Dario Amodei, CEO of Anthropic, has publicly diverged from OpenAI and other major tech companies regarding open AI models. While acknowledging some points in a recent open letter, Amodei disagrees that broad access to open weights enhances safety, highlighting Anthropic's view of risks associated with open-source AI and their non-open model business strategy.
“And Anthropic is the one major AI company that's yet to endorse the letter. Yesterday, CEO Dario Amodei published a response.”
“He wrote that he agrees with many of the points in the open letter, but disagrees that broad access to open weights makes the ecosystem safer.”
“They've made clear, they see risks with open source. And from a competitive standpoint, they don't have open models and they're pretty against them.”
