OpenAI and Anthropic keep warning about a future they're building at breakneck speed
- Anthropic and OpenAI are publicly warning that AI is advancing “lightning fast” and urging international coordination or slowdowns so regulation and safety can catch up.
- Both just launched flagship models (Anthropic’s Claude Fable 5 and OpenAI’s GPT‑5.5) and are pushing adoption through developer tools and guardrails.
- Both companies are also preparing for IPOs (confidential S‑1 filings), adding a business/market dimension to the safety debate.
