Anthropic has partnered with the U.S. Department of Energy's National Laboratories to participate in the first-ever 1,000 Scientist AI Jam event. This session will bring together scientists from multiple laboratories to evaluate the capabilities of Claude 3.7 Sonnet, a hybrid reasoning model, on scientific research and national security applications. The AI Jam represents a significant milestone in Anthropic's partnership with DOE National Laboratories, building on previous collaborations such as the evaluation of Claude in a Top Secret classified environment by NNSA and DOE National Laboratories. This event aims to harness AI's transformative potential while addressing potential risks through rigorous testing, ultimately contributing to accelerating American scientific leadership and progress in solving humanity's greatest challenges.
