Introducing Claude Opus 4.6
The new Claude Opus 4.6 improves on its predecessor’s coding skills. It plans more carefully, sustains agentic tasks for longer, can operate more reliably in larger codebases, and has better code review and debugging skills to catch its own mistakes. And, in a first for our Opus-class models, Opus 4.6 features a 1M token context window in beta.
Opus 4.6 can also apply its improved abilities to a range of everyday work tasks: running financial analyses, doing research, and using and creating documents, spreadsheets, and presentations. Within Cowork, where Claude can multitask autonomously, Opus 4.6 can put all these skills to work on your behalf.
The AI that spooked the stock market just got a big update
Anthropic’s Cowork AI assistant sent shockwaves through Wall Street this week. Now Anthropic is taking another leap forward, improving its model.
Anthropic’s new Claude Opus 4.6 model, announced Thursday, is designed to make Cowork AI better for office and coding work, potentially raising even more concerns that the AI tool could replace specialized software packages that companies use for those tasks.
Legal and financial analysis software stocks have plunged in recent days, bringing the broader stock market down with them. The Nasdaq just had its worst two-day tumble since April, and it’s down another 0.7% Thursday.
Many experts wonder whether AI will ultimately cost some workers their jobs. Tech giants like Anthropic, OpenAI and Google are locked in a race to build AI models that they hope will underpin the future workplace.
