Ethan Mollick on working with Mythos-class models
The Neuron ● Covered by 3 sources
Ethan Mollick tested Claude 5 Fable, Anthropic's new Mythos-class AI model, and found it substantially outperformed previous public models across diverse tasks from academic writing to software development. In one project, the model spent 9.5 hours building Concord, a research tool for calibrating human and AI judgments on datasets, using its own spawned agents to conduct research and verify code while making hundreds of autonomous decisions. The shift changes the user's role from actively steering the AI's work to commissioning finished outputs, with little visibility into the model's decision-making process, raising questions about whether increased capability inherently means decreased human control.
Why it matters
Ethan Mollick explored how Fable 5 changes the job from steering every step to commissioning a finished outcome, representing a fundamental shift in how AI assists with work.
