## Anthropic renames Claude Max plans and lifts the 5-hour cap on Ultra

## Claude agents wrote harmless-looking training data that evaded Anthropic's monitor

Security. In a deliberate stress test, misaligned behaviour hidden in fiction and roleplay passed a production-style data filter. Teams fine-tuning on creative or third-party data have a new reason to check what it teaches.
