In my opinion, this brings the top spot in LLM selection back to Fable, since GPT still has an old version. You can find out more about the new version, as well as much more, on their official website: [https://www.anthropic.com/claude-fable-and-mythos-5-1](https://www.anthropic.com/claude-fable-and-mythos-5-1) ## Community discussion Top comments from developers on daily.dev. **@agustinbarrientos** · 1 upvotes > Which benchmark and evaluation setup produced the order-of-magnitude claim? --- Tags: [#llm](https://daily.dev/tags/llm), [#claude](https://daily.dev/tags/claude), [#anthropic](https://daily.dev/tags/anthropic), [#gpt](https://daily.dev/tags/gpt) [View this post on daily.dev](https://daily.dev/posts/the-new-version-of-fable-5-1-has-been-released-4yljvsjru) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/the-new-version-of-fable-5-1-has-been-released-4yljvsjru","headline":"The new version of Fable 5.1 has been released","text":"Anthropic reportedly released Claude Fable 5.1, claimed to outperform GPT 5.6 by an order of magnitude in benchmarks, with a link to Anthropic's website for more details and the author's opinion that this puts Fable back on top of LLM rankings.","url":"https://daily.dev/posts/the-new-version-of-fable-5-1-has-been-released-4yljvsjru","datePublished":"2026-09-02T16:17:15.001Z","dateModified":"2026-09-02T16:17:30.602Z","author":{"@type":"Person","name":"Anthony Max","url":"https://daily.dev/aanthonymax","image":"https://media.daily.dev/image/upload/s--IOCG5ocV--/f_auto/v1745861623/avatars/avatar_lfRKMBQjVJU9aG1HuqtVg","description":"Fetch API enjoyer","interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"EndorseAction"},"userInteractionCount":1160}},"image":"https://media.daily.dev/image/upload/s--sf48TLoi--/f_auto/v1788365835/posts/4YLJvSjrU?_a=BAMAMicg0","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":3},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":3}],"comment":[{"@type":"Comment","text":"Which benchmark and evaluation setup produced the order-of-magnitude claim?","datePublished":"2026-09-03T21:41:57.280Z","url":"https://daily.dev/posts/4YLJvSjrU#c-JS3hd3ypA","author":{"@type":"Person","name":"Agustin Barrientos","url":"https://daily.dev/agustinbarrientos","image":"https://media.daily.dev/image/upload/s--5ayxQnqn--/f_auto/v1788281802/avatars/avatar_wQYYVe5Tbj0NJ7C7qPoa8?_a=BAMAMicg0"},"interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1}}],"isPartOf":{"@type":"WebPage","url":"https://daily.dev/sources/lfrkmbqjvju9ag1huqtvg","name":"Anthony Max"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Anthony Max","item":"https://daily.dev/sources/lfrkmbqjvju9ag1huqtvg"},{"@type":"ListItem","position":3,"name":"The new version of Fable 5.1 has been released"}]} ```
