Anthropic has released an upgraded version of its artificial intelligence model, launching Claude Opus 4.6.

The latest version "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," the company said in a statement Thursday.

The model now includes a one‑million‑token context window in beta and applies its improved capabilities across everyday tasks such as financial analysis, research, and creating or working with documents, spreadsheets, and presentations.

"Claude Opus 4.6 is the strongest model Anthropic has shipped. It takes complicated requests and actually follows through, breaking them into concrete steps, executing and producing polished work even when the task is ambitious. For Notion users, it feels less like a tool and more like a capable collaborator," said Sarah Sachs, AI Lead at Notion.

‘More Focus, Better Judgment’

The software is available today on all major cloud platforms. The upgraded version of Opus is "much better" at retrieving relevant information from large sets of documents, according to the release.

"We've found that the model brings more focus to the most challenging parts of a task without being told to, moves quickly through the more straightforward parts, handles ambiguous problems with better judgment, and stays productive over longer sessions," the company said.

The model introduces adaptive thinking, where it can pick up on contextual clues about how much to use its extended thinking, as well as new effort controls to give developers more control over intelligence.

The model has also made "substantial upgrades" to Claude in Exel, and is releasing Claude in PowerPoint in a research preview for Max, Team and Enterprise plans.

More Safeguards

Anthropic also developed safeguards within Opus 4.6, adding six more cybersecurity probes — methods of detecting harmful responses to help them track different forms of potential misuse.

"We think it's critical that cyberdefenders use AI models like Claude to help level the playing field. Cybersecurity moves fast, and we'll be adjusting and updating our safeguards as we learn more about potential threats; in the near future, we may institute real-time intervention to block abuse," the company said.

Benzinga reported on Monday that internal forecasts for Anthropic point to $18 billion in revenue by 2026 and a path to $50 billion-plus by 2027 — implying a nearly 180% jump in a single year.

Anthropic is embedding Claude into corporate tech stacks — across platforms like ServiceNow and deployments at JPMorgan — where contracts are long-term and measured in eight- or nine-figure commitments.
