San francisco: US artificial intelligence company Anthropic on Tuesday announced the release of Claude Fable 5, the first public version derived from its powerful Claude Mythos model. 'Fable 5's capabilities exceed those of any model we've ever made generally available,' Anthropic said in a statement.

According to Anadolu Agency, the company stated that the model achieved state-of-the-art results across a range of benchmarks, including software engineering, scientific research, vision, and knowledge-based tasks. 'The longer and more complex the task, the larger Fable 5's lead over our other models,' it added.

Anthropic emphasized that Fable 5 includes safeguards designed to prevent misuse, such as efforts to exploit cybersecurity vulnerabilities or develop biological weapons. The original Mythos model was not released publicly due to concerns about its advanced cybersecurity capabilities, including its reported ability to identify vulnerabilities in critical infrastructure and software systems.

Anthropic had made Mythos available only to a limited group of companies, organizations, and government institutions. The company also announced the launch of Claude Mythos 5, a version with fewer restrictions that will be available to selected organizations. 'For a small group of cyberdefenders and infrastructure providers, we're also launching Claude Mythos 5. It has the strongest cybersecurity capabilities of any model in the world,' Anthropic said.

The company noted that models such as Fable 5 and Mythos 5 have the potential to strengthen cybersecurity by helping organizations identify and address vulnerabilities in critical software systems.
