What it feels like to work with Mythos

Claude Fable, Anthropic's new Mythos-class AI model, represents a significant leap in AI capabilities, consistently outperforming all previous public models across diverse tasks from academic papers to interactive games and complex data visualization projects. The author found the experience both delightful and unnerving—while the model executes requests with impressive sophistication (including multi-hour projects and creative outputs without external assets), the ease and autonomy with which it accomplishes tasks raises questions about humanity's changing relationship with AI. Beyond raw performance benchmarks, Fable demonstrates a fundamental shift in how users interact with AI systems, moving from simple queries to delegating complex, multi-step problem-solving processes.
