Anthropic has just announced Claude Opus 4.6, the latest version of the high-end AI model line, with significant upgrades in programming, inference and complex task processing.
According to the company, Claude Opus 4.6 surpasses OpenAI's GPT-5.2 in many important standards, especially in the fields of programming, finance and multidisciplinary reasoning.
The most prominent feature of Claude Opus 4.6 is the first introduction of a context window of up to 1 million tokens in the beta version.
This allows the model to memorize and process huge volumes of text in one response, from long documents, entire books to large-scale software projects.
In essence, this is like equipping AI with a huge working memory, helping to improve the ability to analyze, reason and synthesize information.
In addition to superior context capacity, Claude Opus 4.6 is also significantly improved in terms of factor programming capabilities.
The model can plan more carefully, maintain automated tasks for longer, and operate stably in large code bases.
Anthropic said the new version also enhances the ability to review code, debug and self-detect errors in the programming process, a significant step forward for software engineers and technology businesses.
In terms of practical application, Claude Opus 4.6 is designed to support many daily tasks such as financial analysis, research, document processing, spreadsheets and presentations.
In the Claude Cowork environment (Claude Cowork is the work environment for Anthropic's AI), where chatbots can operate semi-automatically, the model can coordinate multiple skills to perform complex workflows, from data collection to aggregated reporting.
Performance evaluation results show Claude Opus 4.6 achieved the highest score in Terminal-Bench 2.0, which is an agent encoding capability test.
The model also leads in the Humanity’s Last Exam, a highly complex multi-disciplinary reasoning test.
In the fields of finance, law and online information search, Claude Opus 4.6 continues to surpass OpenAI's GPT-5.2 as well as its predecessor Opus 4.5.
In terms of safety and security, Anthropic emphasizes that Claude Opus 4.6 has a low misconduct rate, rarely encounters unnecessary rejection and is integrated with new cybersecurity measures.
The company also implements risk assessment mechanisms to check both defense capabilities and exploited potential.
Currently, Claude Opus 4.6 is ready via Anthropic's API, Claude.ai and major integration platforms, including Claude Code with the "agent group" feature for parallel source code evaluation, Cowork Environment for multi-step automation, and Office Suite.
The launch of Claude Opus 4-6 takes place in the context of an increasingly fierce global AI race, with OpenAI, Google and Anthropic continuously launching stronger models.
Earlier this week, Anthropic's product updates even caused strong fluctuations in the stock market, showing the sensitivity of the global economy to technological advances.
Under the leadership of Dario Amodei, Anthropic is expanding from its programming strengths to the fields of finance, law and healthcare, which are industries with great economic value.
The ultimate goal of AI laboratories is still general artificial intelligence (AGI), a system capable of performing most of human intellectual work.
