Output tokens now cost $20 per million versus $25 for the prior version, with other pricing metrics dropping similarly and the model running faster due to lower compute needs. The release also tweaks Opus's communication style to reduce jargon and front-load key information. It arrives two months after Opus 5, with Sonnet 5.5 and Haiku 5.5 expected soon. Because its biology and cybersecurity capabilities match Mythos, Opus 5.5 is subject to the same safety safeguards. The release is also Anthropic's first since CEO Dario Amodei publicly committed to deliberately pacing capability advances to let safety work keep up. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How much does Claude Opus 5.5 cost compared to Opus 5? Opus 5.5 output tokens cost $20 per million tokens, down from $25 per million for the prior Opus 5 model. Other pricing metrics dropped by similar margins, and the new model also runs faster due to a reduction in the compute required to serve it. _Track Claude pricing changes like this on daily.dev before they hit your API bill._ ### When was Claude Opus 5.5 released and how does it compare to Opus 5? Opus 5.5 was released on a Tuesday, about two months after Opus 5 shipped on July 24th. Anthropic says it sets a new state-of-the-art in coding and knowledge work, outpacing the larger Fable model on many benchmarks and completing informal tasks Fable failed at, while also being cheaper and faster to run. _Compare model releases like this on daily.dev when deciding which Claude version to build on._ ### What is Dario Amodei's plan to pace AI capability advancement at Anthropic? Dario Amodei committed to deliberately slowing the rate of AI capability progress so that alignment and risk-prevention work has time to catch up, describing this in a post as 'pacing the frontier.' Opus 5.5 is the first Anthropic model released since that commitment, though its safety training remained broadly similar to earlier models. _Follow AI safety commitments like this on daily.dev to gauge how they shape future model releases._ --- Tags: [#llm](https://daily.dev/tags/llm), [#claude](https://daily.dev/tags/claude), [#anthropic](https://daily.dev/tags/anthropic), [#ai-safety](https://daily.dev/tags/ai-safety) [View this post on daily.dev](https://daily.dev/posts/anthropic-releases-opus-5-5-with-lower-prices-and-fable-level-performance-3xn8k74hd) ```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":"Anthropic releases Opus 5.5 with lower prices and Fable-level performance","url":"https://daily.dev/posts/anthropic-releases-opus-5-5-with-lower-prices-and-fable-level-performance-3xn8k74hd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/anthropic-releases-opus-5-5-with-lower-prices-and-fable-level-performance-3xn8k74hd"},"datePublished":"2026-09-22T16:30:49.610Z","dateModified":"2026-09-22T17:11:27.567Z","description":"Anthropic released Opus 5.5, claiming it sets a new state of the art in coding and knowledge work performance and outperforms the larger Fable model on many...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/eceea8f5fc03d5772cbe285349ff8db8?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/eceea8f5fc03d5772cbe285349ff8db8?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"TechCrunch","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"TechCrunch","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tc","url":"https://daily.dev/sources/tc"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/anthropic-releases-opus-5-5-with-lower-prices-and-fable-level-performance-3xn8k74hd","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"llm,claude,anthropic,ai-safety","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"TechCrunch","item":"https://daily.dev/sources/tc"},{"@type":"ListItem","position":3,"name":"Anthropic releases Opus 5.5 with lower prices and Fable-level performance"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/anthropic-releases-opus-5-5-with-lower-prices-and-fable-level-performance-3xn8k74hd#faq","mainEntity":[{"@type":"Question","name":"How much does Claude Opus 5.5 cost compared to Opus 5?","acceptedAnswer":{"@type":"Answer","text":"Opus 5.5 output tokens cost $20 per million tokens, down from $25 per million for the prior Opus 5 model.
