Anthropic released Claude Fable 5.2 and Mythos 5.2 yesterday, which the company says can take on more ambitious technical work, including projects that require coordinating other agents over extended periods.
Fable and Mythos share the same underlying model. Fable has stronger safeguards around cybersecurity and biology. Organizations seeking Mythos for those applications must qualify through Anthropic’s verification programs.
The standard API price is $8 per million input tokens and $40 per million output tokens, down from $10 and $50 for the previous versions. Your actual project cost will also include the number of attempts, the work delegated to other models, and the people needed to verify the result.
There is also a data decision. The models ordinarily require 30-day retention for safety monitoring, with exceptions requiring Anthropic’s authorization. Enterprise Frontier Safeguards, now in private beta, allows monitoring of prompts and responses stored in a customer’s own infrastructure. Eligible customers can use zero data retention while transitioning to that arrangement.
The quality of the work these models do is likely to have an outsized impact on everyone’s “nice to have” list. Using the new models, Anthropic says a team of agents migrated a critical production service from Python to Rust. The company reports that the service now starts about 26 times faster. (This was the expected result.) However, this vendor-reported result points to a good question: Which projects have you postponed (or simply could not consider) because the engineering work was too expensive to justify?
Every company needs a Claw strategy. Do you have one?
