Orange AI on X: "Today, Claude Fable 5 officially launched, built on the Mythos foundation but with added safety guardrails. Fable 5 represents the most significant model advancement since Claude 4.5. It is currently the best model available for widespread human use. You can give this model more ambitious large tasks, and it will understand and execute them perfectly, without you needing to look at any code.

Today, Claude Fable 5 officially launched, built on the Mythos foundation but with added safety guardrails. Fable 5 represents the most significant model advancement since Claude 4.5. It is currently the best model available for widespread human use. You can give this model more ambitious large tasks, and it will understand and execute them perfectly, without you needing to look at any code. Andrej Kapathy, who recently joined A Corp, commented as follows:
Fable 5's model metrics are, as expected, strong. In almost all tested AI capability benchmarks, it ranks at the top, demonstrating excellent performance in various fields such as software engineering, knowledge work, visual recognition, and scientific research. The more complex and time-consuming the task, the more significant Fable 5's lead over other models becomes. In terms of pricing, Fable 5 is naturally the most expensive. The input price is $10, the output price is $50, and the cached input price is $1. In the case of long text, a single sentence can cost $10, so everyone should set up their quotas and use it sparingly. Claude Fable 5 will be launched at its original price on Cola for everyone to experience.
