Anthropic transformed the AI landscape with the launch of Claude Opus 4.6—a significant advancement for its premier AI model and a daring step in the continuous competition with OpenAI. The release, which was introduced in GitHub Copilot and on Anthropic’s own platforms, occurs at a time when the stakes for enterprise AI are at their peak, and the competition is more intense than ever.

Claude Opus 4.6 is more than just a typical minor update. As reported by VentureBeat, Anthropic’s newest model boasts an impressive 1 million token context window, enabling the AI to handle and analyze significantly more information than all earlier versions.

This indicates that developers can provide Opus 4.6 large quantities of code, documentation, or data—and the model can monitor everything, sustaining optimal performance without the unfortunate “context rot” that has affected previous systems.

Anthropic claims that Opus 4.6 achieved a score of 76percent on the MRCR v2 benchmark, a challenging test for long-context retrieval, while its earlier version, Sonnet 4.5, only attained 18.5percent.

However, that isn't everything. The update also unveils “agent teams” in Claude Code—a research preview capability that enables several AI agents to collaborate on various facets of a coding project at the same time, working independently.

An Anthropic representative informed VentureBeat that "Opus 4.6 is improved in planning, facilitating the resolution of the most intricate coding challenges." The new agent teams function allows users to distribute tasks among various agents—one handling the frontend, another focusing on the API, and a third on migration—each responsible for their segment and collaborating directly with the rest.

For business users, these enhancements are not merely technical feats—they're delivering genuine business outcomes. As per Anthropic, Claude Code achieved a run rate revenue of $1 billion only six months following its general release in May 2025.

Prominent firms such as Uber, Salesforce, Accenture, Spotify, Rakuten, Snowflake, Novo Nordisk, and Ramp have embraced the technology for various applications ranging from software engineering to finance and trust and safety. This swift momentum has led to soaring valuations: earlier this month, Anthropic finalized a term sheet for a $10 billion funding round at a $350 billion valuation, according to reports.
