Anthropic, valued at $965 billion and preparing an IPO, posted a June 5, 2026 blog urging a worldwide pause on advanced AI.
The firm said over 80 % of May’s code came from Claude, with engineers shipping eight times more code per quarter than before 2025.
Critics say the safety appeal may boost Anthropic’s image ahead of its IPO, while OpenAI says democratic governments, not private firms, should set AI rules.

OpenAI’s GPT-2 model, built on a 40 GB token dataset, marked an early stage of large-scale language models.

The swift launch reflects intensifying global competition in the LLM industry.
