Anthropic has launched Claude Opus 5, positioning it as a cost-effective alternative to the heavily restricted Fable 5 model. The new release delivers performance comparable to its competitor while reportedly costing half the price. Benchmarks indicate that while Fable 5 retains slight advantages in specific areas, Claude Opus 5 outperforms in business workflows, computer use, and agentic research. It also achieves state-of-the-art results in several coding and knowledge work evaluations. Anthropic emphasizes that Opus 5 requires less effort to succeed in complex tasks compared to other models running at high effort. The model maintains costs similar to the previous Opus 4.8 version. Unlike Fable 5, which carries heavier restrictions, Opus 5 is expected to intervene significantly less often during operations. Although Fable 5 remains superior in cybersecurity exploitation and biology, Opus 5 offers a more capable solution for the broader user base. The model is now available across all platforms, marking a strategic shift toward accessible, high-performance AI without the premium price tag associated with top-tier competitors.
