Claude Fable 5.2 was launched by Anthropic on Monday as the Dario Amodei-led AI giant's latest AI model. The Fable series model was introduced along with Mythos 5.2, Anthropic's most advanced cybersecurity-focused AI model. The new Mythos model is available to select cybersecurity professionals via a verification programme. Both models are claimed to bring performance improvements on multiple fronts, including coding, reasoning, and vision. Anthropic says that both new Fable and Mythos models were found to communicate “more clearly” than their predecessors. Moreover, the two AI models are more affordable than Fable 5.1 and Mythos 5.1.
