Anthropic released the Claude 4.5 AI model, stating the newest version can code for longer uninterrupted stretches as well as can maintain finance and scientific tasks better, as the startup pushes deeper into enterprise AI.
The AI startup backed by Alphabet and Amazon is competing with rivals to develop models that can reliably operate software and perform complex, multi-step tasks—key capabilities for AI agents that handle tasks on behalf of humans.
Claude 4.5 is stronger at finance and scientific reasoning and better at using computers, scoring about 60% on a benchmark that tests operating-system dexterity versus roughly 40% for prior models.
Anthropic, founded by former OpenAI executives, has held Claude for workplace use with guardrails it says reduce risky outputs. The company has been marketing Claude's coding as well as data-analysis skills to regulated industries and teams that want models to work across multiple software tools.
Executive Statement
According to Chief Product Officer Mike Krieger, the Sonnet 4.5 model created a web app from scratch in internal tests, and one customer had the AI chatbot code autonomously for 30 hours, up from a seven-hour run achieved by Anthropic's earlier Claude Opus 4 for a different client. Anthropic is targeting power users and business customers rather than chasing a viral consumer moment.
According to Chief Science Officer Jared Kaplan, It's a lot more visceral when you just see the model using a computer the way a person does if you're not a coder.
