Claude Fable 5 Is Back: Anthropic's Most Powerful Model Returns

Claude Fable 5, Anthropic's advanced AI model, became available again on July 1, 2026, after a temporary suspension due to a US export-control directive. Initially released on June 9, 2026, it was quickly disabled on June 12, but resumed service following the directive's lift on June 30. The model, designed for complex tasks such as software engineering and deep research, outperforms its predecessors, scoring 80.3% on SWE-Bench Pro compared to GPT-5.5's 58.6%. Notably, Fable 5 is priced higher than previous models, costing $10 per million input tokens and $50 per million output tokens, making it suitable for tasks where precision is critical. Users can access it through Eden AI, which simplifies integration by allowing seamless switching between models like Claude Opus 4.8, ensuring continuity even if Fable 5 becomes unavailable or encounters issues. The model is intended for specialized use rather than everyday tasks, where cheaper alternatives may be more cost-effective.
