Anthropic released two new models on Monday, Claude Fable 5.2 and Claude Mythos 5.2, which it described as its most advanced offerings. The company said the models generate outputs 30 percent faster than their predecessors and cost 20 percent less than the 5.1 generation, at 8 dollars per million input tokens and 40 dollars per million output tokens. Fable 5.2 is generally available from Monday, while Mythos 5.2 is limited to vetted organizations through Anthropic’s Life Sciences and Cyber Verification Programs, the restricted route the company has used for Mythos since April because of its cybersecurity capabilities.
Dianne Penn, Anthropic’s head of product management for research, told CNBC the models are aimed at complex, open-ended technical work in engineering, mathematics and robotics, and said of the company’s September slowdown call, “We called for pacing, not pausing.” The release comes as Anthropic prepares an initial public offering that CNBC reported could take place as soon as next week, at a target valuation of 1 trillion to 1.5 trillion dollars, down from 2 trillion dollars floated in recent months; its amended prospectus put revenue for the nine months to September 30 at 33.24 billion dollars, up roughly 1,200 percent from a year earlier.
