Users can sign up for email or SMS notifications to follow updates on the incident. ## Content Claude Opus 5 launched recently, but the rollout hasn't been smooth. Anthropic's status page is tracking elevated errors on the model, with email and SMS notifications available for updates. Beyond the technical issues, at least some users are reporting stranger behavior: the model apparently loops through tasks multiple times without completing them. One user described moving back to Opus 4.8 after concluding Opus 5 felt designed to burn through tokens rather than finish work. It's early days, and launch-day instability isn't unusual. Whether the looping complaints reflect a real regression or just rough first impressions during a buggy rollout remains to be seen. --- Tags: [#llm](https://daily.dev/tags/llm), [#claude](https://daily.dev/tags/claude), [#anthropic](https://daily.dev/tags/anthropic) [View this post on daily.dev](https://daily.dev/posts/claude-opus-5-launches-with-early-errors-da4xcmkmk) ```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":"TechArticle","headline":"Claude Opus 5 launches with early errors","url":"https://daily.dev/posts/claude-opus-5-launches-with-early-errors-da4xcmkmk","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/claude-opus-5-launches-with-early-errors-da4xcmkmk"},"datePublished":"2026-07-27T12:32:19.162Z","dateModified":"2026-07-27T19:08:02.085Z","description":"Anthropic has launched Claude Opus 5, announced by Alex Albert.
