In a not-so-surprising turn of events, Microsoft is reportedly limiting the use of Claude Fable 5 because of Anthropic's new data retention requirements. It's part of Anthropic's Mythos class of models and ships with powerful capabilities across software engineering and analytics.
Following the new data retention requirements, Anthropic can now retain prompts and outputs generated for up to 30 days. It's also worth noting that content flagged by its safety systems can be retained for up to 2 years to facilitate ample time for investigation or enforcement.
