Opus 5 outperforms Fable 5 in business workflows, computer use, and agentic research, and is expected to intervene 85% less often than Fable 5, which carries heavier restrictions.", "body_md": "Anthropic says its Claude Opus 5 AI model is an improvement that takes less effort to deliver similar results as the nearly-banned Fable 5.\n\nClaude Opus 5 is [available now](https://www.anthropic.com/news/claude-opus-5) as the next version of what used to be Anthropic’s highest performer. When Fable 5 was [released](https://9to5google.com/2026/06/09/anthropic-claude-mythos-fable-5-model-release/), recalled, then [released again](https://9to5google.com/2026/07/01/anthropic-fable-5-returns-to-claude/), it sat above Opus 4.8 in terms of pure performance.\n\nThe margins have shifted slightly. Claude Opus 5 reportedly costs half the price of Fable 5, yet it delivers results that are similar in performance. Benchmarks released by Anthropic detail the disparity. It looks like Fable 5 is slightly better in a few areas, but the difference is narrow. In areas like business workflows, computer use, and agentic research, Claude Opus 5 performs better.\n\nFable 5 is famously a token-monster, too. Anthropic says it improved the Opus model, all while keeping the costs similar to what users were used to with Opus 4.8. Anthropic also notes that even when Opus 5 runs at minimal effort, it still succeeds in more tasks than other models at high effort when working through business workflows.\n\nFable 5 is currently available to users, but it carries heavier restrictions. The new Opus 5 release, though, is expected to intervene around 85% less often. Fable 5 is still king in terms of highly advanced tasks in cybersecurity exploitation and biology, but Opus 5 is expected to present a much more capable model to the broader user base.\n\nOpus 5 is available on all platforms starting today.\n\n*FTC: We use income earning auto affiliate links.* [More.](https://9to5mac.com/about/#affiliate)\n\n[our homepage](http://9to5google.com/)for all the latest news, and follow 9to5Google on\n\n[exclusive stories](https://9to5google.com/feature/exclusive/),\n\n[reviews](https://9to5google.com/guides/reviews/),\n\n[how-tos](https://9to5google.com/guides/how-to/), and\n\n[subscribe to our YouTube channel](https://www.youtube.com/9to5google)", "url": "https://wpnews.pro/news/claude-opus-5-launches-with-similar-performance-as-fable-5-for-half-the-price", "canonical_source": "https://9to5google.com/2026/07/24/anthropic-launches-claude-opus-5/", "published_at": "2026-07-24 18:34:50+00:00", "updated_at": "2026-07-26 13:07:22.404752+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-startups"], "entities": ["Anthropic", "Claude Opus 5", "Fable 5", "Opus 4.8"], "alternates": {"html": "https://wpnews.pro/news/claude-opus-5-launches-with-similar-performance-as-fable-5-for-half-the-price", "markdown": "https://wpnews.pro/news/claude-opus-5-launches-with-similar-performance-as-fable-5-for-half-the-price.md", "text": "https://wpnews.pro/news/claude-opus-5-launches-with-similar-performance-as-fable-5-for-half-the-price.txt", "jsonld": "https://wpnews.pro/news/claude-opus-5-launches-with-similar-performance-as-fable-5-for-half-the-price.jsonld"}}
