Exa Enterprise AI Launches Latest Model 'Claude Fable 5' on 'exaBase Generative AI' Platform

Exa Enterprise AI, a group company of ExaWizards Inc., has begun offering 'Claude Fable 5'—released by Anthropic on June 9 (U.S. time)—within its enterprise generative AI service, 'exaBase Generative AI'. The service allows secure access to this high-performance model by utilizing the same infrastructure as the 'Claude Mythos Preview' announced in April, while incorporating specialized safety guardrails.

## Features of Claude Fable 5

This model is characterized by its high capabilities in code generation, image recognition, and the ability to work on complex tasks over extended periods, achieving top-tier results in nearly all benchmark tests.

Furthermore, while using the same foundation as the Claude Mythos Preview, safety guardrails have been implemented. If the AI detects requests with high risk of misuse—such as in cybersecurity or biochemistry—the previous flagship model, Claude Opus 4.8, automatically takes over the response.
