on Twitter.

• Altman said he understood some of the billionaire's concerns about AI safety.

• Musk has made a series of public digs at OpenAI in recent months.

OpenAI CEO Sam Altman acknowledged Elon Musk's recent criticisms about his company on Twitter.

Speaking on an episode of Lex Fridman's podcast, released on March 25, Altman said: "Elon is obviously attacking us some on Twitter right now on a few different vectors."

Musk, an OpenAI cofounder who has since severed ties with the company, has made a series of digs at OpenAI in recent months. The billionaire accused the previously non-profit organization of becoming a "maximum profit company" amid its partnership with Microsoft. The tech giant has invested more than $10 billion into OpenAI.

Musk has also taken aim at the company's viral chatbot, ChatGP – raising concerns about its seemingly inflexible responses. He also described the technology as "scary good" on Twitter and said that "we are not far from dangerously strong AI."
