Claude Model Cranks Out 11,000-Line Slack Clone in Record-Breaking 30-Hour Marathon

Anthropic's Claude Model Sets New Record with 30-Hour Marathon to Create Slack Clone In a groundbreaking achievement, Anthropic's Claude Sonnet 4.5 model has successfully completed a 30-hour autonomous run, generating approximately 11,000 lines of code for a chat application similar to Slack or Teams. This milestone marks a significant leap from the company's previous Opus 4 model, which ran for seven hours in May. According to Anthropic, Claude Sonnet 4.5 performs three times better than its October technology in browser navigation and computer use. Beta-tester Canva has already deployed the model for complex engineering tasks in its codebase and product features. "We're thrilled with the results of Claude Sonnet 4.5," said a spokesperson for Anthropic. "This model demonstrates our commitment to pushing the boundaries of AI capabilities and providing developers with powerful tools to build their own AI agents." The release of Claude Sonnet 4.5 comes with a suite of supporting tools, including virtual machines, memory, context management, and multi-agent support. These building blocks enable developers to create their own AI agents using the same technology that powers Claude Code. Anthropic's achievement is significant in the field of artificial intelligence, where models are increasingly being used for complex tasks such as code generation and automation. The company's focus on creating more efficient and effective AI tools has far-reaching implications for industries such as software development, engineering, and beyond. Experts in the field have welcomed Anthropic's breakthrough, noting its potential to revolutionize the way developers work. "This is a major step forward in the development of AI-powered code generation," said Dr. Rachel Kim, a leading researcher in AI and computer science. "Anthropic's Claude Sonnet 4.5 model has the potential to significantly reduce the time and effort required for complex coding tasks." As Anthropic continues to refine its technology, developers are eagerly anticipating the next developments in AI-powered code generation. With the release of Claude Sonnet 4.5, Anthropic is poised to take a leading role in shaping the future of artificial intelligence. In related news, Anthropic has announced plans to make Claude Sonnet 4.5 available for public testing and development in the coming months. This will provide developers with an opportunity to explore the capabilities of the model firsthand and contribute to its ongoing improvement. Anthropic's Claude Sonnet 4.5 model is a testament to the company's commitment to innovation and collaboration in the field of artificial intelligence. As the technology continues to evolve, one thing is clear: Anthropic is at the forefront of a new era in AI development. *Reporting by Developers.*
