AI Industry Splits Over Open Weights, Safety, and the Pace of Progress
In late July 2026, a series of open letters revealed a deep rift in the AI industry over open-weight models, regulation, and the pace of automated research. A coalition of 235 companies, led by Microsoft, argued for open weights, while Anthropic emphasized risks and called for targeted restrictions. Additionally, 1,324 employees from frontier AI labs urged international coordination to deliberately pace AI development, citing examples of rapid automation in coding and hardware design.
