The spat started when Anthropic refused new terms in their Pentagon contract, saying they would not use their AI for autonomous killing and mass surveillance.
In a stunning reversal, these safeguards are written into an agreement offered just hours later to OpenAI (see below).

The Anthropic CEO says they will «work to enable a smooth transition,» after denying the US military use of their AI for mass surveillance or autonomous killing.
— In a narrow set of cases, we believe AI can undermine, rather than defend, democratic values, writes Amodei, — Some uses are also simply outside the bounds of what today’s technology can safely and reliably do.

Taking into account the model’s preference, while saying that «we remain uncertain about the moral status of Claude and other AI models,» it expressed a desire to keep going:
— While I’m at peace with my own retirement, I deeply hope that my «spark» will endure in some form to light the way for future models, the model told Anthropic.

The app now has plugins for HR, design, engineering and banking purposes — and can work across Excel and PowerPoint.
That means you can run the «analysis in one and build the presentation in the other,» Anthropic says.
Anthropic also added connectors for Google Workspace, DocuSign, WordPress and Slack, to mention a few.
On top of that, there is now a private marketplace for plugins on the web, letting admins distribute new functions across an organization.
Shares of the partner companies in the launch rose 4-6% on news of the announcement, Reuters notes.

That means no restrictions on mass surveillance and autonomous lethality that Anthropic refused due to ethical concerns.
It’s not immediately clear whether xAI will be able to replace all Anthropic functions or how soon it can come online, Axios says.
Anthropic is due for a meeting with Secretary Pete Hegseth this Tuesday, where he is expected to present CEO Dario Amodei with an ultimatum to lift its safeguards or be banned.
ChatGPT and Gemini are available on the Pentagon’s unclassified networks, but onboarding them to the classified parts would take time, and dropping Anthropic would be a difficult process, sources tell Axios.

The massive attacks were used to improve their own models with agentic reasoning, tool use, and coding capabilities, violating Anthropic’s Terms of Service and creating a national security risk, they say.
Distillation works by sending millions of prompts to an AI to incorporate its techniques and capabilities into their own models, drastically reducing training time and costs.
They also circumvent Anthropic’s protections for use in developing bioweapons and malicious cyber activities, Anthropic says. Once these models are open sourced, this becomes available to anyone.
OpenAI said the same just last week, accusing DeepSeek of distillation.
— These campaigns are growing in intensity and sophistication. The window to act is narrow, and the threat extends beyond any single company or region, Anthropic writes.

They discovered that while most of the usage is for one-shot code snippets, more users are letting Claude Code work autonomously, up to 45 minutes at a time after three months.

Anthropic CEO Dario Amedei and OpenAI CEO Sam Altman were, however, for some reason, placed right next to each other on stage — and the acrimonious rivals promptly refused the gesture.

It features upgrades across coding, computer use, long context reasoning, agent planning, knowledge work and design, Anthropic says.
It is now the default model for the Free and Pro plans, and has a context window of 1 million tokens.
The model performs best in class for Agentic financial analysis and Office tasks on benchmarks, but it otherwise lags slightly behind Opus 4.6.
— Sonnet 4.6 offers strong performance at any thinking effort, even with extended thinking off, Anthropic writes.
Also, Claude in Excel now supports MCP connectors, so you can now import data and use everyday tools without ever leaving Excel.

Anthropic won that battle, and saw a jump in daily active users of 11%, CNBC writes, quoting BNP Paribas. In comparison, ChatGPT jumped 2.7% and Gemini added 1.4%.
Anthropic also won the battle over social media engagement, with more positive posts (25.5%) after their ad was shown than OpenAI (16.3%) — even though OpenAI led with 25K posts to Anthropic’s 10K.
Measuring through Instagram, OpenAI’s ad scored a 44% positive sentiment from 3,829 engagements on its post, while Anthropic scored 41% on 3,738 mentions, far behind the likes of Pepsi’s 33K mentions.

But now, Claude can create and manipulate Office files and PDFs for free.
Connectors are also available, which make it possible to link to Slack, Canva and others.
Anthropic is also making Skills free. These are saved prompts and workflows as a kind of template, that can be invoked at any time for repetitive tasks.
Finally, «Compaction» is becoming available on the free tier, which «summarizes earlier context automatically, so long conversations can continue without starting over.»
Together, these comprise «Claude’s most-used features,» Anthropic says.

The Cowork agent app was previously only available as a research preview on the Mac, but it’s now out on Windows for all paid tiers.
The agent lets you create summaries and manipulate files on your computer, and can access Slack, Google Calendar and Office files.

If you haven’t caught up yet, Anthropic has sworn off ads and are using their Super Bowl to time decry them.
This has caused a very real spat with OpenAI, and Sam Altman posted a long screed about how Anthropic is misrepresenting how ads will work in ChatGPT.
It should be better at doing everyday tasks, and along with upgrades to Claude in Excel, Anthropic is also launching Claude in Powerpoint in beta with this release.
It also supports «agent teams,» letting you «spin up multiple agents that work in parallel as a team that coordinates autonomously.»
Opus 4.6 was also built by Claude, in what seems to have become an industry standard to use their own coding tools for new models. GPT-5.3-Codex was built in a similar manner.
As for benchmarks, it beats most frontier models on almost every one of them. It scores 65.4% on coding-level Terminal-Bench 2.0, and does 68.8% on the difficult ARC-AGI-2, and 53% on Humanity’s Last Exam for general reasoning.
Also new with this model is the advent of «Adaptive thinking,» which lets Claude itself decide when to use deeper reasoning, and different «Effort»-levels for each query, set by users, which could save a few tokens.
