Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
Its capabilities exceed those of any model we’ve ever made generally available.
Fable 5 is state-of-the-art on nearly all tested benchmarks, with exceptional performance in software engineering, knowledge work, scientific research, and vision.
The longer and more complex the task, the larger Fable 5’s lead over our other models.
The productivity of working 1 minute every 30 minutes for 16 hours (i.e. 32 minutes) steering agents is much greater than working 8 hours a day (i.e. 480 minutes)
For complex projects, maybe.
People with high intelligence can easily figure it out still.
The playing ground is almost level, developers and engineers just have the edge.
