Anthropic has introduced<\/a> its new AI model, Claude Sonnet 4.5, showcasing advanced capabilities in programming. According to the company, it can create “production-ready” applications.<\/p>\n

\n

“This is the most consistent frontier model we have ever released, with significant improvements in many aspects compared to previous versions of Claude,” the blog states.<\/p>\n<\/blockquote>\n

Over the past year, Anthropic’s solutions have become favorites for tackling software development tasks. According to media reports<\/a>, companies like Apple and Meta are using Claude models internally.<\/p>\n

The startup claims that Claude Sonnet 4.5 demonstrates industry-leading performance in several programming benchmarks such as SWE-Bench Verified.<\/p>\n

The model can autonomously write code for up to 30 hours straight. During such a test, it not only created an application but also deployed database services, registered domain names, and conducted an audit according to the SOC 2<\/span> standard.<\/p>\n

Alongside the launch of Claude Sonnet 4.5, Anthropic introduced the Claude Agent SDK, an infrastructure for creating agents.<\/p>\n

Other updates include:<\/p>\n

    \n
  • Claude Code now features checkpoints, allowing progress to be saved and reverted to previous states;<\/li>\n
  • the Claude API<\/span> now includes tools for contextual editing and memory, enabling agents to work longer and handle greater complexity;<\/li>\n
  • Claude applications now integrate code execution and file creation directly within dialogues;<\/li>\n
  • the Claude extension for Chrome is now available to Max users.<\/li>\n<\/ul>\n

    The company demonstrated how the extension<\/a> allows Claude to operate directly in the browser: navigating websites, filling out spreadsheets, and completing tasks.<\/p>\n
