The analysis covers benchmark results across SWE-bench, HumanEval, and LiveCodeBench, comparing Opus 5 against Sonnet 4, GPT-4.1, and Gemini 2.5 Pro. Key findings: Opus 5 earns its premium on complex bug detection, security audits, multi-file refactoring, and agentic workflows, but Sonnet 4 delivers 90-95% of the quality for routine code generation and documentation at one-fifth the cost. The 200K context window is a structural disadvantage versus GPT-4.1 and Gemini 2.5 Pro's 1M windows. Practical Python benchmark scripts are included for measuring latency, token usage, and cost across models in your own stack. The recommended strategy is model routing: Opus 5 for hard problems, Sonnet 4 for routine tasks, Haiku for high-volume low-complexity work. ## 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 cost per million tokens compared to Sonnet 4 and GPT-4.1? Claude Opus 5 costs $15 per million input tokens and $75 per million output tokens, the same pricing as Opus 4. That is 5x Sonnet 4's input rate of $3/$15 per million tokens and 7.5x GPT-4.1's input rate of $2/$8 per million tokens. Gemini 2.5 Pro is cheaper still at $1.25/$10 per million tokens for prompts up to 200K tokens. _Teams weighing model costs before scaling AI coding workflows can track pricing shifts like this on daily.dev._ ### Should I use Claude Opus 5 or Sonnet 4 for routine code generation tasks? Sonnet 4 is the better choice for routine code generation and documentation, delivering 90% or more of Opus 5's output quality at one-fifth the cost. Opus 5's premium is best justified for complex architectural decisions, security-sensitive code review, and multi-file agentic workflows where higher first-attempt correctness reduces costly iteration cycles. _daily.dev helps developers deciding between AI models keep up with cost-performance tradeoffs like this one._ ### Why is Claude Opus 5 slower than Sonnet 4 for coding tasks? Opus 5's time-to-first-token runs roughly 2-4x higher than Sonnet 4 due to its larger size and computational requirements, and enabling extended thinking mode increases latency further as the model generates internal reasoning tokens before responding. This makes it a poor fit for real-time coding assistants like autocomplete, though it matters less for asynchronous CI/CD or batch code review workflows. _Developers picking models for latency-sensitive coding tools can follow tradeoffs like these on daily.dev._ ## Similar posts on daily.dev - [Claude Opus 4.8 Pricing 2026: Everything you need to know](https://daily.dev/posts/claude-opus-4-8-pricing-2026-everything-you-need-to-know-mdtq6vqrl) · finout · 41 upvotes · 4 comments --- Tags: [#ai](https://daily.dev/tags/ai), [#python](https://daily.dev/tags/python), [#ai-coding](https://daily.dev/tags/ai-coding), [#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-performance-benchmarks-for-developers-apj6zcfvz) ```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: Performance Benchmarks for Developers","url":"https://daily.dev/posts/claude-opus-5-performance-benchmarks-for-developers-apj6zcfvz","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/claude-opus-5-performance-benchmarks-for-developers-apj6zcfvz"},"datePublished":"2026-08-11T00:17:05.363Z","dateModified":"2026-09-14T09:31:53.545Z","description":"Claude Opus 5 launched on July 17, 2025, priced at $15/$75 per million input/output tokens — identical to Opus 4 but with improved reasoning and coding...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/10811e6f4e8eb8a010c7478a98b8a3fb?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/10811e6f4e8eb8a010c7478a98b8a3fb?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"SitePoint","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":"SitePoint","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/sitepoint","url":"https://daily.dev/sources/sitepoint"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/claude-opus-5-performance-benchmarks-for-developers-apj6zcfvz","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai,python,ai-coding,claude,anthropic","timeRequired":"PT19M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"SitePoint","item":"https://daily.dev/sources/sitepoint"},{"@type":"ListItem","position":3,"name":"Claude Opus 5: Performance Benchmarks for Developers"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/claude-opus-5-performance-benchmarks-for-developers-apj6zcfvz#faq","mainEntity":[{"@type":"Question","name":"How much does Claude Opus 5 cost per million tokens compared to Sonnet 4 and GPT-4.1?","acceptedAnswer":{"@type":"Answer","text":"Claude Opus 5 costs $15 per million input tokens and $75 per million output tokens, the same pricing as Opus 4.
