Summary

Companies are accelerating moves to open-source and sovereign AI after Anthropic’s June 30-day chat-retention mandate for Fable and Mythos raises privacy concerns, prompting Booz Allen to restrict Fable use before new zero-data-retention options arrive Sept. 1.

Key Points

  • Companies increasingly adopt open-source models and sovereign AI to keep control of sensitive data and reduce reliance on OpenAI and Anthropic.
  • Anthropic's June 30-day chat-retention mandate for its Fable and Mythos models prompts companies including Booz Allen to restrict use of Fable.
  • OpenAI introduces Private Safety Processing on Aug. 19, and Anthropic follows Sept. 1 with zero-data-retention options that let customers store data in their own cloud accounts.
