Summary
Anthropic is releasing its first Mythos-tier model, Fable 5, to the general public, despite initial concerns about its potential dangers. The model has been deemed too powerful for public release due to its ability to find cybersecurity weaknesses. However, Anthropic says it has implemented new safety guardrails to prevent misuse. The model will be available for $10 per million input tokens and $50 per million output tokens, twice the price of the standard version of the next most advanced model.
Our Reading
The numbers tell one story. Anthropic’s decision to release Fable 5 comes just over a week after the company confidentially filed for IPO paperwork. The model’s capabilities exceed those of every model previously made generally available, with exceptional performance in areas such as coding, knowledge work, and vision. However, the company has faced backlash from users who claim that its safety filters occasionally “over-block” benign requests.
Anthropic’s confidence in its new guardrails is a signal.
