Anthropic on Thursday released
The launch comes just three days after OpenAI released its own
For the first time, Anthropic's Opus-class models will feature a 1 million token context window, allowing the AI to process and reason across vastly more information than previous versions. The company also introduced "agent teams" in Claude Code — a research preview feature that enables multiple AI agents to work simultaneously on different aspects of a coding project, coordinating autonomously.
"We're focused on building the most capable, reliable, and safe AI systems," an Anthropic spokesperson told VentureBeat about the announcements. "Opus 4.6 is even better at planning, helping solve the most complex coding tasks. And the new agent teams feature means users can split work across multiple agents — one on the frontend, one on the API, one on the migration — each owning its piece and coordinating directly with the others."
Why OpenAI and Anthropic are locked in an all-out war for enterprise developers
The release intensifies an already fierce competition between
coding assistants have exploded in popularity over the last year, and OpenAI said more than

Inside Claude Code's $1 billion revenue milestone and growing enterprise footprint
The stakes are substantial. Asked about Claude Code's financial performance, the Anthropic spokesperson noted that in November, the company announced that Claude Code
The spokesperson highlighted major enterprise deployments: "Claude Code is used by Uber across teams like software engineering, data science, finance, and trust and safety; wall-to-wall deployment across Salesforce's global engineering org; tens of thousands of devs at Accenture; and companies across industries like Spotify, Rakuten, Snowflake, Novo Nordisk, and Ramp."
That enterprise traction has translated into skyrocketing valuations. Earlier this month, Anthropic signed a term sheet for a
How Opus 4.6 solves the 'context rot' problem that has plagued AI models
One of Opus 4.6's most significant technical improvements addresses what the AI industry calls "
"This is a qualitative shift in how much context a model can actually use while maintaining peak performance," the company said in its announcement.
The model also supports outputs of up to 128,000 tokens — enough to complete substantial coding tasks or documents without breaking them into multiple requests.
For developers, Anthropic is introducing several new API features alongside the model: adaptive thinking, which allows Claude to decide when deeper reasoning would be helpful rather than requiring a binary on-off choice; four effort levels (low, medium, high, max) to control intelligence, speed and cost tradeoffs; and context compaction, a beta feature that automatically summarizes older context to enable longer-running tasks.
Anthropic's delicate balancing act: Building powerful AI agents without losing control
When asked how Anthropic thinks about safety guardrails as Claude becomes more agentic, particularly with multiple agents coordinating autonomously, the spokesperson pointed to the company's
The company said it has developed six new cybersecurity probes to detect potentially harmful uses of the model's enhanced capabilities, and is using Opus 4.6 to help find and patch vulnerabilities in open-source software as part of defensive cybersecurity efforts.
Sam Altman vs. Dario Amodei: The Super Bowl ad battle that exposed AI's deepest divisions
The rivalry between Anthropic and OpenAI has spilled into consumer marketing in dramatic fashion. Both companies will feature prominently during Sunday's Super Bowl. Anthropic is airing commercials that
OpenAI CEO Sam Altman responded by calling the ads "funny" but "
The exchange highlights a fundamental strategic divergence: OpenAI has moved to monetize its massive free user base through advertising, while Anthropic has focused almost exclusively on enterprise sales and premium subscriptions.

What Claude's new PowerPoint integration means for Microsoft's AI strategy
Among the more notable product announcements: Anthropic is releasing Claude in PowerPoint in research preview, allowing users to create presentations using the same AI capabilities that power Claude's document and spreadsheet work. The integration puts Claude directly inside a core Microsoft product — an unusual arrangement given Microsoft's 27% stake in OpenAI.
The Anthropic spokesperson framed the move pragmatically in an interview with VentureBeat: "Microsoft has an official add-in marketplace for Office products with multiple add-ins available to help people with slide creation and iteration. Any developer can build a plugin for Excel or PowerPoint. We're participating in that ecosystem to bring Claude into PowerPoint. This is about participating in the ecosystem and giving users the ability to work with the tools that they want, in the programs they want."
The data behind enterprise AI adoption: Who's winning and who's losing ground
Data from a16z's recent
The survey data also shows that 75% of Anthropic's enterprise customers are using it in production, with 89% either testing or in production — figures that slightly exceed OpenAI's 46% in production and 73% testing or in production rates among its customer base.
Enterprise spending on AI continues to accelerate. Average enterprise LLM spend reached $7 million in 2025, up 180% from $2.5 million in 2024, with projections suggesting $11.6 million in 2026 — a 65% increase year-over-year.
Pricing, availability, and what developers need to know about Claude Opus 4.6
Opus 4.6 is available immediately on claude.ai, the Claude API, and major cloud platforms. Developers can access it via claude-opus-4-6 through the API. Pricing remains unchanged at $5 per million input tokens and $25 per million output tokens, with premium pricing of $10/$37.50 for prompts exceeding 200,000 tokens using the 1 million token context window.
For users who find Opus 4.6 "overthinking" simpler tasks—a characteristic Anthropic acknowledges can add cost and latency—the company recommends adjusting the effort parameter from its default high setting to medium.
The recommendation captures something essential about where the AI industry now stands. These models have grown so capable that their creators must now teach customers how to make them think less. Whether that represents a breakthrough or a warning sign depends entirely on which side of the disruption you're standing on — and whether you remembered to sell your software stocks before Tuesday.
