enhanced capabilities in coding, computer use, long-context reasoning, agent planning, knowledge work, and design.<\/p>\n<p>The new model features a 1 million token context window in beta and is now the default for users on the Free and Pro plans in <strong>claude.ai<\/strong> and <strong>Claude Cowork<\/strong>, with pricing remaining consistent with Sonnet 4.5.<\/p>\n<p>Developers have shown a strong preference for Sonnet 4.6 over its predecessor, citing improvements in consistency and instruction following, with many even preferring it over the previous top-tier model, <strong>Claude Opus 4.5<\/strong>.<\/p>\n<p>Sonnet 4.6 demonstrates significant advancements in computer use, performing comparably to human-level capabilities in tasks like navigating complex spreadsheets and filling out multi-step web forms, as measured by the <strong>OSWorld<\/strong> benchmark.<\/p>\n<p>The model also shows improved resistance to prompt injection attacks, a critical safety consideration for AI that interacts with computer systems.<\/p>\n<p>In terms of coding, Sonnet 4.6 is preferred by users for its better context reading and consolidation of shared logic, leading to a less frustrating development experience.<\/p>\n<p>The expanded 1 million token context window allows Sonnet 4.6 to process entire codebases or extensive documents, enabling more effective long-horizon planning, as evidenced by its strategic performance in the <strong>Vending-Bench Arena<\/strong> simulation.<\/p>\n<p>Early customers have reported more polished visual outputs, better layouts, and improved design sensibility in frontend code and financial analysis generated by Sonnet 4.6, requiring fewer iterations to achieve production-quality results.<\/p>\n<p><strong>Databricks<\/strong>, <strong>Replit<\/strong>, <strong>Cursor<\/strong>, <strong>GitHub<\/strong>, <strong>Cognition<\/strong>, <strong>Windsurf<\/strong>, <strong>Hebbia<\/strong>, <strong>Box<\/strong>,
