ZDNETAnthropic’s Claude AI now has a new model able to “think” longer and deeper when crafting a response to your request. Also: 10 key reasons AI went mainstream overnight – and what happens nextKnown as Claude 3.7 Sonnet, this latest model uses advanced reasoning and greater processor time to evaluate your question in a step-by-step process and then produce a detailed result. The new model doesn’t come freeThe new extended thinking mode is accessible through the Claude website and the API for developers. But it doesn’t come free. Even though Claude 3.7 Sonnet is available for all users, you must have a Pro or Team subscription to tap into the extended thinking option. The extended mode is particularly adept at tackling difficult math and coding problems, as well as front-end web development, Anthropic said in an announcement on Monday. In this mode, Claude “self-reflects” before it provides an answer. Taking the time to develop its response helps it better handle tasks that involve math, physics, instruction-following, and coding. Along the way, Claude shows you the steps it took to arrive at its solution. Also: From zero to millions? How regular people are cashing in on AIIn its announcement, Anthropic also touted the performance of Claude 3.7 Sonnet in early testing and use. One site found the new model significantly improved at handling complex codebases and using advanced tools. Another successfully used Claude to build sophisticated web apps and dashboards from scratch — a task that challenged other models. In a third evaluation, Claude created production-ready code with quality designs and dramatically fewer errors. It’s better than OpenAI’s o1?Testing of agentic tools put Claude 3.7 Sonnet ahead of the 3.5/3.6 version of Sonnet and OpenAI’s o1 model. Testing in software engineering placed Claude 3.7 Sonnet at the top among the previous version, OpenAI’s o1, and DeepSeek R1.Also: 3 easy side hustles OpenAI’s Operator just made possible – plus how you can get started”We’ve developed Claude 3.7 Sonnet with a different philosophy from other reasoning models on the market,” Anthropic said in its announcement. “Just as humans use a single brain for both quick responses and deep reflection, we believe reasoning should be an integrated capability of frontier models rather than a separate model entirely. This unified approach also creates a more seamless experience for users.” More
