Anthropic just moved into the office. Today it launched Claude Sheets and Claude Whiteboards in beta for every paid plan, made Claude Data generally available, and showed off Claude Meetings, an agent that joins your Google Meet calls and works while you talk.

It lands days before Anthropic's expected stock market debut, and it's aimed squarely at the tools Microsoft and Google sell to nearly every office.

Also tonight: Google opens Gemini 4 Carbon to every paying developer (at a price that doubles in three weeks), Meituan drops the weights for a 1.6-trillion-parameter open model, and four tools worth trying.

Claude Sheets and Claude Whiteboards are live in beta today on all paid Claude plans, on web, desktop and mobile. Sheets builds and edits real spreadsheets with tabs, formulas, formatting and dropdowns, often from a single prompt, and outlines every change it makes so your team can follow along. Whiteboards turns a messy plan into a shared board with a timeline, owners and dates, groups everyone's notes by theme, and can convert the finished board into a doc or deck.

Claude Dashboards also graduates to general availability under a new name, Claude Data. It connects to warehouses like BigQuery, Redshift and ClickHouse and turns your numbers into dashboards, written data stories or narrated videos. The headline-grabber is Claude Meetings: Claude joins a Google Meet call as a visible participant, drafts the plan while people are still talking, and leaves notes and action items in Claude afterward. TechCrunch reports it's in beta for Team and Enterprise customers, while Anthropic's own overview still calls it "coming soon," so expect a staged rollout.

Our take: Sheets is the one to try first. Anthropic itself says it's simple for now and points power users to Excel export or Claude for Excel, so don't plan to migrate your finance model. Where it shines is the zero-to-first-draft step: a hiring budget, a campaign tracker or a launch plan built from one prompt and then edited together. The bigger idea is shared context, since an idea can move from a whiteboard to a spreadsheet without re-explaining it. On Team plans all three are on by default; Enterprise admins have to switch Sheets and Whiteboards on.

Spreadsheets, whiteboards and meeting notes are the daily bread of Microsoft 365 and Google Workspace. Anthropic now sells all three inside Claude, backed by a marketplace of more than 9,000 connectors and plugins, and partner apps like Adobe, Atlassian, Box and Notion can now open right inside the chat. OpenAI made its own push into workplace tools a few weeks ago, TechCrunch notes, so the office is now a fight between the AI labs and the incumbents they run on.

The timing isn't subtle. Anthropic is aiming to go public as soon as the week of November 16, with AFP reporting a raise of up to $100 billion at a valuation above $1 trillion, down from earlier talk of $2 trillion (via Malay Mail). Its filings show $33 billion in revenue from January to September, per Gizmodo. Products that turn Claude from a chatbot into the place a team's work actually lives are exactly the recurring-revenue story investors want to hear. Reported IPO figures have shifted all month, so treat them as estimates until pricing.

🧠 Google Opens Gemini 4 Carbon To Every Paying Developer

Two weeks after handing Gemini 4 Carbon to cybersecurity defenders first, Google opened it today to all paid Gemini API developers in AI Studio, to businesses through Gemini Enterprise, and to Google AI Ultra subscribers in the Gemini app, Antigravity and AI Mode in Search. Google says it ranks first on CursorBench 4.0, Perplexity WANDR and Zapier AutomationBench at more than 2x lower cost per task than the next best outside model.

The catch is the price tag. Carbon costs $2 per million input tokens and $10 per million output through November 30, the same as Gemini 4 Argon, then doubles to $4 and $20. Google also reports a 92% pass rate on its agentic honesty test, up from 70% for Argon, and is previewing a new /swarm multi-agent mode in Antigravity.

Our take: the next three weeks are the cheapest Carbon will ever be. If you build agents, run your evals now at intro pricing so you know whether it earns the doubled rate in December. Every score here is Google's own.

Meituan published the open weights for LongCat-2.5 on November 9 under the MIT license, a week after introducing the model. It's a mixture-of-experts model with 1.6 trillion total parameters (the Hugging Face metadata lists 1.8T) and about 48 billion active per token. It's built for long-horizon agent work and reads images and video as well as text.

On Meituan's own numbers it scores 88.4 on Terminal Bench v2.1, up from 70.8 for its predecessor, and 64.6 on DeepSWE v1.1, up from 9.7. It still trails the top closed models on the newer Terminal Bench v4.0, 38.5 against Claude Opus 5's 53.9. The hosted API is on limited-time promo pricing of $0.30 per million input tokens and $1.20 per million output, per VentureBeat.

Our take: MIT-licensed weights at this scale are a gift to anyone who must self-host, but 1.6T parameters means serious hardware. For most teams the cheap API is the realistic way to kick the tires. Run your own agent evals, since every score above is self-reported.

Anthropic launched Claude Sheets and Claude Whiteboards in beta on every paid plan, made Claude Data generally available and showed off Claude Meetings for Google Meet, a direct shot at Microsoft's and Google's office suites days before its expected IPO. Google opened Gemini 4 Carbon to all paying developers at intro pricing that doubles after November 30, and Meituan released MIT-licensed weights for its 1.6-trillion-parameter LongCat-2.5. The thread: the AI labs no longer want to be a tab you visit. They want to be where the work happens.
