anthropic released fable 5, a version of its mythos model, to the public via api and enterprise plans, offering capabilities in software engineering and vision. to mitigate risks associated with the model's power, anthropic implemented a mandatory 30-day retention policy on all traffic to monitor for jailbreaks and abuse, regardless of prior zero-retention contracts. the model blocks responses in high-risk areas like cybersecurity and biology, defaulting to opus 4.8 for safety, and is priced at $10 per million input tokens and $50 per million output tokens.
